Case History
Pinpointing the precise moment a mental illness takes root is guesswork at best. As a young man, Loughner seemed ordinary enough — occasionally withdrawn, as all teens can be, and a little nerdy.

But a darkness began massing around Loughner sometime after he dropped out of Mountain View High School in Tucson, Ariz., before his senior year. He started drinking a lot, according to Kylie Smith, who had known him since preschool. She lost contact with him between 2006 and 2008 and was stunned by how much he had changed. "He seemed out of it, like he was somewhere else," she says. "I could tell he wasn't just drunk and he wasn't just high."
Was a psychiatric illness beginning? Maybe, but it's difficult to tell, because Loughner had by then used a lot of drugs — not just pot but also hallucinogens like acid, according to Smith.
