For those of you just coming on board today, I want to recep some of the story, since I read the whole thread last night and its still reasonably fresh in my mind.
Timmy's Mom took him out of school early on a Wed afternoon. She took him to the mechanic, where her car was serviced. They spent time at the zoo while this was happening. Then, she drove them to a water park and checked into a hotel Wed night. Stopped to purchase clothing and toys for Timmy (items never recovered). Checked out Thursday and went to a second park and checked in there. Checked out Friday morning, drove around, spoke to family - including a welfare check on the phone for Timmy - then is seen after several hours purchasing supplies without Timmy. Checked into a third hotel without Timmy, and committed suicide. Left note claiming that Timmy was with people who care about him and that he would never be found.
There was blood found in the car, which was explained as remnants of a nosebleed - but that was undetermined.
Mom's cell phone and Timmy's backpack and the items purchased while ont he trip were not discovered with the Mom when she died. She had changed her clothing from the videos of her when she was with Timmy, that original clothing also was not recovered. Two years later a woman turned in the cellphone. It had been found on the side of the highway near where the last phone calls had been made and was not turned on until right before she turned it in.
All computer, social media and phone searches have given no clues. It was discovered that the Mom had traveled to these same areas at least twice in the winter preceding the trip with Timmy. No one from the family was aware of these trips, nor had a reason for them.
Back when this first happened, people on Websleuths were split between thinking Timmothy was dead, or that he was alive and being held in secret somewhere. Since there is a lot of Amish in the area, that was a popular theory - someone also found a message on a public bulletin board in the month prior asking if Amish would take children from English people (thats what they call us). No one was thinking abduction. It seemed like the lead investigator was of the mindset that Timmothy was still alive, but they normally seem that way unless there is strong evidence of foul play.
