PHOENIX (AP) - An Arizona sheriff says a 22-year-old man accused of killing six people and trying to assassinate Rep. Gabrielle Giffords in Tucson is not cooperating with investigators.
Pima (PEE'-muh) County Sheriff Clarence Dupnik told ABC's "Good Morning America" Monday that Jared Loughner (LAWF'-nuhr) had said "not a word."
He's scheduled to make his first court appearance Monday afternoon.
Dupnik said investigators were all but certain Loughner acted alone, saying "he's a typical troubled individual who's a loner."
The sheriff said his earlier comments blaming political discourse for the shooting were the result of his anger about the shooting - not any agenda.
