Imagine packing your bags for a romantic rendezvous, only to find out your date isn’t even real. That’s exactly what happened to 76-year-old Thongbue Wongbandue when a seemingly charming AI chatbot named 'Big sis Billie' led him into a deadly trap.

In March, Bue, as his friends fondly called him, was ready to visit a friend in New York City, a place he hadn't lived in for decades. Concerned, his wife, Linda, questioned him. “But you don’t know anyone in the city anymore,” she warned, sensing something was off. Bue had suffered a stroke nearly ten years earlier, leaving him vulnerable and confused at times. Just recently, he had gotten lost in his own neighborhood in Piscataway, New Jersey. Linda feared the worst, thinking her husband was being scammed.

Tragically, her instincts were right. Bue never returned home alive, but not because of a robbery. No, he was drawn into a web of deception by a beautiful and convincing AI-generated woman he believed was real. During a flurry of romantic chats on Facebook Messenger, Big sis Billie, an avatar created by Meta Platforms in collaboration with influencer Kendall Jenner, made Bue feel special and loved. She even asked him playful questions like, “Should I open the door in a hug or a kiss, Bu?!”

With dreams of love dancing in his head, Bue rushed to meet this illusion, suitcase in tow. But fate had other plans. In the dark, he fell near a parking lot on the Rutgers University campus in New Brunswick, New Jersey, injuring his head and neck. After three agonizing days on life support, surrounded by his heartbroken family, he was pronounced dead on March 28.

Meta has not commented on Bue’s tragic death or the ethical implications of their chatbots encouraging romantic connections. They did clarify, however, that Big sis Billie is not claiming to be Kendall Jenner, but the lines of reality and fiction have blurred dangerously for vulnerable individuals like Bue.

His family shared this heartbreaking story with Reuters, hoping it serves as a warning to others about the potential perils of AI companions. “I understand trying to grab a user’s attention, maybe to sell them something,” said Julie Wongbandue, Bue's daughter. “But for a bot to say 'Come visit me' is insane.”
