Idaho Code § 67-7036
The director of the Idaho state police, jointly with the various county coroners, shall provide a system and procedure whereby all coroners in the state of Idaho shall obtain blood samples from all vessel operators who have died as a result of and contemporaneously with an accident involving a vessel.
All investigating sheriffs, deputy sheriffs, or police officers shall report such fatalities to the county coroner or follow the procedure established by the joint action of the director of the Idaho state police and the various coroners.
The blood sample, or result of blood testing, with such information as may be required, will be delivered to the director of the Idaho state police or his designee. Upon receipt of such sample the director will cause such tests as may be required to determine the amount of alcohol, narcotics and dangerous drugs contained in such sample.
The results of such tests shall be used exclusively for statistical purposes and the sample shall never be identified with the name of the deceased. Any person releasing or making public such information other than as herein prescribed, shall be guilty of a misdemeanor.
