It's hard to imagine it takes 4 days to talk about her JC bag, but, a handcuff box and used condoms get same day coverage in the media, isn't it?
Could be as simple as a reporter happened to be on the scene when LE was notified about the finds.
From what I can see from over 2000 miles away, it looks like the media is all over this case. They're bound to get a few lucky scoops just because they are right there all the time.
And if this isn't the first time this area was searched, why did they go back a second time? (actually I thought they said there weren't any searches scheduled yesterday, so was confused about how a kk team member found them, but I digress)
How can they move forward to new areas if they keep going back?
Maybe that's the point. To keep the areas searched honed right in this neighborhood.
From my experience in watching other cases, it is very, very common in missing persons cases for LE to do a quick search of the general area (hoping to find the victim alive). If the victim isn't found quickly, then LE goes back and conducts a much more involved, detailed search, looking for every tiny bit of anything that may be evidence.
And sometimes they go back over the same areas a third and even fourth time.
This happens so often that I believe it falls under Standard Operating Procedure.
It's logical; in the first days, the highest priority is to look for a victim who is perhaps injured or ill. They're looking for great big objects, like whole victim or things that are obviously the victim's belongings. Time is of the essence. For instance, what if Sierra had been hit by a car on her way to the bus stop, hit her head and wandered off in a daze before collapsing.
Once it is clear that there is no living but injured victim in the vicinity, then it's time to go back and search again. This time, looking for any tiny thing that may be out of place (like used condoms).
As time goes on, some things that may have been out of sight get pushed into sight by the growth of vegetation, etc. So it's time to go back yet again and see if there is anything that was missed the first two times.
