I agree. Local LE gave the PC a couple weeks ago. But remember, the FBI was called in early in the investigation. Do you think they stepped in for a few days and then stepped back out before the case was solved? All the PR's that have come out from the family have only referred "the investigators". The FBI has psychologists, profilers, etc. Kyron's name is found 12 times in the e-mail. The e-mail talks alot about Kyron's little quirks, things only his parents would know about him. TH was his parent too, for most of his life. IMO, local LE figured all this out very early on, maybe just before the point at which the FBI was called in. They know what happened but they have to be able to prove it. Getting her to confess is the best and maybe only way.
