What had happened

The man lived on a farm, where he carried a great life. Well-known, 14 years of marriage to an ex-model. Woke up every day at 5 a.m. since the day he returned from the war. He seemed to lose his mind when the death of his wife occurred. He was abusing his power as a veteran of foreign war, getting into places only he could with his VFW acknowledgement, by stealing and abusing people. He then moved out to his mothers, where he met up with his ex-fiancé. He then began to get better. More and more with time, she seemed to do him good. Then one day he came home to walk in on her with someone else. He lost it. Went to the basement and grabbed his stolen gun, came back upstairs and shot them both. He left town immediately and was never heard from again. The gun was traced back to a man, who had reasonable cause to be not suspected, and claimed that the gun had been stolen a couple of months back.
