A Pinal County sheriff's sergeant is discussing Deputy Louie Puroll, who famously claimed on April 30 that a Latino drug smuggler shot him in the desert.

"I can't speak for our sheriff [Paul Babeu]," Dave Hausman says, "but I can speak for our unit, and the sheriff can slap me later if need be.

"But I think there's a lot of confusion that [Arizona Senate Bill] 1070 and what happened to Louie Puroll are intimately related. What happened out in [the] Vekol Valley was a criminal enterprise. Louie was looking at guys carrying drugs, whether they were illegal immigrants, citizens of the United States, or, in the darkest of dark realms, dirty cops or bad firemen.

"It's not about illegal immigration in that shooting. In that crime scene, it's about criminals shooting a cop. It was about one of our deputies who was fighting crime, for lack of a better Superman term, and got involved in a situation that was about crime. It was about smuggling drugs into the United States."

Hausman, an 18-year veteran of the south-central Arizona sheriff's office, supervised his agency's criminal investigation of the shooting.

The case thrust Pinal County Sheriff Paul Babeu into the national spotlight as a ubiquitous naysayer on the subject of the federal government and undocumented aliens, and it further polarized a citizenry already splintered by the illegal immigration issue.

The incident happened a week after Governor Jan Brewer signed S.B. 1070, Arizona's contentious anti-immigration law, and a month after Cochise County rancher Rob Krentz was gunned down on his cattle ranch, possibly by an illegal alien, in a still-unsolved murder ("Cowboy Down," June 10).

Deputy Puroll told investigators he was on a routine one-man patrol that April afternoon in the desert about an hour's drive south of downtown Phoenix and 85 miles from the Mexican border.

The 53-year-old officer said he was on a hill south of Interstate 8 when he spotted five or six men (Latino or Native American, he wasn't sure) walking north on a dirt trail below him. He said all but one were lugging large backpacks that he suspected held marijuana but that he hadn't seen any weapons as they passed by.

Puroll said he kept a safe distance as he followed the crew north for more than a mile across the rugged mountainous terrain. He said he stopped for a few minutes as the smugglers disappeared from sight over a ridge near Antelope Peak.

The search-and-rescue deputy said he, too, then stepped over the rise.

He knew from experience what was on the other side: a narrow, downhill wash dominated by shady mesquite trees and heaps of trash left behind by passersby — most of them undocumented.

Immediately after Puroll crested the ridge, he said, he ran smack into the guys he was tailing.

He said one of the men shot at him from about 25 yards "directly in front of me" with a powerful AK-47 assault rifle. That first shot, Puroll said, grazed his left flank a few inches above a kidney.

The deputy avoided further injury and retreated to safety, he said, after several more shots by a second smuggler missed their mark.

Puroll called 911 from his cell phone at 4:04 p.m.

Seven more shots rang out in rapid succession before the deputy said a word to the dispatcher.

Puroll immediately gave his GPS location, apparently reading from a handheld device. He then yelled, "Triple 9s!" the universal police code for an officer in trouble and needing help.

"I'm taking fire! Get me some help! Send Ranger [a helicopter]! I've been hit! I've been hit! I've been hit!"

Dozens of police officers immediately headed toward the remote vicinity , and records show some arrived near the junction of I-8 and State Route 84 within about 20 minutes. The intensive manhunt would include about 200 cops from local, state, tribal, and federal agencies.

Four helicopters began their search for the deputy and his assailants well within an hour.

But the "smugglers" escaped apprehension, and the packs that supposedly were filled with dope also vanished with them.

An Arizona Department of Public Safety chopper pilot airlifted Puroll out of the desert about 5:20 p.m., 80 minutes after the 911 call. The deputy was treated at the Casa Grande Regional Medical Center and released a few hours later.

Two of the helicopters were equipped with night-vision technology that detects temperature differences of objects such as vehicles and people. Pilots continued in vain to search for the supposed attackers that night.

Within a day, authorities had detained about 70 suspected illegal immigrants over an expanse far beyond the Vekol Valley. Pinal County authorities expressed hope that three "persons of interest" — undocumented aliens ensnared in the desert manhunt — would help break the case.

But they didn't, and the trio were turned over to immigration authorities for deportation.

The timing of the desert shooting couldn't have been better for Sheriff Babeu — "ironic," one of his lieutenants says, tongue not in cheek.

He soon emerged nationally as a more articulate, telegenic, and younger version of Maricopa County's blustery Sheriff Joe Arpaio. Babeu became a Fox News regular, eager to discuss the perils of a porous border and an inadequate federal response to illegal immigration.

That had been Babeu's agenda well before Louie Puroll got into the mix, and it had won him a starring role last spring in U.S. Senator John McCain's "You're one of us" campaign advertisement.

Now, the sheriff was able to add a heroic deputy to his increasingly visible storyline.

Babeu continues to claim that the "Mexican drug cartels" are running rampant in sections of his sprawling 5,400-square-mile jurisdiction, including the Vekol Valley.

"We still are outgunned, we are outmanned, and we don't have the resources yet to fight this," he tells New Times.

Shortly after the Puroll incident, the sheriff had to weather a media squall that began with a blog post on www.phoenixnewtimes.com in which police officers questioned the deputy's account ("Sheriff's Deputy Shooting . . . Has Some Local Cops Scratching Their Heads," May 3).

Babeu held a press conference on May 4 in Casa Grande. His presentation included close-up photos of Puroll's gunshot wound and selected audio snippets of his communications with 911 dispatchers after the incident.

"Tell my wife I love her," the deputy said in one sound bite that would be replayed repeatedly on national news shows.

A dispatch supervisor told the news media:"You can hear bullets ricochet near the phone," a reference to that seven-shot burst of gunfire at the start of Puroll's "I've been hit!" call.

She was suggesting that the bullets were fired at the deputy moments before he spoke up during the 911 call.

(However, many in law enforcement and others who have heard the tape say they are reasonably certain that Puroll fired those shots, not his supposed attackers.)

To bolster his deputy's credibility, Sheriff Babeu displayed infrared photos taken weeks earlier in the Vekol Valley showing what he called "squad-size elements using paramilitary tactics while escorting drug smugglers across the desert."

But the sheriff conceded that some information released by his agency in the hours after the incident was inaccurate:

• That Puroll faced at least 30 rounds of gunfire during the shootout. He didn't.

• That more than one helicopter had come under fire in the desert before Puroll was rescued. None had.

• That the smugglers left behind "bales" of marijuana as they fled. Authorities confiscated no contraband.

"We are in the business of facts and what really happened," Babeu told reporters. "This is a really big case."

The headline in the next day's Arizona Republic read: "Sheriff: Deputy's Shooting Not a Hoax."

A few weeks later, Babeu awarded Louis Puroll his agency's Purple Heart before an Arizona Diamondbacks game in downtown Phoenix. McCain was there to shake the deputy's hand.

Little has been written or aired about Louie Puroll since the sheriff's press conference.

But New Times has continued to examine the case, utilizing some of the best forensic minds in the country to assist in a four-month investigation.

The newspaper also analyzed reports filed by the DPS (which investigated the "crime scene") and the Pinal County Sheriff's Office.

In the end, key aspects of Puroll's account to authorities, plus an analysis of the reported crime scene (including photos of the deputy's gunshot wound), lead to this troubling conclusion:

The odds that Louie Puroll is telling the truth about what happened to him on April 30 are slim.

"This is not a he-said, she-said case," says Tucson private investigator Weaver Barkman, a retired homicide sergeant for the Pima County Sheriff's Office who analyzed the Puroll case at New Times' request. "This is about what the evidence says."

In Barkman's view, the evidence says, "Deputy Puroll's claims and versions are not supported by the physical, anecdotal, and behavioral evidence that I have reviewed. Several claims are in direct conflict with the physical evidence. There is, in my view, insufficient evidence to establish probable cause that on the afternoon of Friday, April 30, 2010, any person or persons, other than Deputy Puroll, were present at or in the immediate vicinity of this shooting scene."

And if the deputy is telling the truth, says Scottsdale forensic psychiatrist Steven Pitt, "You have a stunningly inept multi-jurisdictional response [on April 30] in addition to dealing with some really intelligent, athletic, and damned lucky smugglers."

Add to that a criminal investigation by Pinal County sheriff's detectives that was seemingly designed solely to clear their colleague Puroll.

"Our deputy says this happened, and there's evidence out there to support that it happened," Sergeant Hausman insists. "The facts are the facts."

But others interpret the facts quite differently from Hausman.

Dr. Michael Baden, co-director of the New York State Police Medicolegal Investigation Unit and former chief medical examiner for New York City, analyzed police photographs of Puroll's gunshot wound and concludes:

"I don't see what the problem is in calling this a close-contact wound. I don't know who did it, but the weapon was either touching this man or was within a couple of inches. It's pretty straightforward. It clearly is not a shot from a distance."

Puroll said in his May 3 interview with investigators that he was shot from about 25 yards away, not point-blank range.

Dr. Werner Spitz, co-author of the textbook Medicolegal Investigation of Death and the retired chief medical examiner of Detroit's Wayne County, agrees with Baden.

"This is a grazing wound fired at contact range," Spitz tells New Times.

But the equally experienced Dr. Vincent Di Maio — author of the textbooks Handbook of Forensic Pathology and Gunshot Wounds and retired chief medical examiner of San Antonio's Bexar County — says he isn't sure how far away the shot was fired, largely because Pinal County's investigation was inadequate.

Di Maio says he is "very suspicious" of the reddish discoloration visible around Puroll's wound. Such discoloration often is present with contact wounds and is caused by carbon monoxide-laden gases that emanate from firearms during discharge.

But, the doctor adds, "It's all going to hinge from the shirt as to whether it's a contact wound or not."

He refers to Puroll's bloody T-shirt and what he suspected would have been testing for telltale gunpowder, soot, and other residue.

Pinal County's investigators, however, chose not to send the shirt to the DPS' crime lab for analysis.

"I know you want to see if there's stippling [gunpowder patterns] on it to eliminate or prove it was a close-range shot, and that's legitimate," Sergeant Hausman says of the testing question.

"Yes, there will be gunpowder on there, but it will be extremely minimal because it comes from a distant shot. In my heart and mind, I believe Louie Puroll's story, and . . . I don't see the need for testing because we don't have a suspect."

Phil Keen, Maricopa County's former chief medical examiner, says he doesn't necessarily agree with the "contact wound" opinions rendered by Baden and Spitz.

Keen says the wounding shot may have been fired from the distance the deputy suggested but adds that the results of T-shirt testing and other investigative findings could change his mind.

"The difficulty is the inability to view the clothing in person or even see an official report of the clothing," Keen says.

"As regards the story of the shooting, it is improbable that persons carrying assault rifles would not know how to use them. And if they know how to shoot, why would they only strike with one bullet?"

It isn't the job of a forensic pathologist to speculate why Puroll might lie about the circumstances of his shooting. But analyzing possible reasons for why people behave is part of what Scottsdale's Steven Pitt does for a living.

Pitt has been a consultant to law enforcement in many high-profile investigations, including the JonBenét Ramsey murder, the Columbine High massacre, and the case of Franklin Brown, a former Phoenix cop who faked his own shooting ("A Shot in the Dark," March 2, 2002).

"You have an officer who was shot, and you don't have a clue about what happened to the alleged perpetrators or their loads of marijuana," Pitt says of the Puroll case. "That, in and of itself, raises a red flag as big as [Arizona] Cardinals' stadium."

The psychiatrist suggests several reasons why Puroll may have lied about what really happened:

• The deputy is a lone wolf who faked his own shooting and blamed illegal aliens to make a political statement and gain favor with his ambitious sheriff. ("That's pretty far out there," Pinal County Sergeant Hausman says.)

• He was involved in a ripoff of the smugglers that went bad. (Hausman: "Think about it. He's going to walk out in the middle of the desert and gun down six people who are carrying 80-pound packs? Even if you're taking steroids, you're going to hike the backpacks out two at a time? The obvious answer to, 'He's ripping off dope' is: not unless he's really, really stupid.")

• He was involved in an accidental shooting involving unknown parties and concocted a wild yarn to save face.

Pitt lists one more possibility — that Puroll was in cahoots from the start with his agency's upper echelon — but allows that the chances of that conspiracy theory holding up are small.

Deputy Puroll did not consent to an interview for this story.

Pinal County sheriff's spokesman Tim Gaffney says his agency's internal-affairs investigation is almost done and that Puroll wants to speak with the news media after his supervisors review the report and his attorney gives the go-ahead.

Sheriff Babeu tells New Times: "I honestly don't have any reservations about my deputy's account or his truthfulness."

Louie Puroll's path to his current position as a search-and-rescue deputy in Pinal County began in his native Michigan. It included tours of duty in the U.S. Army (he was a radio operator) and National Guard, and stints as a Texas cop and ranch foreman.

Puroll has been with the Pinal County Sheriff's Office for 14 years, first as a detention officer and now as a deputy. He has been a range deputy for about a decade, and his code name is "SAR 1," short for search-and-rescue.

Portions of Puroll's personnel file, which the agency provided to New Times (missing was his employment history), include commendations after praise from citizens and a few criticisms from his superiors.

In 2000, a supervisor wrote:"Deputy Puroll has experienced negative reactions from members of the public as a result of verbal usage not totally familiar to the local public."

The statement couldn't be vaguer, but it does get a point across.

Puroll's supervisor, Sergeant Brian Messing, has given him top grades for knowing how to rescue people — many illegal immigrants included — from potentially deadly situations in the unforgiving Pinal County desert that he knows so well.

But Messing also has given the deputy sub-par ratings regarding how he interacts with other police agencies — and on how he occasionally has treated victims, witnesses, and suspects.

"Louie is a very individualistic guy," the sergeant tells New Times, "and he's an alpha male, like the rest of us out here. He's very calm and cool, but when he's in a situation, his nervousness comes out as crotchety, and he barks. But I've never had to worry about his actions in a tactical sense."

Bruce Peterson, a Mesa Community College professor, says he met Puroll in 2005 when the deputy led a team into the Superstition Mountains to rescue him from dehydration. The following year, Puroll joined the professor on a student expedition back into the area.

"Louie is an expert in the back country," Peterson says, "and he's as honest and honorable as the day is long. He just has a way of telling the truth in a very graphic manner, and he's a great storyteller."

Peterson wrote in a journal after the expedition: "Everyone stayed up listening to Louie's colorful stories of African goldmines, wilderness rescues, and border crossings and smuggling."

Louie Puroll first checked in with dispatch at 8:57 on the morning of April 30.

The deputy drove his unmarked Chevy Tahoe SUV to work, ate breakfast at a restaurant in Arizona City, and then headed in the early afternoon toward the Vekol Valley, about 20 miles west.

By Puroll's account, he drove his four-wheel-drive Tahoe south into the desert at Double Gates Road, at the border of Pinal and Maricopa counties. It is at milepost 151 on I-8.

His supervisor, Sergeant Messing, was off that day. But Puroll apparently didn't inform anyone else in authority of his plans to patrol an untamed area that his sheriff has likened to a war zone.

He negotiated the bumpy, curvy dirt road for about four miles until he reached the end, and then parked his vehicle. Then he walked north for about two miles before perching above a well-traveled dirt trail that leads to the interstate.

The weather was moderate; the high temperature that day was just 70 degrees.

At 1:45 p.m., Puroll called a police dispatcher on his cell phone.

"This is SAR 1," he told her. "Do you have something to write with?"

"Um, yeah," she said.

Puroll said, "Write down these GPS coordinates," and then told her what he was up to:

"I'm up on the side of a hill watching a smuggler's trail. I don't need any help or anything. I just want you to know where I'm at. If I call you for help, I might be in a hurry and won't have time to tell you where I'm at, and now you know. Thank you."

Puroll was wearing khakis, a dark green T-shirt (he either was wearing a heavy long-sleeved shirt or carrying it around his backpack), a floppy hat, and combat boots. He said later his backpack held a blanket, water, a first-aid kit, and other survival items.

The deputy was carrying an M-16 rifle in a sling and had a Glock handgun in a holster. He also had a handheld GPS device, a new BlackBerry phone, binoculars, and extra ammunition.

All that immediately identified Puroll as a peace officer was his Pinal County sheriff's badge, which may or may not have been visible, on his belt.

What he didn't have in this "war zone" was a bulletproof vest or police radio, just his cell phone.

"We were switching out our old radios for new and better ones," Pinal County sheriff's Lieutenant Tamatha Villar explained later.

The GPS location Puroll gave at 1:45 p.m. was a mile and a quarter southeast of the coordinates he would give a dispatcher at 4:04 p.m., just after he said he was shot.

Puroll was incommunicado for two hours after the 1:45 call — at least, his cell records show no activity during that time.

At 3:42, he again called in.

"Hello, this is SAR 1," Puroll told the dispatcher, wheezing as he spoke. "Can you track this phone?"

She said she could and that it showed he was near the frontage road parallel to I-8.

"Look, I'm about eight miles south of the frontage road," the deputy said, sounding testy.

"Are you okay?" the dispatcher asked calmly.

"I'm just winded."

"Were you running?"

"Yeah, I got about eight people on foot in front of me carrying heavy backpacks. [They've] not spotted me yet. I'm standing about a quarter-mile back from them."

Puroll's phone got disconnected, at which point the dispatcher said to a colleague in an aside captured on tape, "Why would this fool be chasing people in the desert all by himself?"

It was a good question.

The dispatcher reconnected with Puroll within a few minutes.

"Listen to me," he told her. "I'm in the saddle [a mountain pass] south of the truck stop. I'm following five or six individuals. Big backpacks full of dope. I'm a couple of hundred yards back. They have not seen me.

"Don't send the regular patrol, and do not say anything on the radio — do it by telephone. I'll call you again when I can see them. They went over a little hill in front of me. Damn, I'm too old to do this."

"I know," the dispatcher said. "What are you doing out there by yourself?"

"I'm not by myself," Puroll replied quickly. "I've got about five or six guys. Bye."

This is where memories and evidence diverge.

Sergeant Messing says he was at home in Oracle grilling ribs when Puroll first contacted him about the smugglers:

"He says, 'Hey, I've got these backpackers. They're loaded. They've got dope, they're northbound, and this is where I'm at.' I said, okay, I'll get guys started out there, and he said, 'You know the area we're talking about.' He meant that if I called Joe Deputy out there, they'd have no idea how to get there or have the equipment.

"I said, 'Do the smugglers know you're there?' He says, 'No clue.' I tell him to keep his 300 yards back. Border Patrol does this all day long — follow the dope until you get your guys in an area, and then take them down."

Why, Messing is asked, would Deputy Puroll call an off-duty supervisor and not someone closer to the scene and on duty?

"I am his supervisor pretty much all the time," the sergeant says. "We have a unique unit."

Messing becomes emotional as he continues with his recollections of April 30.

"We had some bad tactics that day, errors we had to look at," he says. "As a supervisor, I'll take the heat on that. I probably should have told him to stop and turn around. But Louie's a very competent deputy."

But there's a problem with Messing's account:

Verizon cell-phone records (and Puroll's interview with investigators) suggest that Messing and the deputy didn't speak that day until 4:04 p.m., when the deputy says he was shot.

"I've been trying to figure this all out in my head," Messing says after New Times points out the discrepancy. "In my head, I'm sure I spoke with him right after he spotted those guys."

The records do show that a dispatcher contacted Messing at 3:50 p.m., shortly after she had spoken with Puroll.

The deputy spoke with a dispatcher again just after 4 p.m.

"This phone's gonna quit on me any second," he told her. "I'm coming down from the south toward the truck stop on I-8. We're passing through the saddle right now. It looks like we're headed toward that cell tower, and I think Brian [Messing] is trying to call me. Pass that on to him in case I'm not able to reach him. They're laid up in the brush ahead of me resting right now. So am I."

How the deputy knew that the smugglers were "resting" over a ridge a few hundred yards ahead of him is uncertain. And why he waited just a few minutes before moving over that same ridge into a known stopping point for undocumented aliens — alleged drug smugglers, in this instance — is another question.

Verizon records show that Brian Messing finally did contact Puroll at 4:04 p.m.

"I was asking him what was going on, telling him to stay back," the sergeant says. "I don't know how to describe it. You're in the mid-sentence of asking him how far away they are, and he says they're 150 to 200 yards away. He says, 'They're laying down, they're resting up.'

"I say, 'Don't move any closer.' Then, just like that, I hear the gunfire. A lot of shots. I could hear it in the background at a distance. Then I heard gunfire from his end start back. It boggled my mind. I got disconnected at that point."

Puroll dialed 911 seconds later.

Those 36 seconds — the "I've been hit!" call — later would be played across the nation and around the world.

Some of what transpired in the chaotic minutes after Deputy Puroll's 911 call is re-traceable through dispatch recordings, reports, and interviews.

Sergeant Messing took almost two minutes — an eternity under the circumstances — to call in after he and Puroll got disconnected.

"I was talking to Louie and I started losing him and it started like shots being fired," he told the dispatcher.

She calmly told Messing that they were on it.

At 4:08 p.m., Puroll again got through to dispatch.

"I had to move," he said, speaking loudly.

Where have you been hit, the dispatcher asked him.

"Left side above my belt. I don't have time to look at it. AK-47 rounds. There's at least three of them with AK's, maybe more. I can't tell. I'm gonna shut up so they don't hear me. You got my [GPS] position, so get here!" the deputy replied.

"Here" was more than three miles from the Vija Truck Stop on I-8 and more than four miles to Double Gates Road (from where Puroll had driven into the desert).

Afterward, Pinal County Chief Deputy Steve Henry insisted to the news media that Puroll's alleged assailants could have escaped in a "nearby" vehicle before what became a brigade of law enforcement started arriving.

But it takes an average person 20 minutes to walk a mile, even without having to carry a heavy backpack up and down mountainous terrain, a New Times reporter discovered..

GPS calculations by show that the distance south from the shooting site to the closest dirt road passable by car (near the deputy's vehicle) is about three miles, which would take at least 45 minutes to travel on foot. It would have taken the smugglers about another 15 minutes by vehicle over the treacherous dirt road to I-8. The escape to the interstate within 30 minutes of "I've been hit!" call would have taken about an hour.

If the smugglers had, instead, continued to walk north after shooting Puroll, it would have taken them at least 20 minutes on foot to get to a different dirt road by vehicle.

Then it would have taken them another 20 minutes to get to the rear of the Vija Truck Stop at I-8 and State Route 347 — about 40 minutes in all.

Certainly, the situation was fluid initially. "There were so many cops it was like an FOP [Fraternal Order of Police] convention out there," Sergeant Hausman recalls.

But what was the likelihood of six smugglers (with at least two would-be cop killers in the bunch) slithering away from the police in broad daylight with their heavy cache of marijuana?

"We learned a lot from the situation," Sheriff Babeu says, "about how to be better prepared and react and to marshal our forces so that bad guys aren't able to escape like these guys did. It was very unfortunate that they got away."

By about 5 p.m., the Pinal County Sheriff's Office set up a makeshift command post just off I-8 near Double Gates Road.

Puroll was on his cell phone almost constantly until the helicopter picked him up, conversing with Sergeant Messing several times.

"He told me he couldn't look at the wound," Messing recalls. "I asked him if it was gushing blood, and he said it wasn't."

Puroll was somewhere south of the shooting site, a good distance from where he had parked his Tahoe hours earlier.

"Getting shot ain't no fun at all," he told a dispatcher at one point.

A few minutes later, Puroll blurted, "I'm gonna go. I'm gonna get busy here in just a minute."

The dispatcher asked him what was going on.

"The guys with the rifles are coming back. I'm gonna try to make it back to my truck. Bye."

The deputy then hung up.

The DPS helicopter pilot lifted Puroll out of the desert about 5:20 and took him to the command post.

Puroll spoke there with Babeu before an ambulance took him to the Casa Grande Regional Medical Center for treatment.

Pinal County deputies found the apparent shooting site near Antelope Peak before nightfall.

It was familiar to the deputies who work search-and-rescue, a final resting stop for untold undocumented immigrants before they walk the last few miles to I-8 on their way to Phoenix.

"It's a natural bottleneck," Puroll said later, "and it's the only practical way for a person to walk, unless you just want to go straight across country over mountains."

The site is an environmental disaster, with literally hundreds of plastic water bottles, ratty old backpacks, tattered clothing, the remnants of Mexican pharmaceuticals, blankets, and other rolls of toilet paper.

The officers eyed lots of ammunition, expended and otherwise, in the "bottleneck," including dozens of shell casings clustered near the top of the ridge.

They also saw a Glock handgun near the spent casings.

It was Louie Puroll's — he had left it behind.

The deputies retreated to the command center by helicopter before it got too dark.

Babeu and his top staff (accompanied by a senior prosecutor from the Pinal County Attorney's Office) decided to ask the DPS to process the scene the next morning. Pinal County would keep the officer-involved shooting and internal-affairs investigations in-house.

Sheriff's personnel photographed Puroll's gunshot wound at the hospital. The photos later served as the basis for the expert opinions of the pathologists contacted by New Times.

The police also took photos of Puroll's bloody T-shirt and of several other items of evidence, including the deputy's firearms.

DPS investigators wanted to speak with the deputy that night, but Puroll already had been released from the hospital by the time a detective got there.

DPS and Pinal County investigators returned to the desert shooting site by helicopter the next morning. The state cops canvassed the clutter, taking hundreds of photographs and noting the GPS coordinates of the evidence they collected.

They recovered the Glock left behind by the deputy and, a few feet from the gun, his GPS unit and other items.

Forty-six shell casings from Puroll's two guns — the Glock and the M-16 — were nearby.

The presence of the casings suggested that he had discharged his weapons from the GPS location he shouted out at the start of his "I've been hit!" call.

The investigators also found nine expended shell casings that hadn't been fired from Puroll's two guns in the "crime scene."

Six of the casings came from AK-47 rifles (though it hasn't been determined whether they were from the same gun), and three came from a .45-caliber handgun.

Two of the AK-47 cartridges were within a few feet of the casings from Puroll's guns, but they were badly rusted and practically embedded into the ground.

The other four AK-47 casings appeared newer.

According to GPS calculations, they were close to each other, about 35 yards downhill from the deputy's Glock.

But, importantly, they were not in the general area where the deputy claimed that he had been fired upon by the first shooter.

Three .45-caliber casings were another 18 yards behind and to the left of the four AK-47 cartridges, looking downhill from Puroll's perspective.

By May 3 (three days after the shooting), Louie Puroll — reportedly a victim of attempted murder — retained a Casa Grande attorney who represents the Pinal County Deputies Association.

That morning, two investigators from Pinal County and two more from the DPS planned to return to the desert with Puroll for a walk-through of the shooting scene.

The attorney, Denis Fitzgibbons, laid ground rules:

Investigators would be limited to asking about where Puroll was standing when he was shot and when he was shooting, the directions he shot, and where the men were when he shot at them.

One more thing: The walk-through couldn't be audio- or videotaped. Remarkably, both police agencies agreed to the attorney's stipulations.

Pinal County Sergeant Hausman and case agent Todd Nelson got their chances to speak with Deputy Puroll (with attorney Fitzgibbons present) later that day back at the main sheriff's station.

Police detectives utilize various techniques when interviewing suspects, witnesses, and victims. Some let the subject tell a story with little interruption before circling back to dissect the story detail by detail.

Puroll spoke deliberately during the 47-minute interview, sounding at times as if he were telling a mesmerizing war story around a campfire.

The two Pinal County detectives listened to their colleague for 26 minutes straight at one point, as the list of obvious follow-up questions mounted. But neither Sergeant Hausman nor Detective Nelson would challenge any part of the dramatic monologue.

Puroll told of following smugglers carrying "large, rectangular backpacks, probably 50 to 60 pounds each. I knew roughly where they were going — that trail goes one place — up the mountain and over and down straight to the truck stop."

Puroll described the backpackers as "big strong men. They weren't the typical UDA [undocumented aliens], much stronger than the average illegal."

The deputy said he was "hoping to interrupt them on the other side of the mountain near the truck stop, or at least where they stashed the dope. At this point, I did not intend to confront anybody or try to arrest anybody, or anything. I was way outnumbered."

Puroll said he stayed back as the smugglers marched over a ridge and disappeared from sight:

"I was telling myself that if something was going to happen, these people would be up close, and there would be more than one of them. I did not know that anybody was armed . . . but I was out there by myself. There was more of them then there was of me."

Puroll said he then decided to step over the rise, after he reset his M-16 rifle to fully automatic, turning it into a machine gun.

"I knew they had to be up there somewhere, I didn't know just where," he said. "I didn't see anybody, didn't hear anybody. So I checked my phone, and I had a phone signal. "

He said his sergeant, Messing, then called him. It was 4:04 p.m.

"Dispatch evidently had advised him what was going on, and he was headed my way, and he was calling me to find out what I was doing. And the first thing Brian says, 'Where are you?'

"And as he said that, a man stood up in front of me about 25 yards away. I had my cell phone in my right hand and my GPS in my left hand. I had just read my GPS location to the dispatcher, and I still had everything in my hand, and that guy stood up in front of me.

(Puroll didn't give his new GPS location until after the "I've been hit!" call. That location was where he would soon leave his Glock and the GPS unit behind, and where he told the investigators during his May 3 walk-through that he had been standing.)

"Without a moment's hesitation, without a heartbeat, he brought the weapon up to waist level and began firing what looked to me to be a fully stocked AK-47," Puroll said of the alleged smuggler. "He was firing from the hip. I saw the first round go off, a micro-flash from what I believe was the first round, and I felt the impact. "

(GPS coordinates show that Puroll was about 14 feet above where he said the first shooter was, a significant detail for the forensic pathologists who analyzed the gunshot-wound photos. "It's almost a level shot if you think about it," Vincent Di Maio says. "It definitely would be difficult for a shot coming distinctly uphill like that to cross his body as it did.")

Puroll continued: "When I saw him, I had dropped my cell phone and my GPS to the ground and grabbed my rifle, which was slung in front of me, and began to bring it up. Before I could get it up to shoot, his first round struck me in the side. I felt it. It felt like being popped with a wet towel . . . I knew I'd been hit, and I knew if I went down or stopped shooting, there was a good chance I was gonna be killed."

Puroll said he fired at his assailant and saw him fall to the ground: "He immediately went out of my sight. I never saw him again . . . No one spoke a word.

"Before I could do anything else, I started taking fire from my right; a rifle and a pistol began firing off to my right, as close or closer to me than [the first shooter] was. Everything occurred within a 25- to 30-yard circle, at most."

Puroll said he dropped to the ground, as more rounds whizzed over his head. He said he emptied his rifle while he was sitting there and then laid that weapon on the ground and drew his pistol.

Detective Nelson speculates that the smugglers may have had "brass catchers" on the end of their AK-47s to snare the used shell casings, which would keep their DNA from discovery — and would account for the paucity of AK-47 shell casings.

But Luke Haag, technical director of the Phoenix Police Department's crime lab for 17 years before retiring, says, "I have yet to be aware of a crime scene in my 45 years in the business in which a brass catcher was used. And getting DNA off fired cartridges is virtually impossible. It sounds like . . . this is scrambling for an explanation."

During the firefight, Puroll said, he took a fresh M-16 ammunition magazine out of his pocket with his left hand and reloaded the rifle:

"At this time, my pistol went empty. I laid it on the ground and picked my rifle back up . . . Everybody quit shooting at this point."

Puroll said he took the opportunity to reload his Glock, "and I thought I put the pistol back in the holster. I picked up my rifle. I picked up the cell phone that was on the ground and put it in my shirt pocket. Grabbed my pack — my pack has water in it and my survival gear. I knew I had to get out of there before they could pinpoint just where I was."

The deputy's statement about the backpack raises questions about how, when, where, and, specifically, why Puroll took it off his back.

Was he carrying it for some reason when he crested the hill (along with his phone and possibly his GPS unit)? Weaver Barkman, the former homicide detective, says, "Carrying a pack into a situation like he has described is out of the realm of reality. And the likelihood of him taking off when he's being fired at and he's trying to save his life? Improbable."

Asked about the backpack, which later showed no sign of damage from gunfire, Sergeant Hausman says, "I honestly don't know how to answer that."

Puroll described how shots continued to sail over his head as he retreated about 50 yards and moved off the dirt trail.

It was only then, the deputy insisted, that he made his "I've been hit!" call to dispatch.

Cell-phone records and dispatch recordings refute this. They show that Puroll called at 4:04 p.m. from the spot where he emptied his M-16 and Glock. The spot is precisely where he dropped the Glock and the GPS unit, not more than 50 yards back.

Shortly before the helicopter picked him up, Puroll recalled, he heard in the distance "four distinct pistol shots: Boom, boom, boom, boom. And I remember thinking, 'Gunmen are shooting the guys carrying the backpacks. They don't want anybody to identify them.'

"That just flashed in my head. Or the guy that I had shot was wounded bad, and he was a liability and a burden to them."

Investigators found no signs of blood at the shooting scene and recovered no bodies from the area.

Sergeant Hausman had but one question of the deputy at the end of the interview — what was the first shooter's intent.

"He was intending to kill me," Puroll replied.

Brian Messing is standing on a dirt road in the Vekol Valley, a few yards from where Puroll parked his SUV on April 30.

At dawn, the sergeant and a county SWAT team, along with case investigators Hausman and Nelson, had led a New Times reporter to the shooting site near Antelope Peak.

Everyone but Messing and the reporter left the area after returning to the Vija Truck Stop a few hours later.

Messing tries to explain himself and his role in this complicated and significant case.

"I wonder," he says, "did [the alleged smugglers] hear me on the phone when I was speaking with Louie? Did I screw up? It kind of eats you up."

The sergeant says he did not write a police report of his role as a possible "ear-witness" to the shooting because no one asked him to. And he notes that criminal investigators didn't interview him until almost three months after the incident.

"Listen," he says to the reporter, "I believe Louie, but I understand why you're here. Normally, when smugglers see an officer, they're gonna drop the dope and run, but things have been changing out here. They lose the dope, they can get killed. I know it sounds like political hype that people get on, but this area's gotten that bad."

It has gotten that bad.

In early June, a drug smuggler called 911 after he and a friend were shot in the Vekol Valley.

The caller told a dispatcher in Spanish that he had been shot "right here where they shot the sheriff," a comment that Babeu says, in a sense, corroborates Puroll's tale.

Messing reiterates that Puroll has had "enough life experience, military and law-enforcement experience to have handled this. Louie takes care of himself. If there's a dirty cop, get him. But you gotta know this guy."

Puroll is back on the job, though Babeu doesn't allow range deputies on solo patrols anymore.

"He's out there stubborn as ever, doing his thing," Messing says of the deputy. "That's just Louie.

"My own opinion is that Louie is clean . . . but I don't have all the answers. Maybe there are people out there who do."



Pathologists. Baden, Spitz, and Di Maio independently examined the photos taken of Puroll's gunshot wound before replying to New Times.

"There is black powder along the edges of the [wound], a furrow along the edges," says Baden, who also is the chief forensics consultant to Fox News and, thereby, one of the more visible forensic pathologists in the nation.

"You just don't see that in distance wounds. Also, the pink discoloration around the outside of the wound is from carbon monoxide that always shows up when a weapon is fired at close range."

He adds, "If someone wants to cause a grazing wound, they can easily do that without fear of sustaining a more serious injury than this individual sustained."

Di Maio says, "That looks to be a contact wound. It's got all that suspicious red color, which is carbon monoxide and usually means contact, and [there is] all that black stuff around it, which gets you thinking it probably is soot from the contact wound."

But he says he's not comfortable with rendering a definitive opinion.

"The area around this superficial wound should be seared — the bullet came through at 1,400 degrees, you know — but I don't see any soot or searing. It's real complicated. Soot could have been wiped away from the wound, and we don't know exactly at what point in treatment [of the injury] that the photos were taken. But I think that this case [would] be called on the T-shirt, not on the wound."

Luke Haag, president of Carefree-based Forensic Science Services and author of Shooting Incident Reconstruction, says, "If there are issues about direction and distance, and the first thing that bullet hit was clothing, the clothing will win the day for somebody. That shirt would tell you whether it's contact, near contact, or a distance shot.

"Pinal County's not submitting that T-shirt for testing is definitely troublesome," he adds. "Sometimes, the police don't wear the white hats. I hope that's not the case here."

Retired homicide cop Weaver Barkman says Louie Puroll's story doesn't work on a number of levels.

"Were the deputy not a law-enforcement officer," he says, "the conflicting evidence would likely result in a finding that his claims were fabricated and expose him to criminal and civil action."
