“Make sure he’s dead” turns self defense into murder.
I do not not know the nuances of Ohio law, but generally that is true only to the extent that the State can prove beyond reasonable doubt:
1. At a time when the deceased was not mortally wounded, he unequivocally ceased the behavior which had given rise to the lawful use of force,
2. The officer(s) you plan to charge with murder were consciously aware that the deceased no longer posed a threat,
3. The officer(s) you plan to charge with murder made a conscious decision to continue to shoot the deceased, knowing that they were not legally justified in doing so, and
4. The injuries inflicted by the officer(s) you plan to charge with murder caused the death of the deceased.
If you can cite Ohio case law that transmutes an injury to corpse into a murder, I would be glad to read it.
