Which tracker stars are returning – and not returning – for season 4 after releases?

That of Justin Hartley Tracker faced many surprise exits from the cast – so who is and does not return for season 4?

The hit CBS series, premiering in February 2024, features fictional survivor Colter (Hartley) as he travels the country to help solve various missing persons cases. The ensemble cast grew with characters such as Handlers Teddi (Robin Weigert) and Velma (Abby McEnany), the computer hacker Bobby (Eric Graisé) and lawyer Reenie (Fiona Rene).

Weigert’s character was struck off and McEnany and Graise soon followed.

“I think it’s evolving. If I can’t evolve these characters – Randy or Reenie or Bobby – they’re not just people picking up the phone and saying, ‘OK, here’s the answer.’ That’s when the show calls it quits,” executive producer Elwood Reid told exclusively Us every week in May 2025. “The challenge is when you have to learn more about them, which I found interesting. That’s the challenge of the show, is to not let it fall into a formula.”

Reid emphasized that they did not want Tracker has “fall into complacency.”

“The only rule I really have on the show is that every week, Colter will come to a new place and there will be a new case. How he gets those answers and what he uses on the team, that’s all something that’s up for grabs,” Reid teased. “Meeting these [local] queer characters are something we’re going to try to do more of as the season goes on. Just Colter coming in and interacting with other characters. It’s fun to see Justin flex his muscles with some really good guest actors.

Most recently, Reid weighed in on the on-screen changes. “What we realize is that there are characters that pop up and if it worked we would bring them back,” he said. We in December 2025. “I think the show can’t always do that. But when it does, the world feels a little more connected.”

Reid noted that there was only one constant in the series: Hartley’s fan-favorite character.

“The audience is interested in him because they’ve seen this character before. But I think they still think that the core DNA of the show is Colter. With this guy, what makes him appealing is that he’s a mystery to himself,” he added. “He is a mystery to the audience. We see him and his spare moments putting together some pieces of his past.”

He concluded, “I don’t know if we’ll ever get it all together, but it’s going to be hard to keep doing it. That’s all we thought. The biggest improvement we made this year – in my opinion – was bringing people together in the same room. Just that connectivity, I think the audience likes to physically see their characters in the same place.”

Now that CBS has renewed Tracker For season 4, keep scrolling to see which actors are returning – and not returning:

Justin Hartley

There would be no Tracker without Colter Shaw, so Justin Hartley is should be in the foreground in season 4. Hartley, however, did not rule out Colter’s death in the future.

“It’s important to keep raising the stakes. I like being Colter as a hero, finding people and all that. I also really like seeing him in a suspenseful thriller and in a dangerous situation,” Hartley told The Hollywood Reporter in April 2025. “I don’t want our audience to forget that this man is mortal, he’s not a superhero. He can die! The things he does are very, very dangerous.”

Robin Weigert

After joining Tracker in season 1, Robin Weigert’s character was written off in the premiere. She is not expected to reprise her role in future seasons.

Abby McEnany

Season 2 caused more concern when Eric Graise was noticeably absent for six episodes. News later broke that Graise and Abby McEnany would not be returning – at least for now.

Eric Graisé

Eric Graise’s Bobby was absent for several episodes before being officially written off. There has been no word on a return and Graise and Abby McEnany have yet to break their silence on their respective departures.

Fiona Rene

Besides Justin Hartley, Fiona Rene is the only remaining OG cast member from the show.

“There’s going to be an attempt to build the rest of the characters — particularly what’s going on with Reenie and where we left her and what her life is like,” Reid teased Us in August 2025. “The show always comes back to that. What makes the show work in my opinion is that Colter is a guy who comes in and says, ‘I can help you.’ It works every time.

Chris Lee

Chris Lee was recruited before Eric Graise left – and should come back.

“Having Chris Lee in the same space as Fiona Rene allows you to get [more]. The things we’ve seen so far are so fun. It’s made a huge difference,” Reid told TVLine in September 2025. “Now when Colter calls, it feels like he’s calling something that’s already in motion. This is all part of my “evil plan” to use Fiona more: the more you can build her world, the more the series will benefit.

Cassady McClincy Zhang

Cassady McClincy Zhang, who was introduced in season 3, will apparently continue to play Mel in future seasons.

Jensen Ackles

Despite Jensen Ackles’ busy schedule, each season has found a way to involve the actor, who plays Justin Hartley’s on-screen brother.

Sofia Pernas

The same goes for Justin Hartley’s off-screen wife, who has played his love interest on Tracker since the series premiere.
