AceShowbiz - The cause of Michelle Trachtenberg's death won't be determined. After the actress, who was known for her roles in iconic TV shows like "Gossip Girl" and "Buffy the Vampire Slayer," passed away at 39, her family declined an autopsy, The New York City Office of Chief Medical Examiner has confirmed.

Trachtenberg's unexpected death has left her fans and colleagues in mourning. Scores of her peers and past co-stars have taken to social media to express their grief and pay tribute to the talented actress.

"Michelle, listen to me. Listen. I love you. I will always love you," wrote Sarah Michelle Gellar, her "Buffy" co-star, on Instagram. Gellar continued in her heartfelt post, "The hardest thing in this world, is to live in it. I will be brave. I will live… for you."

Blake Lively, who worked with Trachtenberg on "Gossip Girl," described her late co-star as someone who was "electricity." Lively fondly remembered, "She laughed the fullest at someone's joke, she faced authority head-on when she felt something was wrong...[and] she cared deeply about her work."

Trachtenberg's career began early with roles in commercials at the age of three, followed by notable parts in "The Adventures of Pete & Pete" and "Harriet the Spy."

Her portrayal of Harriet M. Welsch earned her widespread recognition and praise. She continued to captivate audiences with memorable performances in "Buffy the Vampire Slayer," where she played Dawn Summers, and later as Georgina Sparks in "Gossip Girl."

Despite her professional successes, Trachtenberg had faced struggles in her personal life which became apparent in her recent social media posts. In January 2024, she addressed concerns about her health, stating, "I have never had plastic surgery I am happy and healthy."

Police sources revealed that Trachtenberg had recently undergone a liver transplant and may have suffered complications from it. Since her family declined an autopsy for religious reasons and there was no suspicion of foul play, her cause of death remains officially undetermined.

Michelle Trachtenberg's passing marks a significant loss for a generation of viewers who grew up watching her. Her magnetic presence and undeniable talent left a lasting impact on the entertainment industry and touched the lives of many.
