It it has not been made public but there is speculation she drove her van.
It's this image that interests me. Of course the damage could be completely unrelated but it appears to be very recent. Could just be backed into a wall or bumper (think you call it a fender in the US) damage. Following a trail of financial gain is certainly much more interesting, and I admit my thoughts on this are much more mundane than that, but I'd still be looking at this as part of the investigation.
