Trevon Deandre Vann, a 23-year-old from Houston, was fatally shot at his apartment at 7800 West Airport Boulevard on December 4, 2015. The shooting occurred about 1 p.m.; Vann was taken to Ben Taub General Hospital where he was pronounced dead.

Witnesses reported hearing a gunshot and a scream, and saw a man get into a maroon car and leave. Vann was also seen being placed into a silver Saturn by two men while a third man drove. According to police reports, two friends, Brandon Dontae Dace and Daylon Henderson, admitted to roles in Vann’s death and were arrested and charged with manslaughter and tampering with evidence. Vann’s roommate and two other friends were at the apartment and, investigators say, provided vague information and became uncooperative.

What information do readers have about the maroon car, the silver Saturn, or anyone who witnessed the events around 1 p.m. that day?
