This picture is a still from a video
taken at 11:34 a.m., 1 minute and 47 seconds before Shawn was standing knee high in water in the cave on Wednesday 3/29/06.

Note that there are three people.  The women on the right and left both have long hair.  The one on the right is wearing a white coat; the woman on the left is wearing a brown coat. 

The key question is what did they see and hear while in the area and as they were leaving?  Did they see and/or speak with Shawn and/or Rob?  Who was holding the camera when this video was taken?
