Randolph Ramon Miggins, 30, was fatally shot shortly before 2 a.m. on Monday, June 18, 2012, after an altercation that began inside Mai Tai’s nightclub on 8 Mile Road in Detroit and spilled outside as people were leaving. Two other people—a 25-year-old woman and a 39-year-old man—sustained nonfatal injuries in the same outbreak of gunfire.

Initial accounts conflicted about who fired the fatal shots: a relative of Miggins said a bouncer shot him, while club security suggested the shooter was someone who had been with Miggins. The Detroit Police Department released a surveillance photo of a man in a baseball cap as a person of interest and asked for public help. No arrests or charges have been publicly announced, and the case has gone cold, leaving the shooter’s identity and the motive unresolved.

If anyone was at Mai Tai’s that night or has information about the man in the baseball cap, please share what is known with Detroit investigators.
