On July 22, 2014, Glenn Pookie Walker Jr., a 39-year-old contractor and father of four, was killed in a shooting in Pittsburgh’s Homewood neighborhood. Walker was working on a vacant two-story house on Albion Street with his childhood friend and business partner, Raheem Watson, and at least one other person who had come to discuss the work. An argument broke out just before 4:30 p.m., neighbors reported hearing numerous shots, and Walker was found lying in the middle of the street with multiple gunshot wounds. A fired gun was recovered next to his body and he died at the scene. Watson was also struck, suffering an eye injury that later required surgery.

Walker's mother, Nancy Walker, described him as a good man who was loved by everyone and had no known enemies; neighbors said the shooting shook a neighborhood that had been undergoing significant renovation. Pittsburgh police were searching for the third person present during the argument and asked anyone with information to come forward.

If anyone knew Glenn, Raheem Watson, or the person who was with them that afternoon, can you help investigators by sharing what you know?
