How can you be so sure of this? He was taken out of his class the next day and interviewed. Are you sure he didn't disclose info about the two cars? We've never fully heard what the extent of the 911 call or the discussion at the woodpile with LE disclosed.
Ok, so let's go with Dan's own words that he has repeated in each interview. He told 911 operator there were people with flashlights by his woodpile and thought they may be stealing. He was then told about the abduction at the end of the driveway. He hung up and went out to speak to cops who told him the same thing. He told cops he would go search his own outbuildings.
He did not once mention the small dark car with it's small passenger that came through the driveway at almost EXACTLY the time of the abduction OR the tan Monte Carlo that tore through in the afternoon that he has said 'find that car and you have your kidnapper.' He didn't mention any cars coming through, why? Why did he not give cops key evidence, FindTim? These are the words he uses in EVERY interview and never mentioned these other cars in the driveway.
