Legal Question in Criminal Law in Ohio

Re: Sheriff's responsibility to the people in their home.

To the best of my knowledge, there is no state statute governing the conduct of a Sheriff placed in a situation you describe. The Sheriff is charged with the protection of citizens, including those who are a threat to themselves. It is likely there is a police dept. policy or regulation that gives guidance to the officer responding. I'd assume the Sheriff in that situation is told to not let the person injure themselves, to the extent of wounding them to prevent possible fatal self inflicted wounds. I hope that helps. If you need to know more, contact an attorney in your area. Good luck.
