I totally understand the frustration at what happened, but Fremont County coroner is a very low paying part-time job with 24/7/365 responsibilities. The ultimate responsibility of the coroner is to make sure the Sheriff knows and investigates if something is suspicious.
The part-time, elected, no medical training required coroner system should be changed IMO. But that is a far different statement than saying this particular coroner did something wrong in this particular case.
All MOO.
Idaho Code Ann. § 19-4301.
"If a death occurs that is not attended by a physician and the cause of death cannot be certified by a physician, the coroner must refer the investigation of the death to the sheriff of the county"
