In 1947, the crime families ordered the murder of Siegel due to his mismanagement of the Flamingo Hotel, most likely because Siegel or his girlfriend Virginia Hill was skimming money. According to one account which does not appear in newspapers, Cohen reacted violently to Siegel's murder. Entering the Hotel Roosevelt, where he believed the killers were staying, Cohen fired rounds from his two .45 caliber semi-automatic handguns into the lobby ceiling and demanded that the assassins meet him outside in 10 minutes. However, no one appeared, and Cohen was forced to flee when the police arrived.
