FOLEY -- A Cold Spring woman will be sentenced to life in prison this afternoon for murdering her ex-husband in October 2011.

39-year-old Angelina O'Mara pleaded guilty to first degree murder during her trial last month. She admitted she killed her ex-husband James O'Mara with a .22-caliber rifle. O'Mara says she brought the gun into James O'Mara's Sauk Rapids apartment the night of October 28th and shot him once in the head as he lay on the couch.

The guilty plea came about abruptly as O'Mara's trial was to enter the fourth day.

She'll be sentenced in Benton County District Court to life in prison without the possibility of parole.

O'Mara also faces a first-degree murder charge in Wisconsin in the death of her boyfriend, Michael Pies. Pies was found dead with a small caliber bullet wound to the head. It's unclear when that trial is expected to start.
