IMO I feel this picture or video of the guy was coming fast towards Libby?and she took this video in a few seconds? before it was knocked out of her hand or she threw it with or without him knowing.I feel IMO her cell phone was on the ground,near the bridge.Down the hill.Nottoo far from this encounter.
There are two pictures of him. It appears they are in succession and the way his legs move appear like hes walking, not running.
