BENTON COUNTY, MN (WTAQ) - A woman accused of killing her lover in Wisconsin has admitted slaying her husband in Minnesota.

39-year-old Angelina O’Mara was in the fourth day of her Minnesota trial when she pleaded guilty Tuesday to her first-degree murder charge.

She admitted taking a .22-caliber rifle to James O’Mara’s apartment in Sauk Rapids Minnesota, and shooting him once in the head as he was lying on a couch. That happened October 28th of last year.

A few days later, police in far northern Wisconsin said the woman’s boyfriend, Michael Pies of Blaine Minnesota, was found shot to death at a motel room in Ashland.

Angelina O’Mara is scheduled to be sentenced December 21st in Benton County Minnesota for her husband’s murder.

Once that case is finalized, officials say she’ll face a first-degree intentional homicide charge in Ashland County in Pies’ death.
