If a person who signs the death certificate; a district attorney general; any law enforcement officer; or an emergency medical or rescue worker, emergency medical technician, or paramedic who attended the person immediately prior to or after the person’s death, signs a written statement requesting the delay of a resomation based upon a reasonable belief that the cause of death may have been due to other than accidental or natural causes, then the resomation of a dead human body must be delayed based upon that request.
