The information I have is this: she died Possibly in Colorado, cremation is taking place there and then remains are being sent to the family in Wisconsin. A memorial is being arranged for the spring. This info isn’t from Cody or Diana, another member of the family.
I haven’t searched for the information in the media or anywhere else, and the info from the family member was given to me by someone else who got it first hand.
Cremation is around $4,000 unless she planned ahead.
If she did not go by car accident, someone needs to get the car (of it's worth getting) but there's storage fees that accrue from day one. I believe, if they surrender the car, there is still a bill needing to be paid.
Unless she died of pre-existing and currently-treated conditions, I'd imagine an autopsy would have been in line.
San Diego's corner has a report, I know, had enough friends listed...
