Holmes May Plead Insanity for Aurora Shootings

You mean he hasn't already?

James Holmes, the University of Colorado doctoral program dropout charged with killing 12 and injuring or wounding nearly 60 others during a July 20 shooting spree, may use an insanity defense.

Holmes' court-appointed public defenders indicated that Holmes might plead not guility by reason of insanity at his arraignment hearing, scheduled for March 12. Holmes, 25, faces more than 140 charges of first-degree murder and attempted first degree murder.

The move isn't unexpected. Holmes' attorneys have indicated that he suffers from mental illness at several prior court appearances, and a University of Colorado psychiatrist has testified that she saw Holmes before he dropped out of school in June.
