This theory is often floated but nothing I see supports it
No purpose to establish an alibi because nobody would suspect him Whom did Roth have to answer to?
Hmmm...let's see:
Michael and Roth are in a big deal involving Roth's holdings in Havana...Johnny Ola meets with Michael at Anthony's party...Rocco and Neri are in that meeting, implying that Michael has included them in the deal...Roth invites Michael to Havana, promises to turn over his Havana operation to him....Michael is mysteriously killed on h is way from the Presidential New Year's Eve party to his hotel, meaning that Roth doesn't have to turn over anything to a dead man...including whatever the dead man promised Rocco and Neri...
...and they don't suspect Roth...and they don't come after him for what was promised to Michael???
