Tattaglia was the head of one of New York's Five Families, which bears his name. Although his primary business was prostitution, he was the first to support Virgil Sollozzo's heroin connection, and went to war with the Corleone family after they refused to lend their political and police protection to the enterprise. Tattaglia's family struck first, claiming the life of notorious enforcer Luca Brasi, but their further attacks floundered. Tattaglia was dealt a blow when the protracted and bloody conflict claimed the life of his son, Bruno, and when Vito Corleone recovered control of his family, after Vito's son, Sonny Corleone is murdered, the two agreed to a sitdown to negotiate an end to the struggle. However, Tattaglia tellingly insisted that Don Corleone guarantee not to break the peace. After conceding to his demands, Corleone realized that the lowly "pimp" had been the front for a plan masterminded by another don, Emilio Barzini, to bring down the Corleones, divide the spoils amongst the Five Families, and embrace the lucrative heroin trade unopposed. His death varies between the movie and the book. In the movie version, he was in bed with a prostitute when Rocco Lampone and another assassin, acting on the orders of Michael Corleone, burst in and murdered both of them with M3 submachine guns In the book, he is standing over a bed with a young girl laying on it when Rocco Lampone puts four bullets in his stomach.
