A fired Ohio State Highway Patrol trooper has pleaded not guilty after a Seneca County grand jury indicted him on a felony strangulation charge and added a domestic violence count, in a case stemming from an alleged assault on his girlfriend at their Tiffin home.

Nathaniel H. Cain, 23, entered not-guilty pleas to both counts at an arraignment on Thursday, June 18, before Seneca County Common Pleas Judge Damon D. Alt, court records show. His bond was continued at $75,000 with no 10 percent option, and the judge scheduled a pretrial hearing for Tuesday, July 28.

A grand jury returned the two-count indictment on Monday, June 8. Count one charges domestic violence under Ohio Revised Code 2919.25(A), a first-degree misdemeanor; count two charges strangulation under R.C. 2903.18(B)(2), a third-degree felony. Cain was originally charged by complaint in May with a single count of strangulation, and the domestic violence count was added through the indictment.

The charges stem from a May 19 incident at the home Cain shared with his girlfriend. According to a sworn complaint, she reported that Cain grabbed her jaw and squeezed, breaking one of her lower teeth, then grabbed her neck and squeezed for about seven seconds, leaving redness the responding officer documented. TiffinOhio.net is not naming the woman. The charge was first reported by TiffinOhio.net in June.

Cain has denied assaulting the woman. “I didn’t put my hands on her,” he told investigators, according to police records the department later released. Those records also detailed how officers took him into custody as he reported for his shift at the Patrol’s Norwalk Post.

The Highway Patrol fired Cain on June 4, 16 days after his arrest, citing conduct unbecoming an officer. Personnel records showed his supervisor had praised him as a model officer months before the charge.

Cain is represented by attorney Dean Henry. The case is being prosecuted by the office of Seneca County Prosecutor Derek W. DeVine and remains active.

A criminal charge is an allegation. Cain is presumed innocent unless and until he is convicted in court.
