On the morning of May 2, 2025, six-year-old Lilly Sullivan and her four-year-old brother Jack disappeared from their home on Gairloch Road in the rural Lansdowne Station area of Pictou County, Nova Scotia. The property is surrounded by woods, steep banks and thick brush. The children had been kept home from school because Lilly had a cough; their mother saw Lilly peek into the bedroom that morning, and by 10 a.m. the siblings were reported missing.

A large-scale search followed immediately. More than 160 trained volunteers joined the RCMP, canine teams, drones and helicopters with thermal imaging to comb over five square kilometres of dense terrain. The search, which continued for days before being scaled back on May 7, turned up no trace of either child. Investigators initially said there were no immediate signs of abduction, and the lack of any clues or sightings has been described as baffling.

The Northeast Nova RCMP Major Crime Unit continues to lead an active investigation. Authorities have conducted 106 formal interviews, obtained judicial authorizations to review phone and banking records of people close to the children, and examined thousands of video files. A $150,000 reward has been offered for information leading to locating the children. Does anyone in the area remember seeing Lilly or Jack, or have information that could help bring them home?
