Photos: Isabella Guzman's insanity plea accepted for stabbing her mom 151 times

Last August, when eighteen-year-old Isabella Guzman was arrested for murder, an arrest affidavit on view below estimated that she'd stabbed her mom 79 times. But subsequent evaluation determined there were even more knife wounds -- 151 of them in all.

Now, however, a judge has accepted Guzman's not-guilty-by-reason-of-insanity plea in the same jurisdiction where prosecutors are continuing to seek the death penalty despite Aurora theater shooter James Holmes doing the same thing. See photos and a video and get more information about this shocking case below.
