“Dapper Dan” Hogan, a St. Paul, Minnesota saloonkeeper and mob boss, is killed on December 4, 1928 when someone plants a car bomb under the floorboards of his new Paige coupe. Doctors worked all day to save him–according to the Morning Tribune, “racketeers, police characters, and business men” queued up at the hospital to donate blood to their ailing friend–but Hogan slipped into a coma and died at around 9 p.m. His murder is still unsolved.
Hogan was a pillar of the Twin Cities underworld. His downtown saloon, the Green Lantern, catered to (and laundered the money of) bank robbers, bootleggers, safecrackers and all-around thugs. He was an expert at defusing petty arguments, keeping feuds from getting out of hand, and (the paper said) “keep[ing] the heat out of town,” which made him a friend to many lawbreakers and a valuable asset to people (like the crooked-but-well-meaning police chief) who were trying to keep Minneapolis and St. Paul from becoming as bloody and dangerous as Chicago.
Hogan and the police both worked to make sure that gangsters would be safe in the Twin Cities as long as they committed their most egregious crimes outside the city limits. If this position made him more friends than enemies–“his word was said to have been ‘as good as a gold bond,'” the paper said, and “to numbers of persons he was something of a Robin Hood”–it also angered many mobsters who resented his stranglehold on the city’s rackets. Police speculated that some of his own associates might have been responsible for his murder.
