Alberto Falcone, also known as the serial killer the Holiday Killer, is said to be based on Fredo Corleone of the Godfather series and was featured in Jeph Loeb and Tim Sale series' "Batman: The Long Halloween" and "Batman: Dark Victory".
This news meshes with a previous quote from Gary Oldman talking about the story saying, "It's the scope of it and the way [Christopher Nolan] sort of brings it back to Batman Begins. And really what Bruce Wayne discovers about himself and what he learns about himself by the end of this one."
