The ONLY thing that makes me think that the girls did NOT know their perp was the fact that the purse was left behind. The bikes being at the lake would be enough for someone to think they would have possibly drowned.
That said, I guess adding the "left behind" purse also feeds a possible staged scene that they were abducted, because (like me) people would assume she would take her purse with her if it wasn't a quick abduction.
I don't think this crime would take too long at all if it was planned out from start to finish from the get go. Literally less than 2 hours. If someone had an afternoon off could easily have done this...job or not. However, would it throw up a red flag for someone to take a Friday afternoon off in the middle of summer? Probably not.
There are two things I just struggle with trying to understand with the whole abduction itself and any possible perps:
1. I just can't wrap my head around the fact that if the girls DID INDEED scream, kick, fight, and scratch, like they'd been taught how did NO ONE hear or see anything? This in turn, leads people to assume this person was known to them, and they went willingly.
2. Someone, somewhere had to have seen SOMETHING. Something has to be askew somewhere and this person who has an idea isn't talking, for whatever reason. Is it a family man whose wife KNOWS he took the afternoon off? Someone who is completely off the radar? Is it someone who is well known in this family who everyone thinks "oh my God, how DARE you even SUGGEST this person could do this?!!" Is it someone who this is their first offense and just got lucky?
I mean really, if this is someone's first offense...never been charged or convicted of any other crime, and abducted these two girls on a whim and has ZERO connection to these girls; the chances of actually finding out who did this is next to impossible...especially if the perp is "such a great family guy". 9 times out of 10 even if the wife DID know, she isn't going to talk...for fear of her own life (assuming it IS a man).
I am not sold on the drug connection. I personally feel if they were killed to send a message they would have done it right on their front lawn. No reason to take and hide them in a park 30 mins away. This perp did NOT want them found right away, for whatever reason. I am of the belief that 7 bridges was nothing but a dumping ground. I think this person took them somewhere else and killed them, and then took them there under the cover of night and dumped them. I don't think they went straight from Evansdale to the park. JMO of course.
