Michelle Trachtenberg, the beloved actress known for her roles in "Buffy the Vampire Slayer" and "Gossip Girl," has died at the age of 39 due to complications from diabetes mellitus, as confirmed by the New York City Office of Chief Medical Examiner. Trachtenberg was found unresponsive in her Manhattan apartment on February 26, 2025, and was pronounced dead at the scene by paramedics.
The circumstances surrounding her death have drawn attention, particularly since the family had initially declined an autopsy for religious reasons. The medical examiner's office indicated that no foul play was suspected, and therefore, an autopsy was not performed. However, following laboratory test results, the cause of death was amended to reflect the natural causes stemming from her diabetes.
Trachtenberg's sudden passing has left many fans and colleagues in shock. The actress had a vibrant career that began at an early age, making her television debut in commercials at just three years old. She became a household name after landing a recurring role as Lily Montgomery on the soap opera "All My Children" and later starred in Nickelodeon’s "The Adventures of Pete & Pete." Her breakout role came in 1996 when she played Harriet M. Welsch in the film "Harriet the Spy," which was based on the classic children's novel.
In 2000, Trachtenberg joined the cast of the cult favorite series "Buffy the Vampire Slayer" as Dawn Summers, the younger sister of Sarah Michelle Gellar's character, Buffy. She appeared in over 60 episodes until the show's conclusion in 2003, becoming a significant part of its storyline and emotional depth. Her portrayal of Dawn resonated with many young viewers, making her a relatable figure during the show's run.
Following her time on "Buffy," Trachtenberg played Georgina Sparks on the hit series "Gossip Girl" from 2007 to 2012. Her character was known for her manipulative and unpredictable nature, further showcasing Trachtenberg's range as an actress. She also starred alongside Zac Efron and Matthew Perry in the comedy "17 Again" around the same time.
In the years that followed, Trachtenberg made guest appearances on various television series, including "House," "Weeds," "NCIS: Los Angeles," and "Sleepy Hollow." Most recently, she reprised her role in the "Gossip Girl" sequel series in 2023, delighting fans who had grown up watching her.
Her death has sparked tributes from fans and colleagues alike. Sarah Michelle Gellar, who portrayed her older sister on "Buffy," shared an emotional tribute on social media, expressing her love and admiration for Trachtenberg. Gellar wrote, "Michelle, listen to me. Listen. I love you. I will always love you. The hardest thing in this world is to live in it. I will be brave. I will live… for you."

Trachtenberg's family has requested privacy during this difficult time, emphasizing the need for space to grieve their loss. Her representative, Gary Mantoosh, confirmed the family's wishes, stating, "The family requests privacy for their loss. There are no further details at this time." This request reflects the family's desire to handle their grief away from the public eye.
The medical examiner's office revealed that Trachtenberg had recently received a liver transplant, although the reasons for this procedure remain unclear.
