I always go back and forth as far as LE involvement and communication. I remember the
Adam Gilbertson case, and how there was pretty much no PD help, communication or presence. So many people here were convinced that LE was so quiet because they knew something, that they were just getting their ducks in a row and it was only a matter of time before they told us what was happening. Well, that wasn't the case. The family had to search, and it was actually someone in their own search party that finally found poor Adam (RIP) a month later, dead in the river.
Adam Gilbertson’s death ruled accidental, had opiates and cocaine in system
So, when LE is quiet, don't always assume it's because they know so much and are about to crack the case. Sadly, it's often the opposite. They have nothing, or are just not interested in helping for whatever reason.
