A former corrections officer was convicted Tuesday after an inmate at a Lebanon prison was assaulted last September, according to a press release from the Warren County Prosecutor's Office.

John Hinkle, 52, of Trenton, Ohio, was found guilty on two counts of felonious assault after an incident took place at the Lebanon Correctional Institution on Sept. 16, 2018.

According to the release, Hinkle used a PR-24 baton and struck the inmate in the face while the inmate was kneeling and handcuffed behind his back.

The inmate suffered a broken jaw which required surgery, the release states. The inmate's jaw was wired shut for six weeks due to the injury.

“The corrections officers in our state and our county face verbal and physical abuse from inmates on an almost daily basis. They are required to maintain order when inmates create chaos," said Warren County Prosecutor David P. Fornshell. "The overwhelming majority of these corrections officers do their jobs in an extraordinarily professional manner. But despite the challenging environment in which they work, they are not above the law. They cannot use deadly force against an inmate when it is not justified.”

Hinkle has not yet been sentenced.
