I would think they will do a tox screen if there's enough tissue left from which they can do it.
Don't they usually do this with blood? I doubt there's any blood left. :thinking: :dunno:
Seems as though they can use blood, urine, hair, bile, and a couple more methods, if they are doing a tox screen. No clue if they are or not.
