The 22-year-old man accused of trying to assassinate Rep. Gabrielle Giffords in a deadly shooting rampage wrote "Die, " in a note found at his home, a sheriff's official told The Associated Press on Tuesday.
Investigators believe the handwritten message was a reference to Giffords, Pima County Chief Rick Kastigar said. The note was found in a safe alongside other ones, including "I planned ahead," "My assassination" and the name "Giffords."
The source also told Milton that investigators are looking into whether Loughner may have conducted surveillance on Giffords’ district office and campaign rallies.
