Tommy DeSimone was born on 24 May 1950 in Cambridge, Massachusetts, USA. He was married to Angela. He died on 14 January 1979 in New York City, New York, USA.
Although several Mafia sources have stated that DeSmone was murdered in early 1980 because he killed a Mafia boss without permission, and his wife reported him missing early in March of that year, his body was never found. He was declared legally dead in 1990.
