Mother’s Day this weekend will yet again be a tragic occasion for one Nova Scotia mother who will mark the sixth anniversary since her daughter’s body was found.

The body of 36-year-old Tanya Brooks was found in a trench alongside St. Patrick’s-Alexandra School in Halifax’s North End in 2009.

Last seen leaving Halifax Regional Police Headquarters on Gottingen Street, investigators were able to trace Brooks’ movements until about 9 p.m. on May 10, but then the trail goes cold.

“Her last words to me, ‘Happy Mother’s Day’,” recalls her mother, Connie Brooks Adams of Millbrook, N.S.

This year, Brooks Adams will markanother Mother’s Day by marching in a memorial walk to remember her daughter.

“It just doesn’t get easier.”

Brooks was a mother to five children.

As they grow up, they are searching for answers, says Brooks Adams.

“(They say) ‘What happened to mom? What happened, you know, why’s she not around to see me play football,” said Brooks Adams.

They aren’t the only ones looking for answers.

The case is part of Nova Scotia’s Major Unsolved Crimes Program.Through that, the Department of Justice offers up to $150,000 for information that leads to an arrest and conviction in relation to the case.

"At this time, we don't have information to further this case,” said Halifax Regional Police spokesperson Cst. Pierre Bourdages.

“We do believe there are people that have information about what happened to Tanya that night and we are urging them to come forward,” he said.
