Who Is Jared Lee Loughner?

The 22-year-old Arizona shooting suspect is already the subject of great controversy—and not just because of his alleged crimes. Loughner's purported history of outbursts, drug problems and early-warning signs mixed with his radical political views have all sides of the spectrum distancing themselves. Friends and acquaintances were quick in telling the press about the many disturbing personality traits Loughner had long displayed. High school friends noted he was forever embarrassed—even traumatized—after a bout of alcohol poisoning. College classmates pointed to "nonsensical outbursts" and "inappropriate laughter" and vicious criticism for stories about real-life abortions. But none of these warning signs pointed to unspeakable violence. Until January 8, 2011.
