There are roughly thirteen hours in Dr. Sneha Anne Philip's life that no one has ever been able to explain. And twenty-five years ago today, the clock started ticking. It was September 10th, 2001. Sneha was a 31-year-old physician living with her husband in Lower Manhattan. That afternoon, she was captured on surveillance shopping inside Century 21. At 7:18 that evening, several purchases were made with her credit card at the store. No one knows where she went after that. And her shopping bags disappeared with her. Sneha's husband came home around midnight to an empty apartment, and by morning, there was still no sign of her. But there may have been one. At 8:43 the following morning, the security camera inside Sneha's apartment building captured a woman entering the lobby. She lingered near the elevators for several minutes before walking back outside. Sneha's husband thought the woman resembled her. But investigators couldn't really see her face enough to make a positive identification. And three minutes later, everything changed, at 8:46 a.m., the first plane struck the World Trade Center. In the confusion that followed, Sneha's family began to believe she may have gone toward the World Trade Center to help. She was a doctor and lived only a few blocks away, so the possibility wasn't difficult to imagine. But no one could actually place her there. And as investigators dug deeper into Sneha's life, they found other reasons to wonder whether her disappearance had begun the night before. She had recently lost a medical residency and was dealing with legal and personal problems. Her husband also told investigators that she sometimes stayed out overnight. Then came another complication. Sneha's brother initially told reporters that he had spoken with her on the morning of September 11th and that she was helping people near the World Trade Center. He later admitted that wasn't true. He had made up the story because he believed connecting Sneha to the events of that morning would keep attention on her disappearance. Years later, another curious piece was added to the story. An anonymous postcard appeared on PostSecret, a website where people mailed in secrets to be published without their names. Written across the front was a single sentence. “Everyone who knew me before 9/11 believes I’m dead.” There has never been anything connecting the postcard to Sneha, and no one knows who sent it. But the timing of her disappearance and the possibility that she could have vanished into the enormous confusion that followed on September 11th have made that little postcard part of the conversation surrounding her case ever since. In 2008, a New York appeals court officially declared that Sneha had lost her life at the World Trade Center on September 11th. Her name now appears at the National September 11 Memorial. But the ruling couldn't account for those thirteen missing hours. Maybe Sneha returned home that morning and the woman caught on camera really was her. Maybe she went toward the towers to help. Or maybe something entirely different happened after she walked out of Century 21 on September 10th, and the events of the following morning obscured her trail forever. Twenty-five years later, we still don't know what happened to Dr. Sneha Anne Philip. More info 👇
