Clifford Johnson, a 58-year-old Black man from College Park, was fatally stabbed in northwest Atlanta on June 10, 2014. The attack happened in the 500 block of Griffin Street; emergency crews found him in front of the Neighborhood Grocery and took him to Grady Hospital, where he died later that day from a single stab wound to the neck.

Initial Atlanta Police Department reports identified Johnson and the basic circumstances of the fatal encounter.

Does anyone have information about Clifford Johnson, his activities that day, or the 500 block of Griffin Street in June 2014 that could help advance this investigation?
