Videotapes from days before the crime have been recovered and one is of particular interest. A trio is shown entering the museum very soon after it opened; a tall, middle-ages man, a portly woman with a diamond ring, an an older man matching the description Janie Clark gave are shown. Because of their distance from the cameras and the strange camera angles, you are unable to make out much facial detail. In fact, most of the time the trio was at the museum, their backs were to the cameras. It looks as though they knew about the cameras and actually turned so that they'd be facing away.
The black & white video also makes it hard to determine details such as hair color. Something Janie never mentioned: a backpack is apparent. The old man has a backpack slung over his shoulder. The color of the bag cannot be determined but the type and shape of the bag appears to be rather common.
Now that you’ve seen this footage, any thoughts?
