Keith Mederick Parker was 38 when he was fatally shot on the evening of Tuesday, September 27, 2011, in the 4000 block of Primrose Avenue in Baltimore. The killing took place during a year the city saw a high number of homicides and frequent street violence tied to disputes and turf conflicts.

The Baltimore Police Department investigated, but detectives encountered a lack of cooperating witnesses and no significant leads were made public. No suspect or arrest has been announced, and the trail went cold as the initial canvass and activity petered out.

For family and friends, the absence of answers has left an enduring void. Does anyone who lived on or near Primrose Avenue in late September 2011 recall anything that might help solve Keith Parker’s murder?
