A Sunday afternoon in May 2015 ended in violence on Colonial Creek Court in Wentzville, Missouri. Casey White, 38, of nearby Troy, was found dead of an apparent gunshot wound at a residence; police arrived about 12:30 p.m. and discovered his body after what investigators later described as a dispute that escalated.

The homeowner, 61-year-old Thomas McGovern, was identified as the suspect. McGovern was taken into custody at the scene and later charged with second-degree murder and armed criminal action; he was held on $100,000 bond as the case proceeded.

Few published details explain what set off the altercation or the events inside the house immediately before the shooting. Does anyone have information about White’s activities that day or about the relationship between White and McGovern?
