It was decided by the Feds that DeLuca wasn't needed for the Bulger trial, as Weeks and Flemmi did plenty of damage. DeLuca has been an informant for over a decade and he gave up the strip club racket, the Big Dig extortion racket and all illegal gambling in Rhode Island and Boston. His secret testimony and information pipeline led to the arrests of Peter Limone, Carmen & Anthony DiNunzio, Mark Rossetti, Darin Bufalino, Anthony St. Laurent, Luigi Manocchio, Eddy Lato and all others connected to the strip club operation. If you remember, St. Laurent has been accusing him of being an informant for at least a decade and was seeking permission to whack DeLuca, but Baby Shacks and other high ranking members thought the Saint was delusional and on drugs...turned out he was spot on the entire time. New England is as good as toast, they are on life support.
