I think count seven is worded very interestingly:
"[The Ramseys] unlawfully, knowingly and feloniously render assistance to a person, with intent to hinder, delay and prevent the discovery, detention, apprehension, prosecution, conviction and punishment of such person for the commission of a crime, knowing the person being assisted has committed and was suspected of the crime of murder in the first degree and child abuse resulting in death.”
It's easy to read that and think the Ramseys, themselves, had abused JonBenet. However, it reads that they assisted someone that they knew had committed child abuse resulting in death. I can't think of another person in the world that the Ramseys would "render assistance to" other than one of their children.
Also, count four reads:
“[The Ramseys] did unlawfully, knowingly, recklessly and feloniously permit a child to be unreasonably placed in a situation which posed a threat of injury to the child’s life or health, which resulted in the death of JonBenét Ramsey, a child under the age of sixteen.”
I think the keyword there is knowingly. This would mean that the Ramseys had been aware that JonBenet was "placed in a situation which posed a threat of injury" and that a reasonable person should have understand that. So, what is it that led the Grand Jury to believe that they should have known she was in the position to be injured or, in her case, ultimately killed?
There is something in the evidence that the jurors saw that made them believe the Ramseys had enough information prior to JonBenet's death to have a reasonable conclusion that she was unsafe and should be removed from that situation. I have seen this charge before, typically, in child abuse cases that involve a parent not protecting a child from their partner's abuse. However, neither parent is charged with outright abuse.
So, who abused JonBenet? What made the Grand Jury believe that John and Patsy should have known that she could be injured or even killed? I'm not sure that I've seen enough evidence about any suspect that would lead me to that conclusion. So, what could be so dramatic as to lead to that count?
