Congress on Your Corner – that was what Gabrielle Giffords had set up outside a Tucson Safeway in an attempt to meet and greet the citizens of the Arizona city. Tonight, federal murder charges have been filed against Jared Loughner, the 24-year-old who shot Giffords in the head, then fired round after round into the crowd surrounding her table, killing six others and injuring twelve.

Now more details are coming out about the disturbed young gunman. The Washington Post reports that neighbors and former classmates described Loughner and his parents as loners who rarely interacted with people, and never interacting with their neighbors.

“You try to say something, they’d just ignore you and turn around and walk back into the house,” said Ron Johnson, 60. “The kid – I never talked to him. He acted just like his parents and ignored you.”

Loughner’s parents are Randy Loughner and Amy Loughner. They live in a modest ranch home in Tuscon and have a dog.
