Prosecutors say Jermaine Williams, 47, recently was found guilty of shooting Joshua Lee seven times in the back in the store's parking lot while dozens of shoppers were present.
Williams reportedly told Amite Police when he was arrested June 17, 2015 that Lee glared at him through store windows, so he had to respond.
“I had to protect myself. He had brass knuckles,” Williams claimed.
Along with that, Lee was working on a construction job next door to the store.
A Facebook post by District Attorney Scott Perrilloux says Williams parked his car behind Lee's girlfriend to create a trap. The girlfriend told detectives that Williams and Lee had a tense relationship.
Williams had five children in his car when he shot Lee.
Perrilloux told WAFB-TV that Williams used not only a self-defense argument during his trial, but claimed to have a mental disorder which made him insane.
According to the Baton Rouge Advocate, a jury needed about three hours to find Williams guilty.
This was Williams's second trial for second-degree murder. The first trial in 2018 ended with a deadlocked jury.
