RPT-Arizona suspect had made death threats-sheriff
Roger Whithed, 52, a construction worker who lives two doors down from Loughner, said of the suspect: "He was a kind of on-the-edge of society type guy, blue jeans, baseball cap, one of those guys who hasn't really figured it out. A little rebellious looking, didn't look like he was working really or doing anything productive," he said.
Grant Wiens, 22, was a year ahead of Loughner at Mountain View High School in Tucson, and was recently in a biology class with him at a local community college. He remembers Loughner smoked heavily and occasionally smoked marijuana.
"You never expect this to happen, regardless of how well you know someone. I think I would have said he would have been more likely to do it than some people, just a gut instinct," he said.
"There was something about his personality, but nothing I can put my finger on. ... He was smart, opinionated, but maybe a little troubled."
Wiens said he never mentioned Giffords, guns or politics. "He was opinionated, though he got along with people, he never seemed to care what people thought."
