Twelve years after Brianne Wolgram disappeared from her hometown of Revelstoke, B.C., her family and the Missing Children Society are canvassing in 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.”

Wolgram was last seen at a Revelstoke 7-Eleven on the Labour Day Weekend in 1997. She had planned to meet a friend before heading out to a party. Wolgram never showed up.

Her car, a black 1989 Acura Integra with gold rims, was found five days later on a logging road south of the city.

More than a decade later, the official investigation into her disappearance has faded into the RCMP’s cold-case files, but Brianne’s parents Sheryl and Cliff Wolgram have never stopped looking.

This time of year is always difficult, Cliff said.

“It brings up the memories. It’s a little tougher on this weekend than any other time of the year,” he said. “Christmas is tough too.”

Hundreds of posters have been posted in an effort to breathe new life into the investigation. The Wolgrams are certain someone out there knows something.

“They’re probably still afraid to come forward and say anything, but … I want to bring my daughter home,” Sheryl said.

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