N.H. Man Admits Killing Mont Vernon Mom

NASHUA, N.H. (AP) -- A New Hampshire man is admitting he hacked to death a mother and seriously wounded her young daughter, but he says he was insane when he did it.

In court Monday, 21-year-old Christopher Gribble of Brookline, NH waived his right to a jury trial on whether he killed 42-year-old Kimberly Cates and seriously wounded her 11-year-old daughter, Jaimie.

Gribble answered, "Yes your honor" when asked if he committed murder, attempted murder, conspiracy to commit murder and burglary and that he tampered with a witness. He then pleaded not guilty by reason of insanity to each charge.

The burden now shifts to Gribble's lawyers to prove he was insane during the October 2009 Mont Vernon home invasion. Gribble opted for a jury trial on the insanity claim.

It's scheduled for February.
