Why the show kills off characters: creative choices and cast reactions
Showrunner Erica Messer has acknowledged the emotional toll of writing out beloved figures. She says the team never truly prepares the audience for a sudden loss. The intent, she explains, is to serve the story and the characters involved.
Cast members have expressed mixed feelings about those choices. Adam Rodriguez praised the series as a dream job and admitted no one wants the show to end. He has also suggested that character deaths should feel earned and meaningful for viewers.
Not every departure was planned far in advance. Some actors decided to step away and the writers had to craft exits that fit the show’s tone.
Most heartbreaking departures from Criminal Minds — ranked by impact
The following episodes left lasting impressions. Each loss changed the BAU in its own way.
Haley Hotchner — the murder that stunned the team
Hotchner’s family tragedy became one of the franchise’s darkest moments. The killer known as The Reaper targeted Hotchner’s wife in a scene that forced the BAU to listen helplessly over the phone.
- Emotional fallout: The sequence deepened Hotchner’s struggle with the job.
- Legacy: The event is often cited as the show’s most harrowing blow to a main character.
Maeve — a brief romance cut short
Reid’s relationship with Maeve ended abruptly when her stalker found and murdered her. The short-lived romance added vulnerability to Reid’s storyline.
- Actress: Maeve was played by Beth Riesgraf.
- Effect: The loss underscored the dangers characters face even off-screen moments.
Jason Gideon — a legendary agent killed off-screen
Though Mandy Patinkin left the series years earlier, the creative team later revealed Gideon had been murdered. The death occurred off screen and was tied to a killer from a past case.
- Impact on the BAU: His off-screen fate haunted former colleagues.
- Narrative choice: The reveal reopened old investigations and regrets.
Erin Strauss — poisoned by a cunning adversary
Assistant Director Erin Strauss, portrayed by Jayne Atkinson, survived political battles with the BAU but met a tragic end. She was poisoned by an unsub identified as the Replicator.
- Season: The poisoning took place in season eight.
- Aftermath: Strauss’ death reshaped leadership dynamics at the BAU.
Will — a recurring ally whose return ended suddenly
Josh Stewart played Will intermittently since 2007. In 2024 he confirmed he would not return for further seasons. The character later collapsed during an episode and died in 2025, a turn that surprised many fans.
- Role: Will was a trusted friend to the team.
- Reaction: Viewers debated whether the death served the story or the constraints behind the scenes.
Roxy — the heartbreaking loss felt at home and on screen
In the 2026 two-part season opener, Luke Alvez mourns a private loss. It is revealed at the episode’s close that his dog, Roxy, had to be euthanized. The moment added quiet grief to an otherwise case-driven plot.
- Emotional weight: The scene reminded viewers the team lives with personal pain outside their cases.
- Actor response: Adam Rodriguez has spoken about how the show balances grief and duty.
How episodes use deaths to evolve characters and plots
Criminal Minds often leverages loss to deepen a character’s arc. A death can trigger an investigation, uncover secrets, or force a character to change direction.
These choices can split fans. Some praise the series for realistic stakes. Others wish fewer beloved characters would be sacrificed for shock value.
Notable behind-the-scenes notes and timing of departures
- 2020 marked the original series finale before the revival.
- Paramount+ brought back the brand with Evolution, which expanded storylines and risks.
- Guest appearances by returning cast members have been used sparingly to preserve drama.
Where the BAU stands now and what fans watch for next
After nearly two decades of cases, betrayals and losses, the show continues to balance procedural elements with emotional stakes. Fans closely monitor cast updates and showrunner interviews for clues about who may be next.
With the revival still delivering surprises, the series remains a study in how long-running dramas handle mortality within their worlds.
