Warren Dewayne Sims was 28 when he was killed on December 13, 2003, in Birmingham, Alabama. He was shot as he was leaving a store on Avenue E; investigators say two suspects followed him from inside the establishment and opened fire as he tried to flee.

No arrests have been made. The identities of the two people seen fleeing the scene remain unknown to the public, and the motive for the shooting has not been established. The Birmingham Police Department revisited the case on the 20th anniversary of the homicide to try to generate new leads.

If anyone remembers seeing activity around that store on Avenue E on December 13, 2003, or knows anything about the two people who fled, please share what you know with investigators.
