Me too! And ... rintense, I think your idea of the van being a ruse is a good one.

Earlier, someone said there were always motels (not that uncommon) by the offramps where the shootings took place. Driving there would have been relatively easy, while the cops are busy running up and down the freeway. How about the shooter sitting in the motel watching the whole circus on TV - to get his jollies.

Motels and truck stops--and some combined. The shooter could blend into a truck stop easily as well.

I'm pretty sure that LEO's are canvassing the motels, or will be soon. I'd guess that most motel clerks are going to be pretty vigilant of getting license plate numbers at check-in. And any rental car agency is foolish not to have cameras in their business, so you've got a likely trail if the sniper tries to lay low in a motel.

And it is just going to get riskier for the perp, as more people become vigilant.
