The search for a girl last seen 29 years ago continues for a second day in a wooded area north of Barrie, Ont. as police hope new technology can provide clues to the cold case.

Police are acting on a tip received after releasing a video re-enactment in July of Nicole Morin's disappearance.

Approximately 50 officers are searching ditches along the north side of Horseshoe Valley Road in Springwater Township. They're focusing on the area between Gill Road and Old Second Road, and are planning to wrap up the search Thursday afternoon.

On Wednesday, police and cadaver dogs combed the ditches along Old Second Road, but didn't find anything.

Police searched the same area when Morin disappeared, but are hoping that new technology may unearth more clues.

Morin was 8 when she disappeared from her west-end Toronto apartment building the morning of July 30, 1985. She left her penthouse apartment at 627 The West Mall in Etobicoke, and headed to the ground floor to meet a friend to go swimming.

Police are unsure whether she made it to the lobby. At the time, she was wearing a coral bathing suit, and was described as 4-foot-2 with brown hair and brown eyes. Her ears were pierced and she had a small birthmark on the upper right side of her forehead. She weighed approximately 60 pounds.

If Morin is still alive, she's now 37 years old.

Anyone with details is asked to call Toronto police at 416-808-2200, or contact Crime Stoppers anonymously at 1-800-222-8477 (TIPS).
