Stephenville, Texas (CNN)A former deputy testified last week that he overheard the defendant in the "American Sniper" murder trial explain why he killed two men. Gene Cole, who worked for the Erath County Sheriff's Office at the time, testified Friday that on June 22, 2013, he "heard Mr. [Eddie Ray] Routh say, 'I shot them because they wouldn't talk to me. I was just riding in the back seat of the truck and nobody would talk to me. They were just taking me to the range so I shot them. I feel bad about it, but they wouldn't talk to me. I'm sure they've forgiven me.'"
