Over the weekend, New Yorkers watched in horror as surveillance footage surfaced showing a young man brutally beating an 81-year-old Bronx grandfather last Thursday. On Sunday the NYPD arrested 20-year-old Cameron "BillyBam" Roebuck in relation to the attack (a tipster helped them out) and today we now know who is really to blame: Facebook. When Roebuck isn't busy with alleged criminal activities (he's been arrested six times since 2008 on charges ranging from assault to burglary) he is apparently an avid Facebook gamer. But unlike some state assemblymen, Roebuck's game of choice is Zygna's Cafe World.

And he really likes it! Ninety minutes before investigators say he viciously mugged Rodriguez for $30, for example, Roebuck was hard at work making chips and guacamole in the game, on his way towards becoming a "master chef." Further, in the hours before police found him hiding in a Bronx basement "he seemed more concerned with his Cafe World obligations of filling pastry panels and cooking pot roast than getting arrested." Seriously, his wall is all about the Cafe World.

Meanwhile, Roebuck has yet to lock down his Facebook page which means we've learned a lot about the young man this morning. Want to know about Cameron? "Im to real right ask ya shawty she kno lol," he says. His interests include "getting money" and from his photos it looks like he is quite good at rolling blunts. Also, on September 27 he was "going to start going to church....who komin wit me?"
