Jared Lee Loughner was up all night prior to gunning down 19 people — six fatally — outside an Arizona supermarket, taking several trips to the supermarket's shopping plaza in between checking in at an area hotel and visiting two Walmarts to buy ammunition, according to a timeline released Friday by the Pima County Sheriff's Office.
(Yes, I read the whole article; yes, one of the Walmarts did refuse to sell ammo to the nutter.)
