Robert Johnson, 35, was shot on July 14, 2013, on the 3400 block of Fremont Avenue North in Minneapolis and died after surgery at North Memorial Medical Center at 6:23 a.m. The Hennepin County Medical Examiner’s Office determined the cause of death was gunshot wounds to the chest and abdomen.

Police say the shooting arose from an argument and that Johnson knew his assailant; the suspect fled on foot into the morning. At the time police issued appeals to the public and were interviewing witnesses to reconstruct what happened.

If anyone has information about Johnson, the encounter on Fremont Avenue North, or the person who fled that morning, please share what is known with investigators.
