If you've spent any time roaming the gritty, rain-slicked streets of Chicago’s 21st District via your television screen, you know Detective Hailey Upton. She’s the one with the piercing stare and the moral compass that occasionally spins out of control but usually lands on "do the right thing, no matter the cost." For seven years, she was the heartbeat of Chicago P.D., taking over the massive void left by Sophia Bush’s Erin Lindsay and somehow carving out a legacy all her own.
But who is the woman behind the badge?
Tracy Spiridakos is the actress who brought Hailey Upton to life, starting as a recurring guest in Season 4 before becoming a permanent fixture in the Intelligence Unit. Honestly, it’s hard to imagine the show without her now, but as of 2024, the "Upton era" has officially come to a close.
The Woman Behind the Badge: Meet Tracy Spiridakos
Tracy isn't actually from Chicago. She’s a proud Canadian, born in Winnipeg, Manitoba, to Greek-born parents. If you’ve ever noticed her effortless composure during high-stress scenes, it might be because she’s been at this a long time.
She grew up in a family of restaurant owners—George and Anastasia Spiridakos—and actually spent a chunk of her childhood (from ages four to nine) living in Skala, Greece. She’s fluent in Greek, which is a fun fact most casual fans don't realize. After moving back to Canada, she eventually caught the acting bug, headed to Vancouver, and the rest is basically TV history.
Before she was a detective, Tracy was actually a sci-fi darling. You might recognize her as Charlie Matheson from the J.J. Abrams-produced series Revolution. She spent two seasons carrying a crossbow and fighting for survival in a world without electricity. It was that role that really proved she could handle the physical and emotional demands of a lead character in a major network drama.
Why Did Tracy Spiridakos Leave Chicago P.D.?
It’s the question that’s been haunting the One Chicago forums for months. Why walk away from a hit show?
The truth is actually pretty simple, though it was a "very, very hard" decision for her to make. Tracy told Variety that she actually decided to leave at the end of Season 10. She reached out to showrunner Gwen Sigan and the legendary Dick Wolf to let them know she wanted one final year to wrap up Hailey’s story.
She wasn't pushed out. There wasn't any behind-the-scenes drama (that we know of).
Basically, she was just curious about what else was out there. After 140 episodes, she wanted to see what other characters she could play. "I was just curious what was out there for me and wanted to switch it up," she explained in interviews. You've got to respect the hustle—sometimes you just need a change of scenery after seven years in the same office.
How Hailey Upton Said Goodbye
The Season 11 finale, "More," was a doozy. If you were worried they’d kill her off, you weren't alone. Chicago P.D. isn't exactly known for "happily ever afters" (RIP Al Olinsky).
But Hailey’s exit was surprisingly... hopeful? After a brutal showdown with a serial killer and saving Sergeant Hank Voight’s life, Hailey realized she was drowning in the trauma of the job. She’d lost her husband, Jay Halstead (played by Jesse Lee Soffer), to a job in Bolivia. She’d been living in a house full of ghosts.
In her final moments, we see her:
- Searching for jobs at the FBI, FEMA, and the DEA.
- Having a raw, tear-jerking conversation with Voight about needing more for herself.
- Getting into a taxi and heading toward O’Hare International Airport.
When the driver asks where she’s going, she just smiles. We don't get a destination. It’s open-ended. It’s the kind of closure that leaves the door cracked just a tiny bit in case she ever wants to return for a guest spot.
Life After Chicago: What’s Next for Tracy?
So, where is the woman who plays Hailey Upton now?
As of early 2026, Tracy is staying busy. She’s transitioned from the police procedural world into a brand-new lead role. She’s starring in a series called Anna Pigeon, based on the popular mystery novels by Nevada Barr. It’s a total shift—trading the dark alleys of Chicago for the vast, rugged wilderness of the National Park Service.
It feels like a full-circle moment for her. She’s back to playing a fierce, capable woman in a high-stakes environment, but with a lot more trees and a lot less paperwork.

Final Thoughts for the Fans
Losing Hailey Upton was a hit to the Chicago P.D. family. She was the one who could go toe-to-toe with Voight without flinching. She brought a vulnerability to the team that felt real—mostly because Tracy herself admitted she’s not great at being vulnerable in real life and used the character to practice it.
If you're missing your favorite detective, the best way to support Tracy is to follow her new journey into the Anna Pigeon series. She’s proven she can carry a show on her shoulders, and honestly, we’re just glad she got a taxi ride out of town instead of a trip to the morgue.
