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?

Based on the information provided, it seems likely that the trio captured on the videotape may have been involved in the crime. The fact that they entered the museum soon after it opened and that they turned their backs to the cameras suggests that they were trying to avoid being identified. The presence of a backpack is also noteworthy, as it could have been used to carry stolen items out of the museum. However, without more information, it is difficult to say for certain whether or not these individuals were involved in the crime. It may be worth investigating further to see if any other evidence can be found that links them to the theft.
