More heartbreaking details have emerged following the tragic death of Michelle Trachtenberg.

The beloved actress - known for her roles in hit shows like Buffy the Vampire Slayer and Gossip Girl - tragically passed away on Wednesday (Feb 26) at the age of 39.

Now, TMZ has reported that law enforcement sources have stated that Trachtenberg was found "unconscious and unresponsive" in bed at her Manhattan apartment by her mother, Lana.

Mom Lana then called the police and paramedics. Despite the immediate emergency response, Trachtenberg was pronounced dead at the scene.

“It is with great sadness to confirm that Michelle Trachtenberg has passed away. The family requests privacy for their loss,” Trachtenberg’s representative, Gary Mantoosh, confirmed in a statement.

Her death comes just months after reportedly undergoing a liver transplant, per the New York Post. Sources have also corroborated this news to PEOPLE.

While the official cause of death has yet to be determined, reports indicate that complications from her transplant may have played a role. However, authorities have stated there is no suspicion of foul play.

The New York City medical examiner is set to conduct an autopsy.

Law enforcement sources confirm that Trachtenberg was last seen alive around 10:00PM Tuesday and had recently been out with friends, showing no immediate signs of distress.

Trachtenberg 'Knew That Death Was A High Possibility', Friend Says

Trachtenberg was aware of the severity of her health issues in the months leading up to her death, according to her friend Amanda de Cadenet.

De Cadenet, a photographer and TV host, shared an emotional tribute on Instagram, writing: "I will not share the details of our conversations over the last 6 months, but you knew that death was a high possibility and I am only sorry that the outcome was not a better one."

In her initial post — later edited, per PageSix — she recalled a FaceTime call with Trachtenberg from a hospital bed. Though the actress’s appearance had changed, de Cadenet said her spirit remained intact.

"I will always remember you as the young vivacious woman I met when I took this photo of you … and seeing your face from the hospital bed when we FaceTimed recently, even though you did not look like you, your sweetness and humor were still alive," she wrote.

While de Cadenet chose to keep the details of their conversations private, she confirmed that Trachtenberg had come to terms with the seriousness of her condition and the possibility of a tragic outcome. She ended her message by wishing her late friend peace.

A Career That Defined a Generation

Born on October 11, 1985, in New York City, Trachtenberg began her career at just three years old.

She became known for appearing in some of the most popular shows and movies from the 90s and 00s -- making her a beloved star for millennials in particular as they grew up with her work.

Trachtenberg quickly rose to prominence with her role on The Adventures of Pete & Pete, before breaking into mainstream success with Harriet the Spy in 1996. She became a household name as Dawn Summers in Buffy the Vampire Slayer and later as Georgina Sparks in Gossip Girl.

Her film credits include EuroTrip, Ice Princess, and 17 Again, making her a staple in the early 2000s teen movie scene.

Heartfelt Tributes from Hollywood

News of Michelle’s passing has shaken the entertainment industry, with co-stars and fellow actors paying their respects.

Ed Westwick, who played Chuck Bass on Gossip Girl, wrote on Instagram Stories: “So sad to hear of the passing of @michelletrachtenberg. Sending prayers.”

Alyson Hannigan, who played Willow on Buffy, reflected: “I am deeply saddened by the news of Michelle’s passing. She brought a loving energy to the set of Buffy. My thoughts are with Michelle’s family and friends.”

Fellow Buffy actor Emma Caulfield added: “Our Buffy family lost a little sister today … Rest in peace lovely Mish Mish. You are loved.”

Final Social Media Posts and Fan Tributes

Just days before her passing, Michelle shared a throwback Instagram post of herself in a green dress, playfully captioning it: “I wanted to look like naughty #Tinkerbell.” The post has since been flooded with messages from devastated fans.

One commenter wrote: “Rest in peace. Thank you for raising us all with your endless iconic roles.” Another shared a heartfelt memory:

“I met you once at an airport about 18 years ago, coming back from deployment. You sat and talked with me for about 45 minutes when you didn’t have to while we were waiting on our flight to Chicago. I kept that picture all the way up until last year when my computer crashed and it was lost. Thanks for the conversation and the memory, Michelle. Fair winds and following seas wherever your eternity lies.”

Last year, fans had expressed concern over her appearance, with many speculating about her health. Michelle, however, fiercely defended herself, stating she was “happy and healthy.”

“Explain to me how I look sick,” she wrote in response to a follower’s comment last January. She also pushed back against those who still saw her as the child star they grew up with, saying: “Did you lose a calendar and not realize I’m not 14? I’m 38. How sad for you to leave such a comment.”

“I’ve received several comments recently about my appearance. I have never had plastic surgery. I am happy and healthy. Check yourself, haters," the actress wrote in a follow-up post.

Trachtenberg’s passing is a devastating loss for Hollywood and for the fans who grew up watching her on screen. While questions remain about the circumstances of her death, one thing is certain: her talent and impact will not be forgotten.

Michelle Trachtenberg's cause of death has been revealed.

The beloved actress - who first lit up screens as a child star in Harriet the Spy and later made waves on Buffy the Vampire Slayer and Gossip Girl - was found unresponsive on the morning of February 26 in her apartment near Columbus Circle in Manhattan.

Emergency services were called just after 8:00AM and pronounced her dead at the scene.

Authorities stated at the time that “criminality was not suspected,” and the medical examiner honored the family’s wishes against performing an autopsy, since there were no signs of foul play.

She was 39.

Now, the New York City Medical Examiner’s Office has confirmed to Deadline that the star died from natural causes “as a result of complications from diabetes mellitus.”

No autopsy was conducted, as her family objected for religious reasons, but toxicology tests provided further clarity in determining her cause of death.

Initially, the cause of death remained undetermined. However, once the toxicology results were in, the medical examiner officially ruled it a natural death.

A representative for the family issued a statement shortly after her death, saying, “The family requests privacy for their loss. There are no further details at this time.”

A New York City native, Trachtenberg’s career began at age three with TV commercials, followed by a recurring role as Lily Montgomery on All My Children. She shot to fame in the mid-90s starring as Harriet M. Welsch in Harriet the Spy, Nickelodeon’s first-ever feature film.

Her iconic portrayal of Harriet gained widespread acclaim, and Trachtenberg later recalled how Rosie O’Donnell, her co-star in the film, became her “biggest supporter” on set. “There was a lot required of me. I’m extremely grateful for the experience,” she told Entertainment Tonight in 2001.

Her quirky charm and sharp comedic timing made her a natural fit for Nickelodeon’s ’90s golden era, with roles in shows like The Adventures of Pete & Pete. She was later nominated for a Daytime Emmy for her hosting role in Truth or Scare.

In 2000, she joined the cult hit Buffy the Vampire Slayer as Dawn Summers, Buffy’s younger sister, a role she held until the series wrapped in 2003. Though some fans criticized the character’s teenage angst, Trachtenberg took the backlash in stride. “Most of the haters don’t have the guts to say things in person,” she said in an interview with Entertainment Weekly. “I rarely get the ‘Oh she ruined the show.’ I do get a lot of ‘Oh she was so whiny!’ Hi, were you a teenager?”

Her Buffy co-star James Marsters paid tribute following her passing, writing on Instagram, “My heart is heavy today. We have lost a beautiful soul. Michelle was fiercely intelligent, howlingly funny, and a very talented person.”

In 2004, she appeared in the cult comedy EuroTrip and the following year starred in Disney’s Ice Princess alongside Kim Cattrall. Cattrall also remembered her publicly, writing, “Rest in peace sweet Michelle,” while sharing a photo from the film.

But perhaps her most deliciously dramatic role came on Gossip Girl, where from 2008 to 2012 she played Georgina Sparks—the manipulative, unpredictable queen of chaos on the Upper East Side. “It’s kind of easy to be evil when you’re saying evil things. It’s definitely a lot more fun than playing the good girl,” she told Seventeen in 2009. “I love the reaction you get. I never understood why some actors don’t want to play villains or evil characters.”

Her work as Georgina earned her a Teen Choice Award nomination for Choice TV Villain in 2012. She reprised the role in Max’s Gossip Girl sequel series in 2023.

In her later years, she made appearances on series including House, Weeds, NCIS: Los Angeles, Sleepy Hollow, and even lent her voice to Robot Chicken.

In the days before her death, Trachtenberg was active on social media, posting nostalgic red carpet shots and reflecting on her past. In one caption, she wrote, “A memory, a magical night in #newyork. I remember feeling like Cinderella. Wishing everyone an ethereal weekend.”

Rosie O’Donnell called her death “heartbreaking” and said, “I loved her very much.” Fellow Nickelodeon alums Melissa Joan Hart and Kenan Thompson also expressed their condolences.
