As Criminal Minds: Evolution charges into its 19th season, the long-running procedural is facing one of the biggest creative challenges in its history: what comes after Elias Voit?

For three seasons, Zach Gilford’s chilling serial killer mastermind dominated the series. He wasn’t just another unsub for the Behavioral Analysis Unit to hunt down. He became the center of the show’s mythology, a villain whose influence stretched far beyond individual murders and whose network of followers created one of the most ambitious storylines the franchise has ever attempted.

Now, with Voit behind bars and fully aware of the horrors he committed, Criminal Minds: Evolution is entering unfamiliar territory. Instead of focusing solely on capturing a killer, Season 19 is asking a far more complicated question: can someone responsible for unimaginable evil ever become useful again?

According to showrunner Erica Messer, that question lies at the heart of the season.

Speaking about Voit’s latest chapter, Messer explained that audiences are witnessing something the series has never truly explored before: the long-term evolution of a serial killer after capture.

“Voit’s entire journey is exciting because it’s something we haven’t been able to explore before,” Messer said. “By the time Season 19 rolls around, the man who was hiding in the dark, ashamed of himself, caught by the BAU, is now a household name.”

That change has transformed both the character and the series around him.

When Voit first emerged as Sicarius, he operated in shadows. His power came from secrecy. His victims disappeared without explanation, and his network thrived because nobody knew the true scope of what he had built.

Now everyone knows.

The public knows his name.

The media knows his crimes.

True-crime podcasts obsess over him.

Online conspiracy theories continue to spread.

And that notoriety creates an entirely new threat.

Season 19 explores what happens when a serial killer becomes famous.

Rather than disappearing into prison and fading from public consciousness, Voit has become the subject of endless fascination. Some people study him. Others romanticize him. Some even question whether authorities truly understood what happened.

For BAU Unit Chief Emily Prentiss, that public obsession may be almost as dangerous as Voit himself.

The emergence of online documentaries, podcasts, and conspiracy theories has created a strange cultural afterlife for the killer. Some theories even suggest the BAU somehow contributed to his rise, a prospect that threatens both the team’s reputation and its mission.

It is a storyline that feels particularly relevant in today’s media landscape, where true-crime content often walks a fine line between education and entertainment.

Season 19 appears determined to explore that tension head-on.

At the center of the debate is Dr. Tara Lewis, played by Aisha Tyler.

This year, Tara takes a leading role in interviewing Voit inside prison. Her goal is to better understand how modern serial killers think, operate, recruit followers, and evolve in a digital world.

But those interviews come with serious risks.

Every conversation forces Voit to revisit his crimes in extraordinary detail.

While the BAU hopes that information could help prevent future murders, others worry that documenting his methods may ultimately provide a blueprint for future killers.

That ethical dilemma becomes one of the season’s most compelling story engines.

Is knowledge worth the risk?

Can studying evil help stop it?

Or does giving a killer a platform only amplify their influence?

Tyler believes those questions connect directly to the original spirit of Criminal Minds.

“The original BAU thought you could understand how these minds work,” she explained. “We can prevent these kinds of things from happening in the future.”

For Tyler, the series has always been about confronting darkness so others do not have to.

“What I find compelling about the show is that some people have to get dirty so that other people can stay clean,” she said.

That philosophy has defined Criminal Minds since its earliest seasons, but Evolution pushes it further than ever before.

Because unlike previous unsubs, Voit is not dead.

He is not on the run.

He is sitting across from the BAU, talking.

And that creates a moral gray area that divides the entire team.

One of the most intriguing aspects of Season 19 is that every character sees Voit differently.

David Rossi, whose life was profoundly affected by Voit’s crimes, wants nothing to do with him.

For Rossi, redemption feels impossible.

Penelope Garcia, on the other hand, sees things through a more compassionate lens.

That doesn’t mean she forgives him.

But Garcia has always believed people are more complicated than simple labels of good and evil.

Kirsten Vangsness believes that complexity is exactly what makes the story compelling.

“She knows how he came up. She knows what happened to him,” Vangsness said about Garcia’s perspective.

According to the actress, empathy creates discomfort because it removes easy answers.

“It takes away the black and white,” she explained. “Then you’re just sitting in the gray.”

That gray area has become the defining theme of Evolution.

Viewers are constantly being asked whether they believe Voit.

Is he genuinely remorseful?

Has prison changed him?

Does he truly want to help?

Or is this all part of a larger manipulation?

The uncertainty extends beyond the characters to the audience itself.

Messer intentionally wants fans to experience the same conflict that exists within the BAU.

“I feel like in the best-case scenario, the fans all feel the way our characters feel,” she explained.

That means constantly questioning every word Voit says.

Even when he appears sincere.

Even when he appears broken.

Even when he appears helpful.

After all, he remains one of television’s most effective killers.

And killers survive by manipulating perception.

While Voit remains the emotional center of the season, Criminal Minds continues introducing fresh faces to keep the franchise evolving.

One of the most anticipated additions this year is Connor Storrie, whose appearance has generated significant excitement among fans.

Long before Storrie became a breakout star through Heated Rivalry, however, the Criminal Minds team recognized his potential.

According to Messer, Storrie was initially hired for a much smaller role.

That quickly changed.

“He was shooting a scene with A.J. Cook that I believe made our trailer,” Messer recalled. “There was such a presence about him, super genuine, super talented.”

The impression was so strong that producers expanded his role from one episode to a four-episode arc.

Remarkably, that decision happened before Heated Rivalry exploded into a global phenomenon.

As a result, the Criminal Minds cast jokingly feels like they discovered him first.

Aisha Tyler has been especially vocal about her admiration for the young actor.

“I think what’s really special and why people are connecting to Connor is not just that he’s talented, but he’s just a really nice person,” she said.

The actress described the Criminal Minds set as a supportive creative environment where everyone wants newcomers to succeed.

That atmosphere has helped the show maintain its longevity.

Now entering its 20th year on television, Criminal Minds remains one of the rare procedural franchises capable of reinventing itself while retaining its core identity.

Tyler believes that willingness to embrace new talent plays a major role in that success.

“We are making our 20th season,” she noted. “That’s unusual for any show anywhere.”

Even after two decades, the series continues finding fresh stories to tell.

Season 19 may be its boldest experiment yet.

Instead of presenting a straightforward battle between heroes and villains, Evolution is asking viewers to confront uncomfortable questions about justice, redemption, accountability, and human nature.

Can a monster change?

Should society care if he does?

And if someone responsible for enormous suffering can help save future lives, what do we do with that information?

Those questions do not have easy answers.

That is precisely why Criminal Minds: Evolution continues to stand apart from other crime dramas.

It understands that the most frightening mysteries are not always about catching killers.

Sometimes they are about understanding them.

And as Elias Voit begins the next chapter of his journey from prison, the BAU may discover that understanding him could be even more dangerous than hunting him ever was.

New episodes of Criminal Minds: Evolution Season 19 stream every Thursday on Paramount+, with Connor Storrie making his highly anticipated debut beginning June 11.
