I ran into 2 last night, but they are not well known cases (I cannot even remember their names but they were both girls around 12 years old). I think news coverage has a lot to do with it, too.I haven't come across any children who were murdered in the past 7 years or so by a non-family member who body was found, with the murderer still at large...has anyone else? I am sure there are some, but not finding them. Seems like they are usually caught.
But as an aside, BTK killed for 30 years before he tripped up (and I personally think he got himself caught on purpose.)
If this guys DNA is not on file, if he is truly a sociopath with no remorse that will not be behaving differently(cause it was just another day), if he just picked Jessica at random because he could, and/or if he was just passing through, it will be very hard to find him without really great evidence.
