I haven't read through the rest of the posts so forgive if this has been addressed.Hmmm...well, they located DS the evening of the abduction and then they located the truck two days later IIRC. I have still seen conflicting reports of where it was actually parked-both two streets away and in a space at the apartment complex.
I feel pretty certain they impounded the vehicle when they found it-they probably didnt have to get DS' permission to look at it if he was/is not on the title. They might have had to get a warrant to seize the other car however.
DS didnt cooperate at all, right? So it seems unlikely he gave permission for any of the searching that was done....
Now, what might be the delay in having the truck arrive in MI? I cannot think of any, unless they are just misleading the public and the POI.
My only thought on the truck delay is that this is a potential crime that has crossed state lines now involving the Feds. and 2 states. The red tape under those circumstances has now tripled IMO
