This guy's family-owned trucking business since the 1950s doesn't sound like the perpetrator. His story about the truck being sold sounds plausible to me.

Confirmed by local news in Iowa that the reefer trailer was sold because the reefer unit failed. It was sold as a box trailer.
Absolutely... And it sat there and ran out of fuel with these people inside.
