(AP Photo/Bill Robles) His mugshot might have the look of a crazy man, but Jared Lee Loughner apparently knew full well what was in store for him after the Tucson shooting spree he stands charged in. In the weeks before the attack, Loughner used his computer to look up the subjects of lethal injection and solitary confinement, sources tell the Washington Post. He also studied up on political assassins. "The impression investigators have is that he was trying to educate himself on assassinations and also research the consequences," one source tells the paper. Prosecutors will use the information in their attempt to prove that Loughner is sane and knows the difference between right and wrong. Read These Next One wrong step costs teen at Yellowstone.
