The last moments leading up to Sgt. Tim Prunty's death were caught on Circle K surveillance video.
According to testimony, Sgt. Prunty went to the Circle K to check on clerk Carey Sonnier because he thought it was unsafe for her to work the overnight shift. In fact, he was known for checking on overnight clerks.
Sonnier testified that as he walked in, he began talking to her about a song he was listening to. She said it was from a band she had never heard of, and they had a good laugh.
Just moments later they were both standing outside by Prunty's police car when Christopher Cope pulled up in his car, got out, and fired his gun, hitting Prunty five times. Prunty died from those wounds.
Cope was convicted of first-degree murder and sentenced to life in prison.
Some of the evidence released to KSLA News 12 was radio traffic between officers and dispatch.
The first responding officer was Cpl. Naomi Johnson. She could be heard telling her dispatcher "Sergeant down, sergeant shot. My sergeant has been shot!"
When she arrived on the scene seconds later, she saw Prunty lying on the ground.
With panic in her voice she tried to get Prunty medical help, all while trying to coordinate the capture of the shooter.
"A red Camaro went West bound, Bert Kouns," yelled Cpl. Johnson.
After a chase that was all caught on dash-cam video Cope finally pulled over near Financial Plaza. Police could be seen hitting Cope several times while on the ground. Police officers who made the arrest testified that while Cope wouldn't surrender his right hand to be cuffed, and officers landed what's called distraction blows for compliance.
"No reasonable explanation, just stupidity," Cope could be heard telling investigators on an audio clip that was submitted as evidence.
Jurors heard, in his own words, what he was thinking at the time of the shooting.
The investigator asked, "What exactly, were you trying to do whenever you got out and started shooting?"
"I guess just trying to end it," Cope replied in a soft voice.
Cope never took the stand during his murder trial, but his defense team made up of Dwight Doskey, and Bruce Whittaker argued that Cope was depressed and suicidal that night.
Prosecutors, Dale Cox and Brady O'Calaghan told the jury that his intent was to kill Prunty, and others that night.
