My Opinion. We do not know who LE has investigated. I never mentioned kidnappers, real or otherwise. If LE could prove TMH was indeed the last person to see Kyron she would have been charged and arrested. I don't think anyone is keeping a secret.
I agree. One huge obstacle for LE is the huge amount of time that elapsed before Kyron was reported missing. His backpack and coat were in his classroom and other students pointed it out to the teacher yet she didn't have the school contact his parents. That is a fact that Terri could not have anticipated if she indeed is responsible for his disappearance.
