Cause marino never reached out to anyone to kill gotti. I think casso leakd this out after he started cooperating trying to get gottis son and brother to whack marino. Same way sammy the bull says in his book i made a plan with frank locascio to kill gotti after the trial when were free. Sammy knew that put franks life even if in jail and his sons life in danger from gotti. Didnt jimmy brown go to the basement were casso was killing the kid for whatever reason. I bet casso hated marino.
