Yong Joo Pak was 45 when she was last seen in Manhattan on December 28, 1991. She was reported as 5 feet 1 inch tall, about 115 pounds, with black hair and black eyes. Reports place her last known location at a New York City shelter, but no specific shelter or circumstances around her disappearance are publicly described.

An official missing persons report was not filed with the NYPD Missing Persons Squad until January 30, 1992. The case was later entered into the National Missing and Unidentified Persons System on September 6, 2012, as MP17311.

Did anyone who stayed at or worked in Manhattan shelters in late December 1991 remember seeing Yong Pak or have information that could help fill in what happened?
