Derick Thomas was 19 when he and 18-year-old Keith Sims were found fatally wounded by gunfire on the evening of April 19, 2017, in Bellefontaine Neighbors, a suburb just outside St. Louis, Missouri. Investigators described the scene as a double homicide; police opened a homicide investigation but the circumstances that led to the shootings were not immediately clear.

The case has grown cold over the years, and the families and community continue to await answers and justice for the two young men.

If anyone has information about what happened that night or about Derick Thomas or Keith Sims’ last known movements, please come forward to assist the investigation.
