Gossip Girl and Buffy star Michelle Trachtenberg died as a result of complications from diabetes, medical examiner says

Gossip Girl actress Michelle Trachtenberg died as a result of complications from diabetes, New York City’s medical examiner has said.

The 39-year-old, who was also known for Buffy the Vampire Slayer and Harriet the Spy, was found dead at her home in New York City after officers responded to a 911 call on 26 February.

According to a source quoted by Sky News’ US partner network NBC, she had recently received a liver transplant.

At the time of her death, officials said no foul play was suspected, and the medical examiner’s office had listed her death as “undetermined”.

Trachtenberg’s family had objected to a post-mortem, which the medical examiner’s office honoured because there was no evidence of criminality.

But the medical examiner’s office said in a statement on Thursday it amended the cause and manner of death for the actress following a review of laboratory test results.

Trachtenberg was best known for her role as Dawn Summers in Buffy, the younger sister of the title character played by Sarah Michelle Gellar between 2000 and 2003.

Between 2008 and 2012, she played Georgina Sparks on Gossip Girl – the malevolent rival of Blake Lively’s Serena van der Woodsen and Leighton Meester’s Blair Waldorf.

She also starred in the movie 17 Again, where she portrayed daughter Maggie O’Donnell, comedy film Eurotrip and the 2005 teen film Ice Princess.

In 2001, she received a Daytime Emmy nomination for hosting Discovery’s Truth or Scare.
