TUCSON, Jan. 26 (UPI) -- Tucson shooting spree suspect Jared Loughner went online to research lethal injection, solitary confinement and political killings, investigators say.
The 22-year-old college dropout's computer was seized immediately after his arrest at the Jan. 8 rampage that left six people, including a federal judge, dead and 13 others, including Rep. Gabrielle Giffords, D-Ariz., wounded, The Washington Post reported. The newspaper cited law enforcement sources who said investigators tracked the Web sites Loughner visited in the weeks before the massacre in a supermarket parking lot.
