I feel very sorry for them, and for any other family that loses a child, especially in such circumstances. I believe they are innocent. I just feel sorry for their younger children, they're going to grow up with very few memories (if any) of their sister but will forever have to deal with their parents' pain at their loss, uncertainty and guilt (for leaving her) - perhaps they'll even grow up suspecting their parents are murderers, who knows? But they're going to grow up with that cloud hanging over them as a family unless it's resolved one day or another.
