McAndrew’s disappearance has never been solved and investigators believe there are people who know what happened to her.

“We hope the passage of time will encourage them to do the right thing and share what they know with police,” said Halifax Regional Police Const. Amy Edwards in a news release.

“It’s never too late to come forward and the smallest piece of information may be just what’s needed to progress the investigation into Kimberly’s disappearance.”

McAndrew was last seen wearing pleated navy slacks, a white short-sleeved Esprit T-shirt with red and green squares, a navy oversized cardigan, and jade green flat-heeled loafers.

Her case is also part of the Nova Scotia Justice Department’s Rewards for Major Unsolved Crimes Program, which offers up to $150,000 for information that leads to an arrest and conviction in certain cases.
