S01E12 Vigilante

As a series of murders targets both the infected and those who appear innocent, it becomes clear that a killer is hunting down individuals impacted by the alien signal, using their amplified brain waves to track them. The connection between the murderer and Bighorn crew member Manning raises questions about the motive. With this method of detection, could Molly, Cavennaugh, or Lucas be the next potential victims?
