Alex Duong, the Dallas-born comedian and actor who built a devoted following through his sharp stand-up and a string of memorable television appearances, died on March 28, 2026, at Saint John’s Health Center in Santa Monica, California. He was 42. The cause of death was septic shock, following a yearlong battle with alveolar rhabdomyosarcoma, a rare and aggressive soft-tissue cancer. He is survived by his wife, Christina, and their five-year-old daughter, Everest.
Born on March 20, 1984, in Dallas, Texas, Duong spent two decades carving out a reputation as one of the hardest working performers in Los Angeles comedy and television. He began his career in 2006 and never really stopped, accumulating credits across some of television’s most recognizable titles, including Everybody Hates Chris, The Young and the Restless, 90210, Mad TV, Dexter, and Pretty Little Liars. He was perhaps best known to mainstream audiences as Sonny Le, a recurring criminal and gang leader on the long-running CBS police procedural Blue Bloods, a role he played from 2021 to 2024. He also played the recurring role of Genghis Khan in the YouTube comedy series The Cost of Living, and appeared on Jeff Ross Presents Roast Battle, where his comedic instincts and fearless stage presence earned him new fans.
His final chapter was one of extraordinary courage. In early 2025, after experiencing persistent headaches behind his eye, Duong was diagnosed after his manager noticed the alarming swelling and discoloration around his left eye. The tumor was blocking blood flow to his optic nerve and was labeled extremely aggressive almost immediately. He lost vision in his left eye entirely, endured chemotherapy and radiation, and continued to face the financial pressures of navigating serious illness as a working performer, struggling at times to meet SAG-AFTRA guild minimums for health insurance coverage. As his condition progressed, tumors spread to his spine and pushed on his brain, causing seizures. Through all of it, friends and family described him as someone who held on fiercely, motivated above all else by the little girl waiting for him at home.
Alex Duong was 42 years old. He made people laugh, he made people feel seen, and he fought until the very end. That is worth remembering.
