would'nt carmine sessa know something about it? but it makes sense greg had to kill him before he went to there boss and greg couldnt get permission to wack his brother cause it would look bad so he had to do a sneek job with guys from another family. what if the killers were all fbi informents that greg knew. a fbi infomant hit team. thats crazy. the guy philly paradiso wore a wire on gotti's friend tony roache 1 of the shooters of big paul got roache in a herion case which he got 20+yrs. philly paradiso has a brother micky boy who a captain in the gambino family today.but for greg to kill his own brother is nuts, but iguess in his head it was him or me.
