I just had an insight that most of you have probably already had. I was just thinking about Jon Benet, and Polly Klaas.
Like Jon Benet, Jayme participated in competitions where little girls were dolled up; in Jayme's case it was dance costumes. (Please, let's not get in a debate about whether pageants and dance contests are good or bad for young girls. I'm just drawing the comparison).
In the Polly Klaas case, the Perp picked her randomly. He asked the children present in her home - whose home it was. It was Polly's, so he took her.
The point to this is that Jayme could have been stalked by someone who became fascinated and obsessed with her at these dance exhibitions. Or, it could have been something as random as the Klaas case.
As far as the dance recitals go - we know that those with unhealthy fixations on children tend to work in capacities where they can have easy access to them.
Hopefully LE has explored this avenue.
