The entertainment community is mourning the loss of actor and stand-up comedian Alex Duong, who passed away on March 28, 2026, at the age of 42. Known for his sharp wit on stage and his recurring role on the long-running CBS police drama Blue Bloods, Duong died at Saint John’s Health Center in Santa Monica, California, after a year-long fight with a rare and aggressive cancer. He was surrounded by his family, including his wife Christina and their five-year-old daughter Everest.
Duong’s journey from the Dallas comedy circuit to Hollywood sets was marked by perseverance and a deep connection to the community of performers who supported him until the very end. His death has prompted a look back at the roles he played, both on screen and off, and the quiet strength he showed during his illness.
Who Was Sonny Le on ‘Blue Bloods’?
For viewers of Blue Bloods, Alex Duong was best recognized as Sonny Le, a recurring character who appeared across multiple seasons of the show. Sonny Le was portrayed as a Vietnamese gang leader and criminal whose path crossed with Donnie Wahlberg’s character, Detective Danny Reagan.
Duong first appeared as Sonny in Season 12, Episode 7, titled “USA Today,” which aired in November 2021. In that episode, Danny Reagan worked to take down a local gang, with Sonny Le serving as a key figure in the criminal network. The character left a strong impression, leading to his return in Season 13, Episode 8, called “Poetic Justice,” which aired in December 2022.
The episode “Poetic Justice” saw Danny Reagan investigating a gang attack with a surprising motive, bringing him back into conflict with the criminal from his past. The character of Sonny Le served as a memorable antagonist, giving Duong the chance to show his range beyond comedy. His appearances across the three seasons demonstrated his ability to hold his own against the show’s veteran cast members.
A Career Built on Laughter and Versatility
Before landing his role on Blue Bloods, Alex Duong had already built a solid reputation in Hollywood. He became a member of SAG-AFTRA in 2009 and spent nearly two decades appearing in a wide variety of television shows. His credits included comedies like Everybody Hates Chris, crime dramas such as Dexter, and soap operas like The Young and the Restless. He also had roles in 90210, Pretty Little Liars, and Jeff Ross Presents Roast Battle.
Duong’s talents extended behind the camera as well. He worked as a writer for Netflix’s Historical Roasts, contributing to the show’s sharp comedic tone. On the film side, he appeared in movies like Formosa Betrayed, The Beyond, and Sideways for Attention.
Beyond the screen, Duong was a dedicated presence in the Los Angeles stand-up scene. Beginning in 2021, he served as a door attendant at the iconic Comedy Store, a role that many comedians view as a rite of passage. He performed regularly at clubs across the city and was known for his quick wit and warm stage presence.
The Rare Cancer Diagnosis and the Comedy Community’s Response
Duong’s health struggles began in early 2025 when he was diagnosed with alveolar rhabdomyosarcoma, a rare and aggressive form of soft tissue cancer. The disease is typically seen in children and is very uncommon in adults. The first signs appeared when his manager noticed severe swelling and discoloration around his left eye. Doctors later discovered a malignant tumor blocking the blood flow to his optic nerve.
Over the course of his illness, Duong lost vision in his left eye completely. The cancer later spread to his spine and brain, causing seizures and severe pain. Despite undergoing intensive chemotherapy and radiation, his condition worsened. In February 2026, he became bedridden, and on March 27, he went into septic shock, leading to his death the following morning.
Throughout his treatment, the comedy world rallied around him. Fellow comedians organized benefit shows to help cover his medical expenses, which reportedly exceeded $400,000. One such event, held in August 2025, was titled with dark humor: “The Alex Duong Has Cancer In His Eye Comedy Benefit Show.” It took place at the Largo in Los Angeles and featured performances from well-known comedians including Ronny Chieng, Andrea Jin, and Atsuko Okatsuka.
Friends also set up a GoFundMe page to assist with medical costs, memorial services, and long-term support for his five-year-old daughter, Everest. In a final update on the page, Duong’s friend Hilarie Steele shared details of his final moments.
“He was comfortable and thankfully out of pain. Christina and Everest were able to see him last night, and he was alert enough to say goodbye to his little girl, whom he has treasured every moment since the day she was born.”

Alex Duong’s impact on those who knew him extended far beyond his filmography. He was known for his resilience, his willingness to support other comedians, and his dedication to his craft. In an interview with the Los Angeles Times in April 2025, he spoke about the support he received from fellow performers during his illness.
“Comedians always have each other’s backs when times are tough. We know how hard it is to pine and struggle and scrape by in this lifestyle, just so we can do these jokes and keep improving. It’s a beautiful thing to see in this world; it really is.”
Before his diagnosis, Duong had been planning a major tour across 41 states for 2025, with several dates scheduled alongside Ronny Chieng. Though those plans were cut short, his legacy remains in the laughter he brought to audiences and the roles he played on screen.
Duong is survived by his wife Christina Duong and their daughter Everest.
