January 26, 2011 Tucson Suspect Studied Assassins, Officials Say By JOSEPH GOLDSTEIN and MARC LACEY TUCSON Jared L. Loughner, the man accused of opening fire outside a Tucson supermarket on Jan. 8 in what the authorities consider an attempted political assassination, researched famous assassins, the death penalty and solitary confinement on the Internet before the shooting, an official close to the investigation said Wednesday. Mr. Loughner, 22, pleaded not guilty on Monday to three counts of attempted murder in connection with the shooting, which left six people dead and 13 injured. Representative Gabrielle Giffords, Democrat of Arizona, was shot in the head but survived. Additional charges, including murder, are expected. Mr. Loughner checked himself into a Motel 6 on the evening before the attacks and was on his computer until the wee hours, authorities said. An analysis of his Web searches showed that he was busy researching hours before the shooting, which took place shortly after 10 a.m., an official said. He was looking at Web sites related to lethal injection and Web sites about famous assassinations, said an official close to the investigation. The Washington Post first reported the Internet searches on its Web site on Wednesday afternoon.
