Ezell Walker, 20, was found fatally shot in the head in the yard of a vacant home on the 5200 block of Northland Avenue in Saint Louis in the early hours of April 22, 2015. Officers arrived just after 3 a.m. in the Kingsway West neighborhood after witnesses reported hearing a gunshot in a nearby alley and discovered his body; he was pronounced dead at the scene.

Walker was known as a rapper, singer, and boxer. Eyewitnesses reported a suspect fleeing the area immediately after the shot, and investigators say the attack appeared to be targeted after an earlier altercation involving Walker. Police identified a primary suspect, and an 18-year-old, Tevin Collins, was arrested and charged with first-degree murder and armed criminal action. At trial the jury found Collins guilty after prosecution evidence including witness testimony and forensic analysis was presented, and Collins received a lengthy prison sentence.

If anyone knew Ezell Walker, witnessed the shooting, or has information that could shed more light on what led to this targeted attack, please come forward.
