Case in Giffords Shooting Likely to Take Years

TUCSON, Ariz. (AP) — Investigators have been poring over surveillance video, interviewing witnesses and analyzing items seized from Jared Loughner's home as they build a case in the assassination attempt against Rep. Gabrielle Giffords.

It's a case that likely will take years to play out as it goes through phases of the criminal justice system: prosecutions by both federal and state authorities, proceedings over whether to move the case to a different venue, a possible insanity defense by Loughner and prosecutors' likely push for the death penalty.

The next step is an arraignment scheduled Monday afternoon in Phoenix for Loughner, who is accused of opening fire on a Giffords political event in a rampage that wounded 13 people and killed six others.
