I would not react to the supposed FBI vs State Law Enforcement media panic. This comes up in a lot of long running cases. There are good reasons why local forces like help from the FBI which has some specialist resources, but don't want to hand over the whole case - which after all, is in their jurisdiction.
As far as we know, there is a decent chance this was a rando - e,g burglary gone wrong, home invader etc, in which case tracking him down could take some time. Keep in mind it took 6 weeks to identify and arrest Kohberger.
Other types of cases with staging etc can take even longer. Indeed one can find numerous cases where it can take months or years to find the victim. Many times, simply because the perp got lucky despite heavy resource investment at state and federal level.
My opinion, based on a few major cases, where the victim is missing.
That has been my experience too following cases on WS.
We’ve spent hours, days, years discussing possible perpetrators and conceivable motives only to find out that none of the actual perpetrators was who we discussed endlessly.
And that LE had much more evidence and indications of circumstances surrounding the scenes then we ever knew in the least.
It’s at trial we find that LE, who we thought from afar were dullards, knew much more all along.
To an extent they let us WSers stew in our juices not confirming or denying, seasoning with press events that keep things mysterious, salting it unintentionally with non-information “clues” that we seize on for lack of more substantial food.
Then as it’s our impatient human nature, I guess, when the news is slow we start to eat our own then the mods have to remind us to check out other threads to keep us busy.
All imo
