Another scene i never quite understood in Godfather part 2, was the scene in the hotel Fredo run, where the Senator wakes up with the dead girl(who im assuming is a hooker right) ?

Did i miss something here, or was there an explanation ? Was it a setup from Michael to get the senator in his pocket ?

How did the girl die ?

You guys are a wealth of interpretation, so i look forward to the posts once again.

cheers
