I'm mostly trying to lurk on this case... mainly because I can't come close to keeping up, and also because there's so little hard information to go on that I'm uncomfortable commenting... but wanted to offer a tiny point of info on this bit.
Sun-sensitive eyeglasses won't get darker in the car, much to my chagrin. They're activated by a type of light that is filtered out by the car windows -- the same reason a person won't generally won't get a sunburn in the car, no matter how long they're sitting in it with the sun on them. It's a bummer for those of us who have to wear glasses and operate motor vehicles during the day. So: the kid in the white car doesn't have darkened glasses on, but it doesn't mean they aren't the transition-type lenses, and that alone isn't a reason to eliminate Kyron as the kid in the white car, though there may be other good reasons. :twocents:
Back to lurking for me. As with everyone else, I'm hoping for Kyron's speedy and safe return to his family.
