That's a true story, BK. The story was that Marcello had a phony Guatemalan passport to cover up with, so Bobby had him "deported" to Guatemala, and yes, he was left in the middle of a jungle. He managed to get to Nicaragua, but the Justice Dept. leaned on them there and he was once again stranded--apparently left to die. Marcello managed to get back after about three weeks. Showed incredible resourcefulness.
And let me chime in on SC's "half brother":

Ntra la porta tua lu sangu � sparsu,
E nun me mporta si ce muoru accisu...
E s'iddu muoru e vaju mparadisu
Si nun ce truovo a ttia, mancu ce trasu.
