I don't know.
My 86 year old mother died in a car accident in FLA. I was told not to make funeral arrangements until an autopsy was done.
I was upset and questioned it so I contacted a local politician's office and asked why was an autopsy being done? I was told that it was a state law in FLA. and something the highway patrol had lobbied for.
The autopsy was done quickly and we buried her 4 days later. I also got a copy of autopsy report. Results...trauma from a car accident.
