That was exactly what Sheriff Fitzgerald in the Jayme Closs case said at PC's and interviews "we are waiting on that one tip". As it turns out, they had absolutely no idea who they were looking for, granted they didn't have audio or video of the suspect either.
Exactly... they didn't have any idea who they were looking for but they never let the public, therefore, the killer know that. Bluffing is another useful LE tool for obvious reasons. I think bluffing is what the LE in this case has been forced to resort to, as well.
Rather than "release more information sooner" maybe LE didn't have and still don't have usable information to release. True, the LE in this case has video, a photo from the video and audio recordings. Looks like those "extra bonuses" have turned out to be useless even when released.
The sketches: Maybe the first created sketch was not released because the face looked nothing like the photo/video of BG as seen on the bridge. (Maybe LE was in agreement with some of us who have felt that way since the latest sketch was released.) So many of us still bring up how difficult it is to "see" the young man's image in BG's face. Some of us still insist the "older guy looks like BG and the new sketch doesn't." It's an overall impression created by the older-guy "pixel face." Maybe the narrative given by the witness who helped create that sketch did not seem reliable for some reasons. "The guy I saw looked like this." So? A lot of people were there that day. Maybe other sketches were produced from that day, too. None of them looked like the guy on the bridge except for the image that was first released.
The audio sound: It's possible the only usable part of that tape has already been released. A stranger ordering me (calmly or not)... telling me, at the age of 13 or 14, to go down a hill into the deeper part of the woods would have caused me to cry and then plead... and cry again about my mother and father and my sister and... everything... because, deep down, I know I'm probably being taken somewhere so I can be killed and I'm about to die in a horrible way at any moment. I have no time and the terror of it is overwhelming...
Yes, I know Libby was brave... but she was 14 and no doubt was nervous and maybe a little bit afraid but I doubt she though he was going to kill them at the time she left her phone on. I think when she left her phone on she might have only thought she was going to catch the guy saying something or touching one of them... being a pervy-AH iow... but taking them into the woods to kill them? No... the girls would have taken off running, imo.
Abby and Libby were just kids... they didn't march bravely, like soldiers, to their deaths without a sound, imo. Since they were closer to the recording device and BG was probably
behind them, whatever he might have said could be nothing more than background sound and is probably unusable for recognition... and inseparable from the girl's voices. Who would release
that for public consumption? BG might have enjoyed the crying and pleading so much; was so excited by it, he might have let them go on at it without saying anything at all. As long as they didn't scream; fine by him. Who wants to hear something like that?
People either don't or are pretending they don't recognize his voice upon hearing what we've heard already, imo. It may sound like a typical "Midwestern-y voice to us" but would not to his mother or father, siblings, friends...
They either have chosen to say nothing or they haven't heard the recording imo.
DNA: We still don't know if they have usable DNA from the killer.
What if
nobody saw BG that day? What if he came in through the south end of the park. Took the girls from the south end of the bridge without even one person having seen him and left by way of behind the cemetery. Maybe he was dropped off at the cemetery and was later picked up at the cemetery. Possibly, it is the person or people in the car who
could have dropped BG off that LE are appealing to for information. If those people exist, did they know of BG's plan or not...
BG may have seen the girls dropped off by KG at the back entrance but I doubt he entered the park by way of either entrance. He didn't need to enter the park by the formal or back entrance so why would he? I don't think he would. It would be better for him not to.
Evidence: We don't know if even one piece of
usable, physical evidence was left behind.
