PHOENIX -- An Arizona jury is expected to hear closing arguments and perhaps begin deliberations Tuesday in the trial of a one-time cop that shot and killed a North Texas man in 2016.

Phillip "Mitch" Brailsford faces second-degree murder charges for the killing of Daniel Shaver, from Granbury.

Closing arguments in the trial are set for Tuesday morning. Observers tell WFAA those could be wrapped up by lunch, with the jury set to begin their work after that.

During a six-week-long trial, prosecutors in Maricopa County have tried to paint Brailsford’s actions on a dark January evening in 2016 as “reckless.”

Mesa police were called to a motel after a report of a man with a gun. Turns out, it was Shaver showing off an air-pellet rifle he used for work.

Brailsford opened fire as Shaver crawled out of his motel room while reaching for his pants, which were falling down. He was unarmed but intoxicated at the time.

According to a Mesa police report, he was crying “Please don’t shoot me” directly before Brailsford opened fire.

The jury recently saw body camera footage depicting those fateful moments.

Brailsford was fired by the Mesa Police Department after an investigation.
