The dad. The mom was fully aware too and played a key roll in the cover up. Speaking frankly and in watching JonBenet do her routines in the clips they showed...far too sexualized movements for such a young girl. Sick and very creepy. I read people like a book and the parents couldn't have registered MASSIVE GUILT any clearer, I mean it was off the charts. I think it's quite known likely within their precinct, but without proper evidence...nothing you can do, sadly.
The brother or mom
The same people who killed Madeleine McCann, her own parents most likely.
I also think the father did it. Just my opinion.
sick to think someone can sleep at night after killing Jon Benet isn't it.
absolutely and none sicker than those who kill.
