A Huron County man has been sentenced to prison in the long-unsolved death and disappearance of Amanda Dean, a mother of four who vanished in 2017.

Ohio Attorney General Dave Yost announced that Frederick Reer, 42, of Townsend Township, was sentenced to 14 years in prison.

Reer pleaded guilty in December to involuntary manslaughter, two counts of tampering with evidence, and gross abuse of a corpse. He was indicted in February 2024 following an investigation that determined Dean was killed inside the home the couple shared in Townsend Township, near Norwalk.

Court records say Reer then attempted to conceal the crime by destroying and disposing of evidence, and Dean’s body has never been recovered.

Dean was last seen on July 11, 2017. The case remained unsolved for nearly eight years before investigators with the Ohio Bureau of Criminal Investigation brought the case forward.

BCI led the investigation at the request of the Huron County Sheriff’s Office, with prosecutors from the Ohio Attorney General’s Office assisting the Huron County Prosecutor.

Attorney General Dave Yost said the sentence brings accountability in a case that deeply affected the community, while acknowledging the long wait for answers endured by Dean’s family.
