The Tanglewood Boys are an Italian-American gang from Yonkers, New York, USA. They are named after the shopping mall that they frequent, located on a busy shopping strip, Central Avenue, in Yonkers. They have been around since the 1970s, as a "starter gang" or recruitment for the Italian Mafia, specifically the Lucchese crime family. The Quattrocchi crime family of North Jersey has also picked up associates from the Tanglewood Boys. However, the Quattrocchi family usually stays within its own family system of sons, brothers and cousins. Several members have gone on to other crime families as well, and they are usually the sons of "mafiosi." Famous members include Salvatore LoCascio of Eastchester Pasquale Perello, Jr. and Salvatore Quattrocchi, [of the North Jersey clan].
The Boys made the news in the late '90s, when their ranks were arrested for the murder of college student Louis Balancio at a Yonkers sports bar in 1994, and the subsequent cover-up by one of their mob fathers; one member, Darin Mazzarella, became an informant, resulting in the conviction of Anthony DiSimone on charges of second-degree murder in December of 2005.
A two-episode arc of CSI: NY featured a fictional representation of the group. The arc began in the first season episode "Tanglewood" and concluded in the season two episode "Run Silent, Run Deep."
