TUCSON, Ariz. (CBS/AP) Investigators in the Arizona shooting rampage that left six people dead and 14 others wounded, including Rep. Gabrielle Giffords, said they seized evidence suggesting suspect Jared Loughner planned ahead.
Investigators carried out a search warrant at Loughner's home and seized an envelope from a safe with messages such as "I planned ahead," "My assassination," and the name "Giffords" next to what appears to be the man's signature.
The FBI also found a letter in a safe from Giffords, on Congressional stationery, dated Aug. 30, 2007 that thanked Loughner for attending a "Congress on your Corner" event at the Foothills Mall in Tucson.
Loughner is charged with one count of attempted assassination of a member of Congress, two counts of killing an employee of the federal government and two counts of attempting to killing a federal employee.
Loughner remains in federal custody and is being transported to Phoenix where he will make an initial court appearance on Monday at 2 p.m. local time.
Loughner is accused of killing six people, including a federal judge, an aide to Giffords and a 9-year-old girl who was born on Sept. 11, 2001. Fourteen others were wounded, including the three-term Democrat lawmaker. Police don't know his motive, but said he targeted Giffords at a public gathering around 10 a.m. Saturday.
