Steven Johnston was 51 when he was found dead inside the upstairs apartment he shared with a roommate on the 400 block of South White Horse Pike in Audubon, New Jersey. Officers responding just before 3 a.m. on January 31, 2015, discovered Johnston after he sustained a gunshot wound to the head inside the confined living space.

Clark III, escalated shortly before the shooting. Clark told police he became upset, produced a handgun and fired. He remained in the apartment, called 911 to report that he had shot his roommate, and was taken into custody at the scene. The firearm was never recovered.

Prosecutors charged Clark with first-degree murder and related weapons offenses; he later pleaded to an amended count of first-degree aggravated manslaughter and received a 20-year term in December 2016. Did anyone nearby that night see or hear anything that could fill in why the argument turned deadly?
