On Sunday, a search party looking for Ratliff called the sheriff’s office to report that they found a dead female matching the 20-year-old’s description in a vacant residence in the 1800 block of Chestnut Street, investigators said. Officials identified the body as Ratliff.

Coshocton County Coroner Douglas Virostko confirmed to the Coshocton Tribune that Ratliff suffered a traumatic death but said he could not elaborate due to the ongoing investigation.

No further details on Ratliff's death were immediately released.

The sheriff's office said more charges were expected against Grewell as the Coshocton County Prosecutor’s Office continues to review the case.
