Sean Sidi, a 19-year-old from San Francisco, California, was last seen on May 21, 2013. On the day of his disappearance, Sean visited a former teacher at the French American International School around 11:40 a.m. Surveillance footage shows him leaving the school on foot, but he was not seen afterward. He spoke with his father at around 1:30 p.m., mentioning that he was heading to Golden Gate Park by bus. His phone last pinged near the park at 2:00 p.m., after which all communication ceased.
Sean’s disappearance is particularly concerning due to his medical condition. Six months prior, he had suffered a traumatic brain injury that required significant medical treatment, including surgery to replace part of his skull. His family has expressed deep concern for his safety, as even a minor head injury could have fatal consequences without ongoing medical care. Sean was also wearing a black splint on his left arm at the time of his disappearance, further highlighting his vulnerable condition.
Despite extensive searches and efforts by his family and law enforcement, no substantial leads have emerged. Sean’s case remains unsolved, and his family continues to seek information that could help bring him home.Last Seen: May 21, 2013
