NEW YORK (AP) — Michelle Trachtenberg, a former child star who appeared in the 1996 “Harriet the Spy” hit movie and went on to co-star in two buzzy millennial-era TV shows — “Buffy the Vampire Slayer” and “Gossip Girl” — has died. She was 39.
Police responded to a 911 call shortly after 8 a.m. at a 51-story luxury apartment tower in Manhattan’s Hell’s Kitchen neighborhood where officers found Trachtenberg "unconscious and unresponsive,” according to an NYPD statement.

Paramedics pronounced her dead at the scene. No foul play was suspected.
Trachtenberg’s family objected to an autopsy, the New York City’s Office of Chief Medical Examiner said Thursday. Because there was no evidence of criminality, the medical examiner’s office honored the objection, limiting its findings. Such objections are allowed by law. The cause and manner of her death are listed as undetermined.
“The family requests privacy for their loss," Trachtenberg's representative, Gary Mantoosh, said in a statement Wednesday.
Trachtenberg was 8 when she began playing Nona Mecklenberg on Nickelodeon’s “The Adventures of Pete & Pete” from 1994 to 1996 and then starred in the title role in the film adaptations of “Harriet the Spy” and “Inspector Gadget,” opposite Matthew Broderick.
“Michelle comes off as genuine because she really is a genuine kid. Everyone can identify with her,” said Debby Beece, president of Nickelodeon Movies in 1996.
In 2000 Trachtenberg joined the cast of “Buffy,” playing Dawn Summers, the younger sister of the title character played by Sarah Michelle Gellar between 2000 and 2003.
Trachtenberg thanked Gellar for speaking out against Joss Whedon in 2021, following abuse allegations made against the “Buffy” showrunner. “I am brave enough now as a 35-year-old woman to repost this,” she wrote on social media, and alluded to “his not appropriate behavior” she experienced as a teenage actor.
In 2001, she received a Daytime Emmy nomination for hosting Discovery’s “Truth or Scare.” Trachtenberg went on to recurring roles on “Six Feet Under,” “Weeds” and “Gossip Girl,” where she played the gang’s scheming nemesis, Georgina Sparks.
For her fan-favorite role, she was nominated as a TV villain at the Teen Choice Award in 2012. “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.”
She was one of the original series' stars to return for a pair of guest appearances in the 2021 “Gossip Girl” revival.
Blake Lively on Instagram on Tuesday honored her “Gossip Girl” co-star: "The world lost a deeply sensitive and good person in Michelle. May her work and her huge heart be remembered by those who were lucky enough to experience her fire.”
As if to cement herself in millennial culture, Trachtenberg made a cameo in Fall Out Boy’s music video for the “This Ain’t a Scene, It’s an Arms Race” alongside Seth Green.
Hollywood took to social media to mourn one of their own, one who had made the transition from kid star to teen queen to adult actor. “Buffy the Vampire Slayer” co-star David Boreanaz said on Instagram it was “so very sad.. horrible news.” Melissa Gilbert, who starred with Trachtenberg in the 1996 film “A Holiday for Love,” wrote on Instagram: “My heart aches for your family and all those who loved you so.”
Rosie O’Donnell, who starred alongside Trachtenberg in her “Harriet the Spy" debut, said her death was “heartbreaking:” “I loved her very much. She struggled the last few years. I wish I could have helped.” Glee star Chris Colfer remembered her this way: “Michelle was the absolute sweetest and one of the most supportive people I knew,” he wrote.
Trachtenberg's later credits included “Ice Princess” in 2005, playing a math prodigy and aspiring figure skater. The AP said it had “a good, though feeble, heart and the best of intentions” and said Trachtenberg was “mining the same nervous twitter from her kid-sister days on 'Buffy the Vampire Slayer.'”
The New York City-born Trachtenberg also appeared in the 2004 teen sex comedy “EuroTrip,” she co-starred with Zac Efron and Leslie Mann in 2009's “17 Again” and played a murderous stalker and abductor on an episode of “Criminal Minds.”
For “Killing Kennedy,” the 2013 film in which she played the wife of Lee Harvey Oswald, around 80% of Trachtenberg’s dialogue was in Russian. She had learned the language from her mother growing up.
Other credits included supporting roles in the films “Mysterious Skin” in 2004 and “Black Christmas” in 2006. She also starred on the NBC medical series "Mercy" (2009–2010) opposite Taylor Schilling. More recently, she hosted the true-crime docuseries “Meet, Marry, Murder” on Tubi.

U.S. President Donald Trump says Iran has proposed negotiations after his threat to strike the Islamic Republic as an ongoing crackdown on demonstrators has led to hundreds of deaths.
Trump said late Sunday that his administration was in talks to set up a meeting with Tehran, but cautioned that he may have to act first as reports mount of increasing deaths and the government continues to arrest protesters.
“The meeting is being set up, but we may have to act because of what’s happening before the meeting. But a meeting is being set up. Iran called, they want to negotiate,” Trump told reporters on Air Force One on Sunday night.
Iran did not acknowledge Trump’s comments immediately. It has previously warned the U.S. military and Israel would be “legitimate targets” if America uses force to protect demonstrators.
The U.S.-based Human Rights Activists News Agency, which has accurately reported on past unrest in Iran, gave the death toll. It relies on supporters in Iran cross checking information. It said at least 544 people have been killed so far, including 496 protesters and 48 people from the security forces. It said more than 10,600 people also have been detained over the two weeks of protests.
With the internet down in Iran and phone lines cut off, gauging the demonstrations from abroad has grown more difficult. Iran’s government has not offered overall casualty figures.
The Latest:
A witness told the AP that the streets of Tehran empty at the sunset call to prayers each night.
Part of that stems from the fear of getting caught in the crackdown. Police sent the public a text message that warned: “Given the presence of terrorist groups and armed individuals in some gatherings last night and their plans to cause death, and the firm decision to not tolerate any appeasement and to deal decisively with the rioters, families are strongly advised to take care of their youth and teenagers.”
Another text, addressed “Dear parents,” which claimed to come from the intelligence arm of the paramilitary Revolutionary Guard, also directly warned people not to take part in demonstrations.
The witness spoke to the AP on condition of anonymity due to the ongoing crackdown.

Iran drew tens of thousands of pro-government demonstrators to the streets Monday in a show of power after nationwide protests challenging the country’s theocracy.
Iranian state television showed images of demonstrators thronging Tehran toward Enghelab Square in the capital.
It called the demonstration an “Iranian uprising against American-Zionist terrorism,” without addressing the underlying anger in the country over the nation’s ailing economy. That sparked the protests over two weeks ago.
State television aired images of such demonstrations around the country, trying to signal it had overcome the protests, as claimed by Iranian Foreign Minister Abbas Araghchi earlier in the day.
China says it opposes the use of force in international relations and expressed hope the Iranian government and people are “able to overcome the current difficulties and maintain national stability.”
Chinese Foreign Ministry spokesperson Mao Ning said Monday that Beijing “always opposes interference in other countries’ internal affairs, maintains that the sovereignty and security of all countries should be fully protected under international law, and opposes the use or threat of use of force in international relations.”
German Chancellor Friedrich Merz condemned “in the strongest terms the violence that the leadership in Iran is directing against its own people.”
He said it was a sign of weakness rather than strength, adding that “this violence must end.”
Merz said during a visit to India that the demonstrators deserve “the greatest respect” for the courage with which “they are resisting the disproportional, brutal violence of Iranian security forces.”
He said: “I call on the Iranian leadership to protect its population rather than threatening it.”
Iran’s Foreign Ministry spokesman on Monday suggested that a channel remained open with the United States.
Esmail Baghaei made the comment during a news conference in Tehran.
“It is open and whenever needed, through that channel, the necessary messages are exchanged,” he said.
However, Baghaei said such talks needed to be “based on the acceptance of mutual interests and concerns, not a negotiation that is one-sided, unilateral and based on dictation.”
The semiofficial Fars news agency in Iran, which is close to the paramilitary Revolutionary Guard, on Monday began calling out Iranian celebrities and leaders on social media who have expressed support for the protests over the past two weeks, especially before the internet was shut down.
The threat comes as writers and other cultural leaders were targeted even before protests. The news agency highlighted specific celebrities who posted in solidarity with the protesters and scolded them for not condemning vandalism and destruction to public property or the deaths of security forces killed during clashes. The news agency accused those celebrities and leaders of inciting riots by expressing their support.
Canada said it “stands with the brave people of Iran” in a statement on social media that strongly condemned the killing of protesters during widespread protests that have rocked the country over the past two weeks.
“The Iranian regime must halt its horrific repression and intimidation and respect the human rights of its citizens,” Canada’s government said on Monday.
Iran’s foreign minister claimed Monday that “the situation has come under total control” after a bloody crackdown on nationwide protests in the country.
Abbas Araghchi offered no evidence for his claim.
Araghchi spoke to foreign diplomats in Tehran. The Qatar-funded Al Jazeera satellite news network, which has been allowed to work despite the internet being cut off in the country, carried his remarks.
Iran’s foreign minister alleged Monday that nationwide protests in his nation “turned violent and bloody to give an excuse” for U.S. President Donald Trump to intervene.
Abbas Araghchi offered no evidence for his claim, which comes after over 500 have been reported killed by activists -- the vast majority coming from demonstrators.

Iran has summoned the British ambassador over protesters twice taking down the Iranian flag at their embassy in London.
Iranian state television also said Monday that it complained about “certain terrorist organization that, under the guise of media, spread lies and promote violence and terrorism.” The United Kingdom is home to offices of the BBC’s Persian service and Iran International, both which long have been targeted by Iran.
A huge crowd of demonstrators, some waving the flag of Iran, gathered Sunday afternoon along Veteran Avenue in LA’s Westwood neighborhood to protest against the Iranian government. Police eventually issued a dispersal order, and by early evening only about a hundred protesters were still in the area, ABC7 reported.
Los Angeles is home to the largest Iranian community outside of Iran.
Los Angeles police responded Sunday after somebody drove a U-Haul box truck down a street crowded with the the demonstrators, causing protesters to scramble out of the way and then run after the speeding vehicle to try to attack the driver. A police statement said one person was hit by the truck but nobody was seriously hurt.
The driver, a man who was not identified, was detained “pending further investigation,” police said in a statement Sunday evening.
