The Belleville News-Democrat reported late Friday afternoon that Brad Coleman, brother of convicted Columbia triple-murderer Chris Coleman, has resigned his job as a prison guard at Menard Correctional Center in Chester effective Feb. 28, disqualifying him from obtaining disability per a recent claim of post-traumatic stress disorder.

The Belleville News-Democrat reported earlier last week that Brad Coleman, 35, who was currently on unpaid leave at the time from Menard Correctional Center in Chester, said constant worrying about his brother caused him to have PTSD.

Watching other prisoners serve life sentences reminded him of his brother, the paper reported him as saying. Chris Coleman is serving concurrent life sentences in an out-of-state prison for the May 2009 strangling deaths of his wife, Sheri, and the couple’s young sons, Garett and Gavin, inside their Columbia home.
