Darlene Yvonne Tucker was 16 when she left her Oakville, Ontario, home on February 14, 1983, following an argument with her mother after Darlene discovered she was pregnant. A student at General Wolfe High School, she first stayed with her boyfriend and his family, but that arrangement ended after a few weeks because of a dispute involving another young man she had been seeing in Toronto. The boyfriend’s father filed a missing persons report with the Halton Regional Police.

In the months after she left, Darlene made a few collect calls to her mother from a payphone in Huntsville, where the family owned a vacation trailer, and in 1985 there was a confirmed sighting of her working as a waitress in downtown Toronto. In 1987 she was seen in the Haliburton or Huntsville area with her friend Jinisina Jan Stonehouse, who had disappeared from Oakville in August 1983; that sighting is the last confirmed contact for either girl. Police have said they do not believe the two met with foul play and have raised the possibility they may be living under new identities. Darlene never claimed the trust fund money that would have been available when she turned 18.
