Based solely on what we do and do not know (!), i believe robbery can be ruled out. the truck was left behind, the backpack with laptop was left behind, no charges that we are aware of on mom's card or activity in Tom's account (if he had one). I cannot get behind a suicide theory due to the distances involved - basically it doesn't make sense to me to leave your vehicle and walk approx 6-8 miles in the dark, in the cold. And I don't remember seeing or hearing anything about a weapon being found with Tom's remains or anyone reporting a weapon missing. I know it's still possible, but I believe improbable. The idea, also though possible but not probable to me, of a stranger rolling thru town, abducting and murdering an 18 yr old good-sized football player then roaming around the countryside leaving vehicles and items strewn around is pretty far out there. Although we all know we have heard weirder stories and occurrences. A stranger would also have had to leave his vehicle somewhere and get back to it at some point. Per the reports, people were searching all over town most of the night and into the wee hours. I think, and have from the start, that this is someone and more than one to be honest, local. If not in Canadian, then close by. But I think they are from Canadian. I think there are people that know more than they have shared with LE. And based on what we've seen of the LE, they could have shared it with someone that could have gotten the information to the right people to handle it. I sincerely hope I'm wrong, but I think when we do find out what happened, it will be ugly and hard on this small town. Nor am I bashing small towns or LE. I grew up in a town of 500 people and both my parents worked with the sheriff's dept. I think there were things missed or overlooked early in the investigation that could have made a difference.
All of the above is me thinking out loud. Please feel free to correct if I missed anything or remembered incorrectly.
