The actress was known for a wide range of film and TV roles, including Buffy the Vampire Slayer and Gossip Girl.
Her first credited role came at age nine when she appeared in the classic 1990s Nickelodeon series The Adventures of Pete and Pete.
She then starred in a variety of children-orientated shows and movies before pivoting to more mature acting roles, including the part of Dawn Summers, the sister of Buffy, and antagonist Georgina Sparks on Gossip Girl.
After hearing the devastating news of Trachtenberg’s passing, fans have taken to social media and paid tribute.
One fan writes: “Ice Princess was one of my favorite movies growing up. This is devastating.”
Another adds: “May she rest in peace. Loved watching Buffy, such a great show.”
“This is heartbreaking. Eurotrip was one of my fav films as a teenager. She was so likable in everything I saw her in,” comments a third. “My thoughts are with family and friends.”
According to sources from the New York Post, Trachtenberg was found by her mother at around 8 a.m. on February 26 at One Columbus Place, a 51-story luxury apartment complex in Manhattan’s Central Park South neighborhood.
The NYPD confirmed the actress was found ‘unconscious and unresponsive’ by police and pronounced dead by EMS workers.
Trachtenberg recently underwent a liver transplant, according to sources.
The star’s death is not being treated as suspicious and cops state the city medical examiner will determine the cause.
In recent months, Trachtenberg had posted a series of troubling photos on Instagram in which she appeared gaunt and frail.
It led fans to take to social media and comment on her appearance.
In response to such comments, the actress told fans she was ‘happy and healthy’ and had never had plastic surgery.
