In perhaps the most infamous event of the Capone era, the mobster's henchmen, dressed as cops, lined up seven members of Bugs Moran's gang against the garage wall that used to stand here and sprayed them with bullets. After that, Moran cut his losses and Al Capone gained control of Chicago’s North Side vice. The garage was torn down in 1967 to make way for a retirement home.
The facility’s landscaped parking lot now lies at the site. A house (2119 N Clark St) used as a lookout by the killers stands across the street.
