A woman has pleaded guilty in New Jersey to paying an undercover police officer she thought was a hit man to kill her daughter's ex-boyfriend by burning him alive.

Acting Attorney General John Hoffman says Denise Nagrodski pleaded guilty Thursday to attempted murder and conspiracy to commit murder.

The state will recommended the 52-year-old Easton, Pennsylvania, resident be sentenced to 10 years in prison under the terms of the plea agreement. She'll be sentenced in October.

Hoffman says Nagrodski claimed the ex-boyfriend was abusive and caused her daughter to have a miscarriage years ago when she was pregnant with twins.

Nagrodski told the detective to burn him alive and make sure he knew she was responsible. She also wanted to kill two other people who lived with him in Somerset County.

No one was harmed.
