Actress Michelle Trachtenberg died as a result of complications from diabetes, according to New York City’s medical examiner.
The office said in a statement that it amended the cause and manner of death for the 39-year-old New York City native following a review of laboratory test results.
Trachtenberg, who was known for her roles in TV shows Gossip Girl, Buffy The Vampire Slayer and Six Feet Under, as well as films like Harriet the Spy, Eurotrip and 17 Again was found unconscious and unresponsive in her luxury apartment tower in Manhattan on 26 February.
Officials at the time said no foul play was suspected, and the medical examiner’s office had listed her death as “undetermined.”
Trachtenberg’s family had objected to an autopsy, which the medical examiner’s office honored because there was no evidence of criminality.
Sarah Michelle Gellar and Blake Lively were among the celebrities who mourned Trachtenberg when her death was announced.
Her Buffy the Vampire Slayer co-star David Boreanaz said it was “so very sad.. horrible news”, while the show’s Alyson Hannigan, who played Willow, wrote on her Instagram: “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.”
