In January 2011, Jared Lee Loughner attended an event hosted by then-Congresswoman Gabrielle Giffords. With a crowd gathered around Giffords, Loughner pulled out a handgun and fired, killing six people and wounding 13 others, including critically injuring Giffords herself.
Before the shooting, Loughner had posted a series of YouTube videos. The clips, which feature texts and diagrams drawn up by Loughner, reveal the inner workings of Loughner's paranoid perspective. Obsessed with the English language, advocating a new system of currency and warning of mind control and brain washing, Loughner's rants are all over the map.
After being arrested for the shooting in Tuscon, Ariz., Loughner was diagnosed as a paranoid schizophrenic, which initially postponed his trial and sentencing. Last year, however, Loughner was finally sentenced to a term of life in prison without the possibility of parole.
