Omar Berry, 43, was fatally shot in his Mission Street residence in Pittsburgh’s South Side Slopes in the early morning of September 14, 2017. Police responded to a 911 call shortly after 5 a.m. and found Berry on the second floor with at least one gunshot wound; he was pronounced dead at the scene.

The initial call came from 42-year-old neighbor Louis Dickerson, who first told investigators an unknown intruder had shot Berry. Scene evidence — including a bullet hole on the inside of Dickerson’s apartment door — contradicted that account. Dickerson changed stories, briefly blaming a man nicknamed G, before ultimately confessing. He said the two had been drinking and playing cards, argued over money, and that he shot Berry believing Berry was reaching for a gun; he later said Berry was unarmed. Dickerson led police to a hidden revolver and was charged with criminal homicide, tampering with evidence, and a firearms violation; a judge ordered he stand trial and he was held without bail.

Did anyone in the neighborhood know Berry or have information about his relationships with neighbors or the events that night?
