CNN says he was charged with Murder and Manslaughter. What level of Murder did they charge him with, or does Ohio not do that? Also, can you be found guilty of both Murder and Manslaughter, or is it likely the jury chooses one at the trial?
Ohio has Aggravated Murder, Murder, Voluntary Manslaughter and Involuntary Manslaughter:
http://codes.ohio.gov/orc/2903 If I had to guess, he was charged with Murder and Voluntary Manslaughter, based upon their definitions in the code.
You cannot be convicted of both murder and manslaughter for the same homicide, as the intent element of each is different. Murder, here, is
purposely causing the death of another
without immediate provocation, while voluntary manslaughter is
knowingly causing the death of another "while under the influence of
sudden passion or in a sudden fit of rage, either of which is
brought on by serious provocation occasioned by the victim that is reasonably sufficient to incite the person into using deadly force." With voluntary manslaughter, the severity of the offense is lessened because the perpetrator's actions were incited in some way by the victim. With murder, however, there is provocation to mitigate the perpetrator's actions. So, in Ohio, you either have provocation, and it's voluntary manslaughter, or you don't, and it's murder. You can't have it both ways.
Now the State can charge both murder and manslaughter and it can try to prove both in its case, but the jury can only convict on one.
