Most of the sources say Eddie Lino was in on the Castellano hit. I tend to agree.
According to the feds, Lino was made in 1986 and became part of Angelo Ruggiero´s crew. I believe that the old John Gotti crew had split into two crews, Ruggiero taking care of one of them while Gene Gotti took care of the other.
Both Ruggiero and Gene Gotti got indicted for drugpeddeling but Ruggiero was eventually freed. During the mess, Lino functioned as the acting capo for the Ruggiero crew and became capo when John Gotti decided to put Ruggiero on the shelf.

Eddie Lino´s cousin (or was it his brother??), Frankie Lino, was a Bonanno capo at the time.
There is a photo of Eddie Lino slumped dead over the steering wheels of his car circulating the internet. But I can´t seem to find it right now.
