Summary based on the NamUs case record (MP13428) and 6 other sources
In the quiet, early morning hours of February 1, 2011, in Lyndhurst, New Jersey, 13-year-old Sifeng Wu vanished from her hotel room, leaving behind a mystery that continues to raise concern. Sifeng, a visitor from China, was in the United States as part of a tour group, accompanied by seventeen other teenagers and three chaperones. She and a 15-year-old companion, Jiaqian Liu, were staying at the Quality Inn on Polito Avenue when they disappeared at approximately 1:20 a.m. The girls left their passports behind but took their personal belongings with them in backpacks, suggesting to authorities that they may have left of their own accord.

The initial investigation suggested that the two teenagers may have planned to travel to New York. This theory was supported when, shortly after their disappearance, one of the girls made contact with her parents back in China to assure them that she was safe. This communication provided a glimmer of hope, yet the specific whereabouts of Sifeng and Jiaqian remained unknown. The circumstances pointed towards a case of endangered runaways, a situation fraught with its own set of dangers and uncertainties, especially for two young girls in a foreign country. At the time of her disappearance, Sifeng was described as being 5'3' tall and weighing approximately 115 pounds, with black hair and brown eyes.

A significant development occurred in August of 2012, when Jiaqian Liu was located and found to be safe. However, this breakthrough did not lead to Sifeng's recovery, and she remains missing. The years since her disappearance have not yielded any new public information regarding her location or well-being. The case of Sifeng Wu is a somber reminder of a young girl who traveled to a new country, only to disappear into unknown circumstances. While her companion was fortunately found, the lack of resolution in Sifeng's case leaves her family and concerned individuals with unanswered questions and enduring apprehension for her safety.
