On a Monday in January 2015, 34-year-old Greg Powell was shot and killed while shoveling his neighbor’s driveway on Detroit’s west side. Witnesses working nearby heard two shots; they and a coworker ran to his aid and found him with a gunshot wound to his face. They performed CPR until emergency medical services arrived, but Powell’s injuries proved fatal.

Surveillance footage reportedly captured the assailant firing a second shot after Powell had fallen. The suspect was described as an African American man wearing a Carhartt jacket and was last seen running from the scene on foot. No motive was immediately clear.

Powell lived with and helped care for his 87-year-old grandmother; family described him as a standup guy devoted to his relatives. The investigation was ongoing and police continued searching for the gunman. If anyone has information about that January 2015 shooting or the man seen leaving the scene, please share what is known.
