NEW CASTLE, Pa. (AP) _ A woman found dead along a rural western Pennsylvania road was the ex-wife of a doctor imprisoned for writing illegal painkiller prescriptions to his patients.

Lawrence County Coroner Russell Noga says autopsy results on 40-year-old Kristiana Wilkins were inconclusive, pending toxicology tests that will take weeks to complete.

State police say the woman's body was found 5 p.m. Wednesday along County Line Road in Shenango Township.

That's near New Castle, about 45 miles northwest of Pittsburgh.

A township police officer discovered the body when he arrived at the scene to help a stranded motorist.

The woman's ex-husband, a chiropractor named Thomas Wilkins, was sentenced to seven to 15 years in prison in 2006 for writing unnecessary prescriptions and Medicaid fraud.
