Drove through Waterloo this summer and have to agree that both locations would only be on the radar of a local. Maybe the perp is similar to the new POI in the Jacob Wetterling case: a loner, low functioning, probable history of sex crimes but no actual criminal record. DNA technology finally advanced enough to ID him in a similar abduction. Hope that will be the case for the girls.
Off topic but WOW! I had not heard about the new POI in the Wetterling case. I never thought DR did it and have long hoped that the actual perp would be caught so DR's name would be cleared. Poor guy, there is nothing that could possibly compensate him for the hell he's gone through over that case.
Having done some reading on this new POI, I think they've got the perp. And, just as has been theorised with this case, turns out he had been interviewed about Jacob Wetterling back in 1989, so he was already in their files. They just didn't pick up on him and DNA testing was in its infancy back then. This new guy has been DNA connected to the Cold Spring assault case prior to Jacob Wetterling's abduction. That abduction was one of a number of very similar assaults, which included one in which the perp confronted two boys, singled out one and sent the other running for his life (from the boy's point of view).
As a dog trainer, something I often say is "it is never the first time." Meaning that when someone brings me a dog that suddenly has a behavioural issue, the triggering event is never really the first time. Even if the owner swears up and down that the dog never nipped or bit before, when I question them it always turns out that the dog had a long history of showing lots of signs of fear and discomfort (well over 90% of all dog bites are fear motivated) but the owner never really put the dots together. This new POI may not have abducted and killed any of his previous victims but there's definitely a pattern there. Jacob Wetterling would not have been his first time.
I also find it interesting that this new POI is not a POI for any other (probable) murders. That ties in with what RichKelly wrote about the perp in Lyric and Elizabeth's case: the perp probably doesn't feel good about killing them and he may well never kill again. My guess would be that if the POI for Jacob Wetterling never killed again, that he himself felt ashamed and guilty over killing Jacob. It may have been done out of panic rather than a specific desire to kill. He clearly got something out of assaulting tween-aged boys but maybe that's it. He didn't want to kill and once he killed, the memory put him off further attacks. Or, at the very least, further murders.
