The CBS drama Tracker delivered another intense episode on Sunday, March 29, 2026, with Season 3 Episode 14 titled “The Field Trip.” The episode brought together the show’s regular cast alongside several guest stars who played key roles in the missing child case. Here is a complete look at the actors and characters who appeared in this week’s episode.
The story followed Justin Hartley as Colter Shaw, who traveled to Milwaukee, Wisconsin, to help a desperate father find his 8-year-old son Alex. The boy disappeared during a school field trip at an aquarium after a fire alarm caused chaos. What seemed like a simple missing child case quickly turned into a race against time as Colter uncovered dark secrets about a neighbor who had been watching the family.
Main Cast Returns for Another Intense Case
Justin Hartley led the episode as Colter Shaw, the lone-wolf survivalist who uses his tracking skills to find missing people for rewards. Hartley has been with the series since its debut in 2024 and continues to anchor the show as both star and executive producer.
Fiona Rene appeared as Reenie Greene, Colter’s attorney who handles the legal side of his reward business. In this episode, Reenie worked on a separate case involving a wrongful death lawsuit. She met with Kurtis Lauper, a former project manager who had evidence of a construction company using contaminated materials. Rene has been a series regular since Season 1.
Chris Lee played Randy, Colter’s tech expert who helps track down information on suspects. Randy was promoted to series regular for Season 4, and his role in Episode 14 proved crucial when he hacked into a digital photo frame to locate the kidnapper’s cabin. Lee joined the show in Season 3 after the departure of original cast member Eric Graise.
Cassady McClincy Zhang portrayed Mel Day, Reenie’s new assistant who joined the team earlier in Season 3. Zhang is known to TV audiences for playing Lydia on The Walking Dead for three seasons. Mel has a background in criminal justice and previously worked for a district attorney before coming to work with Reenie.
Kathleen Robertson appeared as Maxine, the attorney who brought Reenie onto the class action lawsuit. Robertson joined the cast in a recurring role this season, and her character continues to push Reenie into deeper waters with the corporate case.
Guest Stars Bring the Missing Child Case to Life
Jon Beavers played James Clark, the father of missing 8-year-old Alex. Beavers brought intensity to the role of a desperate parent who grew frustrated with the police investigation and demanded answers. His character followed Colter around Milwaukee, sometimes getting in the way but always driven by fear for his son.
Beavers currently stars as Agent Billy Pace in the Hulu series Paradise. He also appeared in This Is Us alongside Justin Hartley, giving fans a connection between the two shows. His other credits include Kevin Costner’s Horizon: An American Saga, Animal Kingdom, and The Fresh Beat Band.
Elyse Levesque played Sara Clark, Alex’s mother who hired Colter to find her son. Levesque is known for her roles in Stargate Universe, Orphan Black, and Ready or Not. She worked with Beavers to portray a couple whose worst nightmare came true when their son disappeared during a simple school trip.
Luvia Petersen portrayed Detective Monroe, the Milwaukee police officer investigating Alex’s disappearance. Petersen has appeared in Continuum, Ghost Wars, and Riverdale. Her character initially thought Alex wandered off but accepted Colter’s help after realizing the case was more complicated.
Brittany Willacy played Sylvia Sloane, the museum custodian who became an early suspect. Sylvia had lost custody of her children after a psychotic break and worked at the museum to earn money for her legal fight. Willacy brought sympathy to a character who was simply in the wrong place at the wrong time.
Keon Lyn appeared as Mike, Sylvia’s friend who got into a physical fight with James Clark outside her house.
David Havasy had a role in the episode, though his character name was not specified.
The Actors Behind the Kidnapper and Teacher
The episode featured two key characters who drove the central mystery. The identity of Alex’s teacher, Mr. Brooks, and the neighbor Noah created the twists that kept viewers guessing until the end.
The actor playing Mr. Brooks was not named, but the character played a crucial role. Brooks had tutored Alex after school and discovered drawings the boy made, including one of a house with a yellow door. When Alex went missing, Brooks went to confront the neighbor and ended up injured after being struck with an axe.
Noah, the neighbor who took Alex, also appeared without a named actor. Randy discovered Noah had a criminal record and had been reported for loitering near a preschool. He had gained the family’s trust by teaching Alex chess while secretly watching the boy through a telescope aimed at his bedroom window.
Recurring Characters and Episode Connections
Elyse Levesque and Jon Beavers both have connections to Justin Hartley beyond Tracker. Beavers worked with Hartley on This Is Us, while Levesque appeared in Smallville, where Hartley played Green Arrow for several seasons. The episode gave fans of both shows a reason to appreciate the casting choices.
Chris Lee’s character Randy continued to prove essential to Colter’s success. In this episode, Randy hacked a digital photo frame to track Noah to a cabin in a local marsh. Without Randy’s tech skills, Colter would not have found Alex in time.
Fiona Rene’s Reenie storyline connected to a larger arc about corporate corruption. She convinced Kurtis Lauper to hand over evidence showing a construction company used contaminated materials that made workers sick. The case pointed to wrongful death, witness intimidation, and obstruction of justice.
