A teenager accused of killing her foster mother in November 2012 changed her plea to guilty in court Thursday.
Court officials say Sabrina Zunich, 19, will be sentenced Sept. 29.
Zunich was arrested immediately after the murder of Lisa Knoefel. She previously pleaded not guilty to all charges.
Zunich said it was Lisa's husband, Kevin Knoefel, who hatched the plan to kill his wife and collect $785,000 from various life insurance policies. She said she was following Kevin Knoefel’s plan when she stabbed Lisa Knoefel 178 times.
Prosecutors are recommending a minimum sentence of 30 years to life for Sabrina.
Earlier this month, Kevin Knoefel was sentenced to life in prison with the possibility of parole after 30 years in the case. He was also sentenced to 12 years for sexual battery charges. He was found guilty in June of 11 counts in the case.
