PAINESVILLE, Ohio - A northeast Ohio teenager who killed her foster mother in 2012 at her foster father's urging has been sentenced to life in prison with a chance for parole in 30 years.

Sabrina Zunich, 19, pleaded guilty last month to aggravated murder in the stabbing death of 41-year-old Lisa Knoefel in their home in the Cleveland suburbs.

Zunich testified at the trial of Kevin Knoefel that he'd threatened suicide if his wife wasn't killed. Zunich and the now 44-year-old Kevin Knoefel were romantically involved.

Kevin Knoefel received the same sentence as Zunich after a jury found him guilty of conspiracy to commit aggravated murder and sexual battery. Prosecutors say Knoefel wanted his wife dead to collect $750,000 in life insurance.

Zunich said Monday at sentencing that she was remorseful.
