Stands out to expert? one person or more than one person? What stands out is malice of forethought and to position himself to be so elusive. Route 64, Route 295, other major arteries. Problem just got a little bigger.
Bad guys scout out area in advance? Alot in advance? ABSOLUTELY. This guy has not had a car accident, jumped a curb, etc, merely disappeared. Knows how to get out of the area. Path of least resistance to leave the area. No doubt that he surveilled the area first. They have their cameras on scene.
Perhaps the last 5 days of no activity has been used to scout out new target sites outside of the current perimeter.
