Just reading about this case. Actually floored that the 22 year old sister living with the family wasn't looked into further. I feel she knew more. I think it was someone connected to her that took Beverly. A friend or an acquaintance who knew Beverly. The sister moved shortly after which I think is odd. Yes, early 20's is a selfish age and she was starting a life but the need to stay close to home in case little sister returned seems a given. I just think the sister knows way more than she revealed before her death.
