Good questions. I think most, if not all, of LE statements at the PC make sense if LE does not know the identity of the suspect. On a side note, I went back and listened to the Best Case Worst Case podcast about this case. The first time I heard it, the co-hosts agreed that an arrest was imminent. But I listened to it again and that part now seems to be edited out. I remember, though, that one of the co-hosts said she believed LE was closing in on the killer. But, she added, if nothing happens in the next three weeks, it [the PC] might've been a Hail Mary. That was three weeks ago.
