Jared Lee Loughner is a 22-year-old "ardent atheist" and a left-wing nihilist. He was formally charged with a shooting spree on January 8, 2011 that left 6 dead and 14 injured, including congresswoman Gabrielle Giffords. He may have been on drugs, and has been described by former public school classmates as a "pothead".
Jared Loughner was also a "big video gamer" who "spent most of his time playing video games and listening to heavy metal music like 'Drowning Pool.'"
Jared Loughner would reportedly say to friends:
|“||I'm pretty sure I've come to the conclusion that words mean nothing.||”|
|“||Life 'means nothing.'||”|
Jared Loughner "talked about reading Friedrich Nietzsche’s book The Will To Power and embraced ideas about the corrosive, destructive effects of nihilism — a belief in nothing. ... Neighbors ... would not chase after a ball that landed in the Loughners' backyard. 'They had to buy a new one.'"
Jared Loughner mocked an Army policy of distributing mini-Bibles to new recruits. He publicly listed The Communist Manifesto, Mein Kampf and We the Living by Ayn Rand as some of his favorite books. Loughner had a occult shrine in his backyard and was obsessed with the occult and mind control.  Throughout Loughner's attendence at his public high school, it was part of a network called Small Schools Workshop, which was founded by communist and terrorist Bill Ayers and funded in the 1990s by Barack Obama.
Loughner failed a urine drug test when he applied to join the U.S. Army, and was rejected for that reason. But as of January 10, 2011, there has been no release of any drug tests performed on Loughner following the shooting. Arizona recently passed a law legalizing medical marijuana. His close friend claimed that Loughner has been drug-free since 2008, but his late-night postings on video game forums within the last year were suggestive of drug use. Friends say he believed the United States was responsible for the 9/11 terrorist attacks.
