Derrick J. Vaughn, 28, was shot to death on May 21, 2018, during a card game at the Alton Acres Housing Development in Alton, Illinois. Vaughn, known as DJ, died alongside another man, Elijah S. Ingram. The Major Case Squad of Greater St. Louis was called in to assist the investigation.

Authorities identified Vincent Gordon, 36, of Alton, as the primary suspect. Gordon, who was on parole at the time, was arrested and charged in the deaths. In October 2018, Gordon was convicted of the murders and related charges, including unlawful possession of a weapon by a felon and escape by cutting an Illinois Department of Corrections ankle bracelet, and received a mandatory life sentence without the possibility of parole. Derrick Vaughn is remembered by family as a devoted father to two young sons and an active community member.
