They couldn’t charge him with murder because the medical examiner said the first shots against the perp, which were justified, had already killed him.
So how can you get charged with “aggravated battery” for shooting a corpse? They could have charged him with unlawful discharge, or desecrating a corpse, but battery can only be committed against a living person, so I expect he will get off for this if he gets a decent lawyer.
Littering...maybe.
Yep. Reckless discharge of a firearm, abusing a corpse, but not aggravated battery.
Desecration of a corpse?
