Prosecutors on Thursday showed video of World Changers Church International members running for their lives after a Riverdale man fatally shot a member 12 times during a prayer service.

On Thursday, a jury watched the video, along with a couple witnesses to the Oct. 24, 2012 incident.

One of the witnesses broke down and testified she saw Floyd Palmer, a former member of the College Park church, shoot 39-year-old praise leader Greg McDowell multiple times, according to Channel 2 Action News.

“Why you still shooting?” witness Mary Lou Harris asked. “He’s already down.”

Palmer’s attorney said he’s mentally ill and thought McDowell and the church were out to get him, according to Channel 2.

Testimony in the trial will continue Friday in Fulton County Superior Court.
