Hey guys I've read most all posts on all threads and want to chime in on the white truck pictures. I live in Baton Rouge and Mickey's disappearance is a HOT topic, I pray for her safe return.
My husband works with cars/trucks for over 20 years.I would call him an expert that can tell you make/model/year of most GM/Chevrolet vehicles since 1950's. He agrees with Chicken Fried's assessment of the car, it's not a Cadillac, most likely an Oldsmobile.
I've seen several posts about the white trucks and want to share some observations from the pictures.
The truck in this picture
http://findmickeynow.com/pic1.jpg AND the truck in this picture
http://findmickeynow.com/mickey2.jpeg near Circle K are quite possibly the same truck.
Both pictures show a 2004-2006 Crew Cab GMC/Chevrolet with aftermarket 20"-22" rim with a white hard bed cover. dark tinted windows all the way around, chrome door handles and possible chrome gas door. Those are the only years that body style was offered as a crew cab with a short bed. These trucks are half-tons b/c they did not have a full 6ft. bed. The picture is too blury in the Cirlcle K pic to see a bed cover.
The truck in this picture
http://findmickeynow.com/mickey2.jpeg is a 2007-2009 Chevrolet Crew Cab with factory rims, possibly a Z-71. If it has a bed cover it is NOT white.
ABSOLUTELY NOT THE SAME TRUCK AS THE OTHER 2 PICTURES!
Based on this information, any speculation that the same white truck was pictured twice at the Circle K going in different directions would be incorrect.
