COLUMBUS, Ohio (AP) - Authorities have made an arrest in the gruesome death of a woman found covered in burns and suffering on the side of a rural Ohio road.

The Muskingum County Sheriff's Office said charges of aggravated murder, kidnapping and aggravated arson were filed Friday against 20-year-old Katrina Marie Culberson of Canton. It's unclear whether Culberson has an attorney.

A driver found 29-year-year-old Celeste Fronsman early Sunday on a road northeast of Zanesville. She had been raped and burned, and had a strap around her neck. She died two days later at a Columbus hospital.

The Franklin County coroner ruled the death a homicide but says it'll be four to six weeks before the exact cause of death can be determined because of how badly she was burned.
