I'm betting he borrowed that car to dispose of the body.
Not only that, but it was 1 1/2 hours after he was dropped off back home. Plenty of time to do the deed and clean up as best as possible.
Notice that the mother gave him the keys then went into the house. Where was the body? Was she still there when he came back at 7? Supposedly, then she took her car home. She noticed nothing wrong during that time? Strange.
What if the girl wasn’t already killed by then? Where was she? How did he get her in the car? (This, of course, presumes the step-father’s guilt.) There are a lot of unanswered questions.
Copeland said several items have been taken from the home where the girl was last seen and authorities have seized David Spear's truck.
So Spears had a truck.
So what, exactly, did he need his mom's car for?
