Celeste E. Fronsman was left for dead in a secluded part of Muskingum County, an hour from her Canton home.

Her alleged killer lived just across town.

On Friday, authorities in Zanesville charged Katrina M. Culberson, 20, of 424 17th St. SE, with aggravated murder, kidnapping and aggravated arson in connection with Fronsman's death.

Canton police and Muskingum County Sheriff's deputies arrested Culberson Wednesday on an unrelated theft warrant.

Sheriff Matthew Lutz wouldn't comment on whether Culberson is alleged to have acted alone, nor would he discuss who Fronsman was with or where she was before her death.

James Fronsman said his 29-year-old daughter left in his pickup with a girlfriend around 6 a.m. Aug. 24 and never returned. The truck was found parked at McDonald's at 112 Dueber Ave. SW.

On Sunday morning, a passerby called 911 after finding Fronsman naked, beaten and severely burned. She died Tuesday at a Columbus hospital.

Franklin County Coroner Dr. Jan Gorniak has ruled Fronsman's death a homicide but hasn't determined the cause. The coroner said Fronsman had burns over three-fourths of her body.

Earlier reports said Fronsman was raped. Lutz wouldn't release any information regarding that allegation, but rape is not one of the charges against Culberson.

Culberson and Fronsman knew each other but the sheriff wouldn't discuss their relationship or a possible motive, saying only, "This wasn't random."

Investigators are trying to contact other "people of interest," the sheriff said.

Local court records show that Culberson has been convicted of several misdemeanors, including criminal trespass, soliciting for prostitution and obstructing official business since 2010.

The theft warrant accuses her of stealing a purse from a disabled woman at a Walmart store earlier this month.

Fronsman also had a lengthy criminal record, including convictions for soliciting for prostitution.
