The family and friends of Tanya Brooks are ensuring her memory stays alive as police renew calls for clues in her death.

Brooks’s body was found in a trench along the west side of St. Patrick’s – Alexandra School on May 11, 2009.

Police traced her movements until roughly 9 p.m. the night before her body was found.

Investigators believe she knew her assailant and that there are people who have information about her murder who have not spoken to police.

The 36-year-old Millbrook, N.S. native left behind five children.

Dozens of Brooks’s family members and friends gathered Tuesday in downtown Halifax to mark the anniversary of her death.

Brooks’s mother had organized memorial walks in her memory every year, until she passed away in the fall.

“She never recovered. My mother never recovered from her death,” says Stanley Brooks. “I lost my mom the same day I lost my sister.”

Brooks’s case has been added to 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.

Police are asking anyone with information about the case to contact them.
