[citation needed] In the 1960s, following Giancana's rise to the day-to-day "boss" position in the Outfit, Buccieri served as a top enforcer and personal hitman.
Buccieri, along with Jackie "The Lackey" Cerone, James "Turk" Torello, Samuel "Mad Sam" DeStefano and Dave Yaras participated in the infamous torture murder of loanshark William "Action" Jackson.
[citation needed] The Outfit suspected Jackson of stealing its money and working for the Federal Bureau of Investigation (FBI) as an informant.
The 300-pound Jackson was hung on a meat hook and tortured with ice picks, baseball bats, a blow torch and an electric cattle prod.
They suspected that the party was a front for a mob summit meeting in which Giancana officially took over the Outfit from Anthony Accardo,[citation needed] which might have been an erroneous thought at some level, because Giancana has just spent the previous 12 months in federal prison and got booted that year as The Outfit's top day-to-day boss after getting out of prison, taking over the top spot nine years earlier.
