Yaras was involved with the Teamsters union, helping to organize the branch Local 320 in Miami. Santo Trafficante Jr. used Local 320 as a front for his activities. It was occasionally used as his headquarters and facilitated narcotics trafficking by providing trucks for transportation. Yaras and Trafficante dined and drank together. He functioned as a go-between for Trafficante and Carlos Marcello in New Orleans. He also served as a liaison between Chicago and organized crime in Miami and briefly was a mentor to Frank Rosenthal.The Kefauver Committee of the US Senate determined that Yaras was a hitman for Sam Giancana and was involved in the slot machine and pinball business of Al Capone. He was also of interest to the McClellan Committee, with Senator Bobby Kennedy describing Yaras as "a notorious Chicago racketeer who has been involved with many of the leading racketeers in the Midwest".
Yaras's partner in crime was his fellow Jewish Chicagoan, Leonard Patrick. They were particularly close, so much so that Yaras named one of his sons after Patrick. Lenny Yaras would go on to become one of Patrick's lieutenants. On 14 January 1944 Benjamin "Zukie the Bookie" Zuckerman, the boss of an independent gang in Lawndale, Chicago was murdered, with Yaras and Patrick considered the likely culprits. On 8 March 1947 Yaras, Leonard Patrick and William Block were indicted on the charge of murdering James Ragen. Although on 3 April 1947 the indictment was dropped after one of the three witnesses was murdered and the two others refused to testify. While in Miami in January 1962, Yaras was recorded by the FBI in an electronic eavesdropping operation discussing the proposed killing of Frank Esposito with his fellow mobsters Jackie Cerone, Fiore Buccieri and Jimmy Torello. The Florida authorities were subsequently tipped off. Yaras and Patrick were suspects in the murder of Alderman Benjamin F. Lewis in February 1963, after the FBI received a tip from an informant that the duo had killed Lewis. However neither were charged and the murder remains unsolved to this day.
