Justin Hartley's Tracker promoted a cast member after numerous exits ahead of season 3. It was confirmed that Chris Lee, who plays Randy, is now a series regular, according to Deadline. He first joined the show in season 2 as Bobby's (Eric Graise) cousin before returning in a larger capacity. 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 (Hartley) travel the country to help solve various missing persons cases.
