The Traitors‘ Alan Cumming hosts Oxygen’s The Killer Among Us, a new true crime series premiering on Sunday, May 17, 2026 at 7pm ET/PT. The series spotlights murders that take place in tight-knit communities and includes an episode about the murder of a Sarasota gallery owner who’s found posed like a sculpture.
Cumming serves as a producer, with Zak Weisfeld, Libby Richman, and Brian DeCubelli executive producing.
“Throughout the season, Cumming takes viewers down the duplicitous road of devious, double-crossing, and deadly stories of those slain by a member of their own circle. The series is a real-life ‘whodunnit’ that delves straight into the heart of communities where the unthinkable has happened, and no one knows why — or who is responsible,” reads Oxygen’s synopsis. “From small rural towns to an academic research lab to high-end art organizations, The Killer Among Us takes viewers across the country to examine communities once thick as thieves uprooted by tragedy.”
Additional season one episodes focus on the following:
- When a county treasurer is found murdered in her garage, Main Street becomes a crime scene where no one can trust their neighbor.
- A university for the deaf serves as a haven in Washington, DC. But when a freshman is brutally murdered, the student body is plunged into terror.
- When a bride-to-be enters a Yale University building to do research and vanishes, everyone within the ivy-clad walls becomes a possible suspect.
- A University of Kentucky football standout celebrates his 21st birthday when a gunshot cuts through the night and strikes him dead.
- At New York’s Metropolitan Opera, a violinist is murdered during intermission, leaving everyone in front of and behind the curtain under suspicion.
