Little information is known immediately about Laughner — such as his background or a possible motive in the attack.
U.S. officials who provided his name to the AP spoke on condition of anonymity because they were not authorized to release it publicly.
Jared Laughner, the man who shot Congresswoman Gabrielle Giffords (D-Ariz.), was described by eyewitnesses as a young white man who looked like a "fringe character."
Laughner shot Giffords and 12 others at a public event at a Safeway grocery store in Tucscon. He reportedly shot the congresswoman "point blank" in the head and may have come from inside the store. After shooting Giffords, he allegedly fired 20-30 rounds and hit "a number of people," including a child. He attempted to flee after running out of ammunition and was tackled by one of Giffords' staffers.
Eyewitnesses have described Laughner as "young, mid-to-late 20s, white, clean-shaven with short hair and wearing dark clothing."
He was arrested upon arrival of the sheriff's department. (Source)
