North Portland saloon brawl leads to assault charges

A 27-year-old man was arrested on assault accusations after Portland police say he knocked down a woman with his car, sending her to the hospital with life-threatening injuries. Another man suffered a injury when the car drove over his foot.

Police said Avery Camacho, 27, left a large bar fight at McMenamins White Eagle Saloon on North Russell Street at 12:16 a.m.

Avery Camacho, 27.

Camacho, who police said was intoxicated, drove away with a woman in his car crashed into a sign post about a block from the bar, police said.

The woman exited the car, only to be knocked down when the man put the car in reverse, ran over another person's foot and struck the woman with the open car door, according to police.

The woman, 29, suffered a significant head injury, police said. The man whose foot was run over is 28. Police have not released the names of either of the injured.

Camacho was taken to the hospital and later booked into the Justice Center Jail. He will be arraigned Monday on charges of driving under the influence of intoxicants, two counts of reckless endangering, one count of reckless driving, one count of second-degree assault, one count of third-degree assault and two counts of fourth-degree assault. His bail was set at $270,000.

10:45 a.m. Monday update: Portland police on Monday morning identified the two people injured in Sunday morning's North Portland incident.

Krystle Carruthers, 29, remains in critical condition at a Portland hospital with injuries described by police as life-threatening.

Jason Fahlman, 28, was released from a Portland hospital after he was treated for injuries suffered when his foot was run over by the car driven by Camacho, police said.

Southeast Portland bar shooting

Portland police say a man pulled a gun and shot into a crowd of people outside a Southeast Portland tavern early Sunday.

At 2:11 a.m. officers were dispatched to Dickey Doo's Pub and Grub, at 6618 S.E. Powell Blvd. Bystanders told police that a large group of people left the bar and were fighting on the corner when the man pulled a handgun from his waistband and fired into the crowd.

A person in the crowd shot back and the man and the crowd quickly dispersed. No one was hit in the incident.

Anyone with information about this shooting is asked to contact police at 503-823-4106.

Humboldt neighborhood shooting

Portland police are seeking information after gunshots were fired into a Northeast Portland duplex early Sunday.

Officers were dispatched at 3:17 a.m. to a report of shots fired in the 800 block of Northeast Webster Street, in the Humboldt neighborhood.

Police said bullets had gone through the walls of both of the duplex's residences.

The gunfire did not strike anyone, and police have no suspect information. Authorities ask anyone who knows about this incident to call 503- 823-4106.

Hillsboro shooting

A 23-year-old man was grazed in the shin by the ricochet of a bullet fired in downtown Hillsboro on Sunday afternoon.

Lt. Mike Rouches, a Hillsboro police spokesman, said a woman in her 40s fired a handgun into the ground during an argument.

The shooting took place in the 1700 block of Southeast Bush Street. The shooting remains under investigation.

Portland officer-involved shooting

Portland police are investigating the officer-involved shooting of a man they said threatened officers with a knife after he broke into an occupied home Sunday afternoon.

Sgt. Greg Stewart, a Portland Police Bureau spokesman, said the incident began at about 2:15 p.m. when a family member or friend called 911 to report that a man had been cutting himself inside a home on Southeast 14th Avenue.

The man, who has not been identified, was later spotted walking south through the neighborhood before he entered a home on Southeast Boise Street near 15th Avenue. A woman and two children were inside; they hid and called 911.

The woman and children were able to escape and were being escorted to safety by police when the knife-wielding man "abruptly" exited the house carrying a knife, Stewart said.

A sergeant fired a beanbag round from a shotgun at the man, but he continued to advance on the officers. A woman officer "was forced to use her firearm to defend herself," Stewart said.

Police have not released the man's name or his condition or the names of the officers involved; they have been placed on paid administrative leave.

Stewart said the case will be referred to a grand jury for review when the investigation is complete.

Anyone with information about the incident is asked to call police detectives at 503-823-0400.

Woodlawn neighborhood shooting

A 46-year-old man was shot during a possible gang-related shooting late Sunday night in Northeast Portland.

Just before midnight, police said, someone opened fire at a house in the 1500 block of Northeast Liberty Street.

Witnesses told police they saw several young men running south on Northeast 15th Avenue after hearing the sound of multiple gunshots.

Members of the bureau's gang enforcement team found multiple bullet holes in the home and are continuing their investigation.

The man was taken to the hospital for treatment of a non life-threatening bullet wound.
