Halifax Regional Police continue to look for tips on the 12th anniversary of Tanya Jean Brooks' murder.
The 36-year-old's body was found in a basement window well of St. Patrick's-Alexandra School at 2:17 p.m. on May 11, 2009.
According to the province's crime rewards program, Brooks was known to frequent the Gottingen Street area.
The mother of five was last seen leaving the Halifax Regional Police Headquarters at about 8:20 p.m. on May 10, 2009.
"Investigators believe Tanya knew her assailant(s) and that there are people who have information that could help solve her murder," said HRP in a news release. "We hope that the passage of time will encourage them to do the right thing and come forward with what they know."
Police say even a small piece of information may help them advance their investigation.
Anyone with information is asked to contact police at 902-490-5016 or submit an anonymous tip through Crime Stoppers.
The case is also part of the Nova Scotia Rewards for Major Unsolved Crimes Program, which offers up to $150,000 for information leading to the arrest and conviction of the person or persons responsible. All calls to 1-888-710-9090 are recorded and those who come forward need to provide their name and contact information, and could be called to testify in court.
The family of Tanya Brooks will be hosting a virtual memorial on Facebook today starting at 11 a.m.
