In the autumn of 2013, a 22-year-old female student named Kacie Aleece Peterson vanished from New York, New York. She was last seen on September 21, 2013, in the vicinity of Baruch Drive in Manhattan, where she was a student at the John Jay College of Criminal Justice. Originally from Colville, Washington, Kacie had a history of memory loss, which added a layer of complexity and concern to her disappearance. This was not the first time she had gone missing. In 2009, at the age of 18, she disappeared from her home in Washington and was later found in New York City with no memory of her identity or past. Her family had noted previous instances of memory lapses, and during her senior year of high school, she was diagnosed with dissociative amnesia following a seizure. Kacie's life before her disappearance was marked by both achievement and personal challenges. She was an accomplished ski racer in her youth and was recognized for her academic merits by the U.S. Air Force. Seeking a new beginning after her diagnosis, she moved to New York, where she graduated from high school in 2011 and enrolled in college. At the time she went missing, she was described as a vulnerable adult who might be in need of medical attention. It was thought that due to her amnesia, she might have traveled to the southeastern or southwestern United States. She was also known to sometimes use the alias "Kitai Ryu". For years, Kacie's case remained unsolved, a painful uncertainty for her family and friends. Despite efforts by law enforcement, including the Stevens County Sheriff's Office, her whereabouts remained unknown. Tragically, after more than a decade of being missing, it was reported that Kacie Aleece Peterson passed away on March 23, 2025, in New York City. Her family, who had been without answers for so long, received the devastating news, bringing a somber end to their search. Kacie was remembered as a bright and accomplished young woman whose life was profoundly affected by her medical condition. She was laid to rest with her mother in Colville, Washington. The circumstances leading to her death were not detailed in the available information, but the discovery concluded the long and heartbreaking mystery of the missing student from Washington.
