A New York woman who killed her former boyfriend and his new girlfriend in an attack at a northern New Jersey home has received consecutive life prison terms.

Monica Mogg also received consecutive terms of 10 years for armed burglary, five years for hindering prosecution and 18 months for stalking. The sentences were handed down Wednesday.

The 50-year-old Washingtonville resident pleaded guilty in June, admitting she spent days stalking 52-year-old Arthur Noeldechen in an attempt to get him alone. They had dated for 10 years.

Mogg entered the home of his new girlfriend, 42-year-old Jung Yi "Lillian" Kim, through an unlocked door in October 2012. Mogg fatally shot him with a rifle and then repeatedly stabbed her after they got into a fight.
