I haven't followed this case too closely but something that happened about a half hour ago made me want to lurk a little closer. I was driving south on 15 near the 8 interchange (about 30 miles directly south of Escondido) and a big Suburban type SUV passed me and in the windows I saw a group of very sullen, sad kids. I thought, 'why do they look so sad, it's Friday, it's sunny outside?' Then I noticed that plastered over the back were big signs about missing Amber. Behind the suv they were towing a trailer, like maybe used for hauling stuff. The trailer also had a sign on it. I suddenly got very sad, like maybe they were schoolmates or friends of hers.
The FBI could have been brought in for a number of reasons, internet usage, crossing state borders, crossing NATIONAL border (which is certainly possible here.) Whatever, it all doesn't look good at this point.
