Michael left his Tahoe estate shortly after the shooting. He told Tom before he left that the shooters were killed by "someone close to us, inside...very scary." He also told Tom, in effect, that he couldn't completely rule out Rocco and Neri.

Why would Michael leave his wife and kids at the estate while a traitor--"someone close to us, inside"--was still at large?

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.
