Halifax Regional Police believe there are people who have information that could help them solve a 20-year-old murder investigation.
Officers were called to Alfred Street in Dartmouth at 8:23 a.m. on September 10, 1998 after several young students found an unconscious woman in a wooded area behind Harbourview School.
When they arrived they found Margaret Elizabeth Hartrick with injuries to her head. She was rushed to the Queen Elizabeth II Health Sciences Centre where she died 8 days later.
Investigators believe she was assaulted in that wooded area.
Witnesses told police they heard arguing that morning and some reported hearing a car speeding off from the area.
"Investigators believe there are people who have information that could advance the investigation and hope the passage of time may encourage someone to do the right thing and come forward to police with what they know," said police in a news release.
Anyone with information who hasn't already talked to police is asked to call the Integrated Criminal Investigation Division at 902-490-5333 or submit an anonymous tip through Crime Stoppers.
This case is part of the Nova Scotia Department of Justice 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.
