Justin Hartley's hit show Tracker has lost several main characters after just two seasons - but who is still left from the cast? CBS found success with Tracker immediately after it premiered in February 2024 to record-breaking ratings. Viewers have since tuned in week after week to see fictional survivalist Colter Shaw (Hartley) travel the country to help solve various missing persons cases. As Colter has gotten help, the ensemble cast has grown with characters such as handlers Teddi (Robin Weigert) and Velma (Abby McEnany), hacker Bobby (Eric Graise) and attorney Reenie (Fiona Rene).
