Ohio Rev. Code Ann. § 1533.121

Except as otherwise provided by division rule, the driver of every motor vehicle that has caused the death of a deer by striking the deer on a highway may take possession of the deer, provided that within twenty-four hours thereafter, the driver reports the accident to a wildlife officer or other law enforcement officer. The officer shall investigate, and, if the officer finds the death has been caused as alleged, the officer shall give a certificate for legal ownership of the deer to the driver. If the deer is unclaimed, the certificate for legal ownership may be given to a private or public institution or charity or to another person.
