Well they came back and got the truck after the found it, from the mechanic, there is a video about it. And they said for investigation, so if they didnt do prints it just makes me wonder what they could of been looking for is all. Drugs, blood maybe, you would think that would be routine stuff, I just remember them saying they did send some stuff back to the lab and if its not prints what would it be, not that they'd tell us right away anyway due to the investigation, but that part bugs me, if they went through taking it, and did send stuff back, I guess from the outside looking in it just seems odd to me that prints wouldn't be apart of it. I forget what interview it was at the end he said they'd sent some stuff back for analysis, ill try to find it today.
I guess when they said they sent some things back to the lab for investigation it could have been his phone as well. That would make sense.
