10:30 a.m. : The Savopoulos family Porsche is last seen at the home, it is found later in the day in Prince George's County.
I think that Daily Mail did sloppy reporting. Upon investigating other links, it does seem that the Porsche was last NOTICED at 10:30 and that would have been JW's sighting, IMO. I don't think it was leaving at that time. Just "noticed".
But you're not crazy. You DID read that!
