Anthony Salvatore Casso, nicknamed "Gaspipe", was an American mobster and underboss of the Lucchese crime family. During his career in organized crime, he was regarded as a "homicidal maniac" in the Italian-American Mafia. Casso is suspected of having committed dozens of murders, and had confessed to involvement in between 15 and 36 murders.

The Lucchese crime family is an Italian-American Mafia crime family and one of the "Five Families" that dominate organized crime activities in New York City, within the nationwide criminal phenomenon known as the American Mafia. Members refer to the organization as the Lucchese borgata; borgata is Mafia slang for criminal gang, which itself was derived from a Sicilian word meaning close-knit community. The members of other crime families sometimes refer to Lucchese family members as "Lukes".
