I think the fact that the thread started on tigerdoppings that same date was a coinky-dink.
That guy who started the thread was known already as a member there. It would be just like a member here, who had been posting for awhile, would maybe start a personal thread seeking advice for a family issue.
The thread had NOTHING to do with Mickey's case at all, at first. It was only about this guy and his family being really upset,gy because a young woman with 2 young kids was wanting to marry a sex offender. So this guy posted the picture of Brandon and his RSO listing, and said " What can we do to keep my sister in law from marrying this creep?"
People began giving good advice, like call his PO, call the DA, call LE, etc.
Then at some point, the guy realized that the boyfriend drove a truck like the one that LE was looking for in that case. He stopped posting in that thread and it died out. Nobody was responding or bumping it up.
But behind the scenes, the family of the girlfriend was calling in tips about the truck and the boyfriend. So about a week before the arrest, the guy said everything was about to break and there was going to be an arrest in the Mickey case. People called him out, made fun of him, but turns out he was right. But he also had a 'gag' order after that and so he deleted everything he had posted earlier.
