Matthew Deon Johnson was 22 when he was shot in the head near an apartment building in north Minneapolis on June 11, 2010. He was taken to a hospital and later pronounced dead. The shooting occurred during a violent span in the city when several homicides happened in quick succession.

Minneapolis police investigated Johnson’s death alongside the other recent killings. Deputy Chief Rob Allen said the victims, including Johnson, were known to the department, which the police noted improves clearance prospects when victims and suspects have prior contact. Authorities did not release a motive or suspect descriptions and no arrests were announced at the time; the investigation remained active.

If anyone knew Matthew, saw activity near that apartment building that day, or has information that could help the ongoing investigation, please come forward.
