The man identified by authorities as the gunman in Saturday's shooting rampage, which killed six and critically injured Rep. Gabrielle Giffords, D-Ariz., appears to have left a trail of bizarre and anti-government messages on the Internet.
Law enforcement sources identified the gunman as Jared Lee Loughner, 22, of Tucson. Loughner, or someone using his name, left a series of postings and homemade videos that laid out a fervent, though largely incoherent, set of political views.
On YouTube, Loughner's profile listed Karl Marx and Friedrich Engels's The Communist Manifesto and Adolf Hitler's Mein Kampf among his favorite books. He also included high school English class classics such as To Kill a Mockingbird and The Old Man and the Sea, plus children's works such as Aesop's fables and The Phantom Tollbooth.
In one video, titled "America: Your last memory in a terrorist country!," a figure in dark clothing and a smiley-face mask burns an American flag in the desert. The soundtrack is a 2001 song by the band Drowning Pool, in which the singer repeatedly shrieks "Let the bodies hit the floor!"
Never miss a local story.
Another, posted Dec. 15, begins with a line of text reading "My Final Thoughts: Jared Lee Loughner!" What follows on the screen are seemingly unconnected thoughts about currency and dreams, and the words "I can't trust the current government because of the ratifications: the government is implying mind control and brainwash on the people by controlling grammar."
The videos also say that Loughner applied to join the U.S. Army. The Army issued a statement Saturday saying he attempted to enlist but was rejected for reasons that officials would not disclose.
Another video attacks the police at Tucson's Pima Community College, where he had been a student.
School officials said in a statement late Saturday that Loughner attended the community college from 2005 until last fall, when he withdrew after disciplinary problems.
On Sept. 29, the college said, it discovered Loughner had posted a YouTube video he had made claiming "the college is illegal according to the U.S. Constitution."
That day, two police officers delivered a letter of suspension to Loughner at his parents' house in a Tucson suburb.
On Oct. 4, during a meeting between Loughner, his parents and college administrators, he agreed to withdraw, the college said. School officials told him he could return only if he obtained a clearance certifying that "in the opinion of a mental health professional, his presence at the college does not present a danger to himself or others."
