Twelve years after Brianne Wolgram's suspicious disappearance, the Missing Children Society is canvassing her hometown of Revelstoke, B.C. this weekend in the hopes of drumming up new information.

"Someone knows what happened to Brianne," former police detective Dan Picken, an investigator with the society, said in a statement announcing the campaign.

"We hope that our efforts on the anniversary date will spark someone's memory of what they saw that weekend," and reach people who were vacationing there at the time, he said. "We have to keep trying."

Wolgram was 19 when she disappeared from Revelstoke on the Labour Day long weekend in 1998. She was supposed to meet a friend and head to one of the many parties organized for the holiday.

She was last seen that night at a convenience store in town. Her car, a black 1989 Acura Integra with gold rims, was found five days later on a logging road south of the city.

Her family and friends say they never stopped looking for her. They are urging anyone with information related to the case to come forward.

"It's been a hellish nightmare the last 12 years," said her parents, Sheryl and Cliff Wolgram. "She is in our thoughts every day."

Nelli Richardson, a family friend, said Brianne Wolgram's disappearance has affected the whole community.

"Brianne, wherever you are, be assured we love you and will not give up until we find out what happened that fateful night 12 years ago."

Anyone with information can contact the society's confidential hotline at 1-800-661-6160 toll-free; CrimeStoppers at 1-800-222-8477; or the Revelstoke RCMP at 250-837-5255.
