In the Disappeared episode about Molly Bish's case, they show pictures at the beginning. I think one of the pictures is a still picture of the crime scene (the lawn chair and Molly Bish's belongings on the beach).
One question I always wondered about this case was if Molly Bish actually sat in the beach chair? One way to have been able to tell would have been to have someone who weighs the same as Molly Bish sit down in the lawn chair.
The reason I wondered about this is because I saw something in the picture that I thought might be important. It is a small detail.
It looks like Molly Bish wore loose fitting sandals. I am going to assume that Molly Bish is like most of us if we were wearing loose fitting sandals. In order to take them off so you do not have to bend over you put one foot in front of the other and slide the sandal off your foot. This would mean once the sandal comes off it would be at least the length of your other foot in front of you. But the sandal in front of Molly Bish's lawn chair looks too close to the chair for this to have happened. Since the sand does not look disturbed around the sandal this is why I wondered if she actually ever sat down in the lawn chair.
I know there could be many different explanations like maybe one of the mothers or children at swim lessons that day moved the sandal closer to the lawn chair. Some reports say at one time both sandals were positioned in front of her lawn chair, so it is hard to know what information to believe.
There does not seem to be any sort of evidence that has been released to the public. I think police should release more information in her case if they have it. As for who abducted and murdered Molly Bish, it remains a mystery.
