This is absolutely true. Parsons has a very active Topix forum...more active than most towns, and this case has been discussed almost continuously. Thing is, this is gossip at its highest form with anonymous posters although some of the people call each other out by name.
I think the thing is, the LE knows this and has been watching this, but you can't arrest on heresay. But if some of the actors are arrested for something else, LE can certainly lean on them and offer them an easier plea deal if they roll over on somebody else.
My belief is that it was either someone in relation to the theft at his property which may have been a private individual looking for evidence, or someone else in prison. or facing charges, that is looking to make things easier for themselves by giving certain individuals up.
I agree with Ocean that it is unlikely that they would but this much manpower, equipment and agencies on something unless there was some compelling evidence.
