If that info is accurate, there is a memorial service and it is in Denver, is any if the local media covering it? If nobody’s talking, seems to me like that would be a good time and place to get some answers.
And it’s a memorial service? Was there a funeral? If so, with or without a body? If no body, why not? If the family has/had the body, was an autopsy conducted? If so, when and by whom, with what results? If no autopsy, why?
