On the morning of January 29, 1975, nine-year-old Simon Wilson left his family’s apartment in Toronto for his usual walk to Parkfield Public School and never arrived. He was described as having blonde curly hair and brown eyes, last seen wearing a green parka, brown pants and rubber boots.

Searchers concentrated on the nearby storm sewers and a creek where children played. Police, city workers and tracking dogs searched the tunnels; a suitcase containing food and drinks was found inside, and there were unconfirmed reports of a voice heard in the sewers. Three boys later found in the tunnels said they had been looking for Simon and had a suitcase with sandwiches and thermoses.

The active search ended on February 5, 1975, with no trace of Simon. A rumor circulated that a relative had taken him out of Canada. The Toronto Police Service lists the case as an open investigation. If anyone knew Simon, his routines, or saw him that morning, can you share what you remember?
