Marcus Griffin, 26, was shot and killed on the evening of June 8, 2014, on Central Park in Rochester, New York. He had gone to the area to return his children to their mother; the shooting occurred around 8:20 p.m. Responding officers found Griffin with a fatal gunshot wound to his upper body, and family members later identified him.

Authorities arrested 23-year-old Jarrell Dwayne Riley of Rochester and charged him with second-degree murder, alleging Griffin was shot in the head with a rifle that had been reported stolen from a city home in 2009. Riley pleaded not guilty; the stolen-property charge was later dismissed. Griffin’s family described him as a devoted father to three young children, and court appearances were marked by visible tension between the two families.

Does anyone have information about Marcus’s activities that evening or the circumstances near Central Park at 8:20 p.m.?
