The wreckage likely IS hers, but it's by no means definite. If you read the linked article, there's really no more info than there was with the previous piece about "wreckage" being found. I did note that the photos from earlier show a bit of upholstery that seems to match the pre-sale interior photo.
I don't think there's really any mystery here, just somebody biting off more tan they could chew. Happens all the time with motorcycles and sports cars, and sometimes the nimrods live to learn the lesson. Sometimes they don't.
