Marcus J Heilderberg, 23, was shot and killed in downtown Kansas City outside the Retro nightclub in the 1500 block of McGee Street during the early morning of May 19, 2012. A dispute inside the club began when a man demanded an apology from one of Heilderberg’s relatives; that relative refused, believing he had been mistaken for someone else. The confrontation escalated, lights were turned on and the bar closed early, and the conflict carried outside where several fights broke out.

Witnesses say Heilderberg intervened to separate his brother from another person and was acting as a peacemaker when he was struck by gunfire. He was taken to a hospital and later died of his injuries. The Kansas City Police Department opened an investigation under report number 12-34340; despite witnesses and the incident occurring in public, the case remains unsolved and no suspects have been publicly named or charged. A reward has been offered for information leading to an arrest.

If anyone was in or near Retro on McGee Street that night and remembers details about who left the scene or who was involved in the fights, please come forward with what was seen.
