Nancy Liou was 15 when she vanished from downtown Toronto on January 27, 1999. She was supposed to attend Grade 10 exams at Monarch Park Collegiate but never arrived. Around 3 p.m., surveillance from her apartment building near Dundas Street East and Parliament Street captured her standing by the back door for about ten seconds, smiling as if recognizing someone, then running out of the building. Her father was asleep in the apartment at the time.

Nancy was described as outgoing and strong-willed, a frequent visitor to the nearby Regent Park Community Centre. The previous fall she had run away for 18 days but stayed in contact with family; by January 1999 family relations were reported as good. She reportedly told a relative she was going somewhere that day but gave no indication of an intent to leave permanently. At the time she was 5 feet 5 inches, about 121 pounds, with long dark brown hair with blonde streaks, brown eyes, a small black birthmark on her left cheek and a scar on the corner of her upper lip.

Her disappearance was initially treated as a runaway case and received limited attention, and years passed with no confirmed sightings or contact. Toronto Police renewed public appeals in June 2019, but Nancy’s whereabouts remain unknown and the investigation is still open. Did anyone in the Regent Park or Monarch Park area see Nancy or remember that day?
