Aladena Jimmy the Weasel Fratianno (November 14 1913 – June 30 1993) was an Italian-born American mobster based in Cleveland Ohio and later acting head of the Los Angeles crime family before becoming a US government witness. Fratianno was the most powerful mobster to become a federal witness until Sammy the Bull Gravano agreed to testify against the Gambino crime family in 1991.
