Nine minutes of an increasingly intense confrontation had elapsed when former University of the Incarnate Word police Cpl. Christopher Carter issued an ultimatum to Robert Cameron Redus: “Stop or I will shoot.”

“You’re gonna (expletive) shoot me?” Redus, a 23-year-old UIW senior, responded, according to audio released Thursday that for the first time shows in graphic detail what happened in the Dec. 6, 2013 altercation.

“You’re gonna (expletive) shoot me? For trying to make you not choke me right now?” Redus added after Carter warned again that he would shoot Redus.

The struggle in the parking lot of Redus’ off-campus apartment complex went on, with Redus asking the question several times, as if he were in disbelief that the officer was really threatening to shoot him.

“You are pathetic,” Redus then told Carter.

As Carter continued to order Redus to stop, Redus asked again: “You’re gonna shoot me if I don’t stop? Is that what cops do?”

Redus cursed at Carter. The seconds that led to the shooting were filled with what sounds like a scuffle.

“Stop. Stop. Stop. Stop. Stop! Stop! Stop!” Carter said. “Get back. Get back.”

Then: the sound of six shots being fired, over about eight seconds.

The release of the audio more than 15 months after the incident came after a grand jury Tuesday decided not to indict Carter, clearing him from facing criminal charges in the shooting in Alamo Heights. It largely backed up what officials have said in the days since the altercation — that Carter told Redus repeatedly to “stop” or “stop resisting” and to put his hands behind his back. He also told Redus a few times that he was under arrest or was resisting arrest.

The recording is the first time the public is able to listen to Carter’s explanation of what happened as he talked to Alamo Heights police, paramedics and possibly a lawyer he called on his cell phone. It was captured on a body microphone Carter was wearing.

“I tried to restrain him. He tried to kick me in the chest,” Carter said at one point to an Alamo Heights officer who responded to the scene after the shooting.

But the audio also reveals the problems other officers had in reaching Carter. The officer radioed an incorrect location to dispatch when he first stopped at the complex, and responding officers did not know where Carter was until after Redus was shot.

At one point during the struggle, Carter even asked Redus what the address was and what street they were on.

After Carter opened fire on Redus — hitting him five times — he radioed to dispatch: “Shots fired, send EMS. I have one down.”

As Carter worked to catch his breath, the dispatcher told him to hit his emergency toner.

“We can’t locate you,” the dispatcher said. “Your location please, give me your location.”

Carter tried to describe his location using geographic landmarks and said he was behind a bank, initially misidentifying which bank.

More than three minutes after Carter fired his weapon, an Alamo Heights police officer arrived at the complex.

“Right here!” Carter called out. “He’s down, we need an ambulance. I had to shoot.”

He later made a phone call to someone who was possibly an attorney.

“I’m at Alamo Heights,” he said on the phone. “I was trying to stop a drunk driver. He tried to get into his apartment complex.”

Redus started resisting, Carter said, and knocked away the officer’s radio.

“He took my baton away,” Carter said later in the recording. “Did a couple smacks on my left shoulder. I don’t know if one of them hit me on the back of my head or not. I knocked it out of his hand. I got him in a headlock. He started punching me in the face. He got away from my grip. He had an opportunity to leave. He charged me again.”

Carter said he was feeling fatigued as the fight dragged on.

“I drew my weapon, ordered him to stop, stop. He came at me again, punched me in the face and I fired. I don’t know how many times, like four, five. Put him to the ground. I was able to regain my mic and call for assistance.”

When Carter first approached Redus and ordered him to put his hands behind his back, Redus told the officer, “You’re freaking me out, man” and “I feel like I’m gonna get raped right now.” Much of what Redus said is muffled, but he also said several times that he was trying to prevent Carter from choking him.

After the death of Redus — who went by Cameron — his family filed a civil wrongful death lawsuit against both UIW and Carter. The suit is making its way through the court, and the family’s attorney said this week that the lack of indictment neither helped nor hurt the case.

But the attorney, Brent Perry, said, “We believe that if the district attorney’s office had seriously pursued an indictment, there would have been an indictment.”

In a recent filing in the civil suit, the family’s attorneys disputed whether Redus ever wrested the baton from Carter and struck him. The lawyers also have argued that Carter lacked probable cause to pursue and arrest Redus.

During the struggle, Carter never specifically mentioned the baton, according to the audio. But he told responding officers that Redus had taken the baton and struck him with it.

Carter told investigators he started following Redus along Broadway around 1:30 a.m. that December morning because he believed Redus was driving drunk, which was confirmed by an autopsy.

Carter, who was on duty, did not know that he was pursuing a student at the time, but as a licensed peace officer, he was authorized to arrest suspects outside his jurisdiction for serious offenses, including drunken driving, legal experts have said.

Carter has since resigned from the force.

The Redus family is seeking between $1 million and $26 million in damages in the civil lawsuit.

In a statement released by its attorneys, UIW said Thursday it hoped the recording would “put to rest much of the misinformation disseminated by persons characterizing the recording.” The statement also tallied the number of times Carter told Redus to stop resisting and to put his hands behind his back.

“While this is not all the evidence viewed by the grand jury, we are confident that any objective listener will conclude Cpl. Carter acted properly,” the statement said.
