Andrzej Popek, 55, of Mississauga, Ontario, disappeared after a visit to Crawford Lake Conservation Area in Milton in late April 2015. Records differ slightly on the date: some list April 28, 2015, while more detailed notes say he was last seen on April 27. His vehicle was found unattended in the conservation area parking lot on April 28, tying his last known movements to that location.

Andrzej was described as about 5 feet 10 inches and 150 pounds with brown hair and brown eyes and a birthmark below his left eye. He was reportedly wearing a black jacket and black pants when last seen.

Peel Regional Police are listed as the investigating service; the case also appears in national and provincial missing-person listings (RCMP case 2015020929; Ontario ON-MM-2015-04-01670). The vehicle and conservation area remain the key facts connecting Andrzej to his final known movements. If anyone remembers seeing Andrzej at Crawford Lake or on nearby trails or roads that weekend, please contact Peel Regional Police or Canadian Crime Stoppers.
