Justin Hartley's hit series Tracker keeps proving that there's nothing our favorite hero Colter Shaw wouldn't do to solve a case involving a teenage girl - and a triple homicide. In Us Weekly's exclusive clip from the Sunday, April 19, episode of the CBS show, Colter is looking around a dark room for clues when he notices a suspicious man approaching the area. "Someone is out there," he tells a detective before sprinting off into the woods. "I got this, you call for backup." Colter chases the man through the woods until he is finally able to tackle him.
