The CBS series Marshals, a Yellowstone spin-off, opened with the offscreen death of Monica Dutton from cancer. The move reportedly stems from a complex streaming rights agreement involving Peacock and Paramount.
In the premiere episode of Marshals, viewers learn that Monica Dutton, played by Kelsey Asbille, died from cancer tied to toxic waste contamination. The character was the wife of Kayce Dutton, portrayed by Luke Grimes, and her absence shifts the show toward a standalone procedural format.
