Michael Burns, 53, a computer network repairman from Rochester, New Hampshire, was killed on the enclosed front porch of a duplex on Nye Street in Saco, Maine, in the early hours of September 30, 2017. Burns had been in town for work; what brought him to that residence after 1 a.m. remains unclear to his family and friends, who described him as a devoted father and Boy Scout troop leader and said he was non-confrontational.The tenant of the first-floor apartment shot Burns and immediately phoned police. Officers found Burns fatally wounded; he was pronounced dead en route to the hospital.

An autopsy attributed the cause of death to a gunshot wound to the head and ruled the manner of death a homicide. Three people were in the home at the time, including the tenant, and none of the others claimed to know Burns.Investigators concluded Burns had gone to the residence after responding to a Craigslist ad, an argument ensued, and the tenant fired the fatal shot. The Maine State Police later ruled the shooting an act of self-defense and no criminal charges were brought against the shooter, identified as Christopher Boure.

Does anyone have information about why Burns went to that Nye Street address or about the Craigslist ad he answered?
