SACRAMENTO, Calif. (AP) — The FBI said Friday it found a martyrdom letter and several guns in the home of a former Marine who said he wanted to carry out a Christmas Day attack on San Francisco’s Pier 39, a popular tourist destination. Everitt Aaron Jameson, 26, a Modesto tow-truck driver, was charged Friday with attempting to provide material support to a foreign terrorist organization. Jameson told an undercover agent he believed to be associated with senior leadership of the Islamic State group that he wanted to conduct a violent attack on Pier 39, which is packed with restaurants, bars and souvenir shops, because it is heavily crowded, according to an FBI affidavit.
