Supposedly he was part of the McBratney killing but he didn't pull the trigger. Other than that there's no proof he took part in a murder other than that there's only rumours of what happened to DeSimeone and Favara.
Massino did name him as the Vito Borelli triggerman IIRC. An then there's whatever happened to that codefendant of Dellacroce who disappeared in Florida.
I'd take what massino says with a grain of salt. Also i think massino meant taht gotti set up the murder and didnt actually kill him himself. The co-defendent in Florida was Tony Plate who even at age 66 was regarded as a psychopath. I've heard that gotti ordered wilie boy and angelo to take care of plate
