"How did they get the PIN, though?"
The father's wallet was turned out, so he could have had it there, I'm sure lots of people do that, even though they tell you not to.
However, the reason there was so much money available to be stolen was because they were doing some kind of refinancing and all that money was in the checking account. It seems like MAYBE the tenant could have known about that. In any event these were not wealthy people, they probably didn't often have large amounts of money in their bank account, so to think the Islamofacists killed them, and the tenant just stumbles on the bodies, takes the ATM card (rather than calling the police to report the murders!) and lucks into tens of thousands of dollars, well, that seems a tad too complicated and co-incidental to me.
Good point. Also, many, many people use their birthday as their PIN number, even though you shouldn't do that either (I know I do). I'm not sure if New Jersey driver's licenses show a person's Date of Birth, but my Virginia driver's license sure does!

Yeah but he was an ex-con and a former tenant, so he would not call the cops because he'd know he'd be the first suspect. (which he was)
