Let's assume it was their truck. Couldn't it have been that Kaine and/or Terri did drive around the neighborhood at some point(s) to see if Kyron had tried to walk home, was hurt, etc? The first time was "around 3 pm", which would have been around the time they learned that Kyron was not on the bus and had been marked absent at school. 2 am, I will admit is an odd time and the police were involved in the search by then. But, they could have went out driving again out of desperation. I know my parents did that with me if I was still out riding my bike too late or something.
I was thinking the same thing at first. I could totally see myself driving around aimlessly as well...
The only thing that made me discount that idea was that I would have come forward immediately in order to explain that it was me - if nothing else but to make sure that LE wasn't on some wild goose chase...:waitasec:
