I don't think it works that way. I think you can only trace relations through mitochondrial DNA which runs through the mother, not the dad?
Oh, it's totally started. Talk about bad wiring in the brain, a bad home life, what happened, must be mentally ill, etc.
You know, I buy that if the kid is 14 or younger or if it was a spontaneous thing or even a more remote killing like a shooting from a car, or a fight leading to death, etc.
But this kid dismembered Jessica's little body!!! Do you guys realize the coldness it takes to do something like that? How difficult it is? How bloody? How long it takes? And he apparently tried to abduct a grown woman earlier! This is no poor baby who suddenly lost it!
And I have to really admit to serious frustration when comparing how this creep is viewed compared to the ones who killed Autumn. Really, I have seen ZERO discussion about possible schizophrenia or mental illness when it comes to those boys. No, it's all about how evil they are.
Oh, and yes, there are some who give credit to those perps' mom for turning them in, but I see much more love given to this one and zero suggestion that she only did it for reward money.
I am not happy about the discrepancy in the cases. Especially as this killer seems much more sinister with the dismemberment.
Psychopaths do confess - Jon Roberts, Ted Bundy, Joran Van Der Sloot (about Stephanie Flores), Arthur Gary Bishop, Westley Allan Dodd, etc., etc..
Also, I think it's not 100% correct to say that all psychopaths have zero remorse of any kind. I think it's a spectrum. That's why some serial killers will confess to certain murders but not others - the others being those they felt somehow a bit more bad about - and why they sometimes cover their victim's eyes or faces, so the victim can't "look at them."
It takes a tiny bit of feeling to not want a victim to see you or to not want to admit to certain murders even while admitting to many others.
