I can’t recall the exact nature of the sexual assault in the Villisca murders but it is correct, but the post you quoted is incorrect re: the Mueller murders in general - there were sexual elements of some kind involving a female child in almost every murder likely committed by him (and I fully believe Villisca is one of them.)Bbm.
I'm somewhat familiar with this case, but have never heard that before.
It's new to me, anyway.
Imo.
Semi-side note: the book referenced in the quoted post, “The Man from the Train”, is one of the very best true crime books I’ve ever read.
