@Curiosa20 I appreciate you linking this post- the interview is well worth the watch, presented in a very logical fashion and makes a lot of sense.
It seems that the local Moscow PD realized early on that they needed more resources and reached out for those resources. We see it on this platform with many cases in many of the smaller towns, a local LE department that is perhaps understaffed and likely underfunded. Not unusual in any profession these days.
Mocow PD does not appear to be territorial or leading with ego. I give them credit.
Solving these four killings is a huge undertaking and will take time - lots of manpower hours for interviews and
sifting through the evidence. I agree that profiling will be very important in solving these crimes.
It may be true that the community is not safe until this person is found or the perp may have already moved on.
The killer may be an Israel Keyes type

I think likely the killer was not in the victims inner circle. He was in the periphery/ in the "shadows" - maybe he frequented the local bars where the kids go, could be a local handyman/roofer etc who did work in the area and fixated on one of the victims. I don't think he's going to present as a" scary" guy.
One thing I think we can all agree on is that this is one damaged, deranged and evil individual. We will all rest easier when he is caught.
The sooner the better
Just my thoughts- All IMO
