My new idea. What if LE knows who it was, but the way they got information was accidental and not anything that can be even mentioned in court, much less stand there. There are many ways of data mining, after all, some are legal, some not, and some are simply hush-hush. I wonder if after they got this information, they, indeed, sent the suspect’s DNA to compare with whatever scanty amount they got from the CS, and it matched…but like a 111-marker Y would match a 12-marker one. (A non-match does rule the person out, but a match can indicate a whole group). I also think it happened somewhere in the end of 2018, so between the time they got their info and the time of the PC in April of 2019, they, indeed, hoped to get something tangible by putting a pressure on someone (a partner?), but it didn’t pan out. So in April, LE came out with all their “homework”, such as “the right sketch”, etc., but nothing to show and no name to spell out. Furthermore, I suspect the person is an upstanding citizen, so there is no way they can imprison him for something unrelated. Maybe they hoped he’d pop up in the CSAM group, but he did not. So there is a stalemate, and hence RI said “if he does something else again”. He probably has somehow suffered, didn’t get a promotion, life put on hold, but he had not been brought to justice. And they know what tip they are waiting for, but no one has called. JMO.
