Last week’s blog met Judge Joseph Force Crater who disappeared without a trace in 1930. This week’s blog introduces “Dapper” Dan Hogan, the so-called “Irish Godfather” of St. Paul, Minnesota. Like the judge, Hogan’s case remains unsolved.
St. Paul the Gangland Haven
St. Paul in the early twentieth century was one of the most corrupt cities in America. When John O’Connor became Chief of Police in 1900, he instituted what became known as the O’Connor Layover Agreement. The system was straightforward. Criminals could hide out in St. Paul if they followed three simple rules. First, they had to check in with O’Connor’s representative when they got into town. Second, they had to pay a small bribe. And third, they were not to commit major crimes within the city during their stay.
O’Connor’s first contact man was William “Reddy” Griffin. When criminals came to town, they would “check in” with Griffin at the Savoy Hotel and pay the required bribe. Griffin was O’Connor’s “ambassador” until he died suddenly of a stroke in 1913.
The Layover Agreement made St. Paul one of the most crime-free cities in America—for a while. But surrounding cities and towns suffered as crooks committed the crimes the planned in St. Paul there.
Dan Hogan Arrives on the Scene
Dan Hogan arrived in St. Paul around 1908. He began organizing crimes under the auspices of O’Connor’s system and became politically connected. He operated the Green Lantern, a saloon on Wabasha Street. The saloon catered to the underworld element and laundered their stolen money. It also had a casino and, during Prohibition, was a speakeasy.
Hogan took advantage of William Griffin’s death to become O’Connor’s “ambassador” to the criminals seeking shelter in St. Paul. However, O’Connor retired from the police force in 1920. The O’Connor Layover Agreement persisted for several more years, but it began to change in ominous ways. St. Paul’s crime rate, which had been low while O’Connor was active, began to climb.
A Car Bomb Kills Dan Hogan
On December 4, 1928, Dan Hogan got into his Paige coupe and stepped on the starter. A nitroglycerine bomb wired to the starter circuit exploded. Men both respectable and disreputable lined up at the hospital to donate blood, but Hogan slipped into a coma and died about 9:00 p.m.
Hogan’s death marked the beginning of the end for the O’Connor Layover Agreement. The repeal of prohibition at the end of 1933 accelerated its decline. With prohibition gone, so were the profits from illegal liquor sales. Bootleggers turned to kidnapping for ransom. Once known for its lack of serious crime, St. Paul became infamous for its criminal activity. Thanks to a recently energized FBI and a crusading newspaper man, the O’Connor Layover Agreement finally ended in 1935.
The murder of Dan Hogan was an early instance of assassination by car bomb, a technique perfected in New York. Police never arrested anyone for the murder, and it remains officially unsolved. However, recently declassified FBI files reveal that the likely killer was Hogan’s underboss, Harry Sawyer.
