GAMEPLAY/XP FLOW
Coroners will be able to make some preliminary examinations of the decedent in the field but for determining the actual cause of death the decedent will need to be removed from the scene and taken back to the ME's office for a full autopsy including toxicology panels.
Autopsies will be a lot more in depth than what can be determined in the field and will allow for identification of calibers or melee weapons used.
Small chance that someone beaten to death will have traces of DNA from the attacker on their body and if detected it can be processed
Coroners will get XP through two main ways, removal of a body or completing autopsy reports/tests.
Coroners will be able to identify decedents during autopsies but depending on how long they have been dead it might be unsuccessful or take longer

VEHICLES & TOOLS
F350 Utility (For special operations)
Hazmat gear
(RANK Limited) DPMU - Disaster Portable Morgue Unit
Will be able to be deployed from the F350 utility and will be able to do most if not all capabilities of the morgue in the ME's office except for removal of the body
