Keon Jamall Washington was 17 when he was shot and killed outside a house party on the 500 block of Madison Street in Ypsilanti. The shooting occurred in the early morning hours of June 27, 2014, after an argument between members of two rival street cliques erupted into gunfire. Keon was struck in the head and found in the street by police.

Investigators tied the incident to escalating gang violence between groups identified as BOH and Rakk Life. A 19-year-old, Keandre Duff, was later charged with attempted murder, carrying a concealed weapon, and possessing a firearm during the commission of a felony, though authorities said they did not believe Duff fired the fatal shot. A 17-year-old initially detained was released. The charges against Duff were eventually dropped for insufficient evidence and the case went cold.

Keandre Duff was himself killed on July 12, 2015, in what police suspected was retaliation for Keon’s death. No one has been convicted for Keon Jamall Washington’s murder. Does anyone have information that could help bring Keon’s killer to justice?
