Mark Green, 43, was killed during an early-morning altercation inside a Devilliers Street residence in Pittsburgh’s Hill District in November 2015. Police responded to a disturbance shortly before 5 a.m. on a Sunday and found Green unresponsive; paramedics pronounced him dead. The Allegheny County medical examiner ruled the death a homicide by strangulation. His mother said he also sustained a blow to the head during the fight, though strangulation was listed as the cause of death.

A resident of McKees Rocks, Green worked as a music producer and was a father in a large family; his sister said he tried to steer children away from violence. At the time of initial reports no arrests had been announced and the city’s Violent Crime Unit was handling the investigation. If anyone knew Mark or has information about what happened that night, please come forward to assist the investigation.
