From what I understand, they left that kid alone for days. They'd leave him money and he would be on his own at 12/13/14 years old. He'd ask neighbors to drive him to the store. I am not sure if they even checked in on him.
But the one thing out of all of this, already knowing these people are just absolutely horrible parents was that when their son got arrested, they chose to flee the country instead of being there to help him. These people make me sick, but I think they'll get away with it. If Casey Anthony can get away with what she did, then these disgusting pieces of filth can too - and they'd be lauded as 2nd Amendment heroes. No, not in Oxford, but in much of this country. They'll just blame Gretchen.
