On this date in 1931 gangster brothers Al and Abe Wagner and their Brother in-law Harry Brown attended a supposed peace conference with rival gangsters at the Hatfield House Hotel in Manhattan. After a few hours of drinking and talking Abe left the room to make a phone call. While he was in the next room Al and Harry got into an argument with their rivals and bullets began to fly. Three of them slammed into Al's chest as another plowed into his head. Five found their mark in brother in-law Harry who managed to walk out of the Hotel and make his way to nearby Bellevue Hospital. Abe escaped unharmed.
