Falco was a mercenary working for Santana. He was one of the eight mercenaries who intercepted a distress beacon to find and kill Riddick. During a night patrol, Falco, along with Vargas, were looking for their fellow partner Nunez. To no luck they were unable to find them. When Vargas quickly froze, getting no response from Falco, he turned around to see Riddick dragging him into the darkness.
Later when Boss Johns, along with Moss and Lockspur, found his body after presuming it is Riddick. Boss Johns later saw it was a diversion, allowing Santana to unintentionally open the locker and then stealing both ship power nodes.
