Tomorrow marks forty years to the day since the 13-year-old went missing while walking home from a friend’s house in the Auckland suburb of Henderson.
The 13-year-old was found strangled by pantyhose in the bush of the Waitakere Ranges on January 30, 1976.
Her murder remains unsolved.
A team of detectives have been working on the cold case since November and following fresh lines of inquiry – including interviewing people in Australia – in a bid to find her killer.
In video footage released by police Tracey’s family remembered the day she went missing.
Tracey’s sister Debbie said: ‘I can remember it clearly. I can remember coming back. She was about half an hour later than she was meant to be Dad and I were in the car; we just went around in Henderson in the town and we couldn’t find her’.
Debbie said going to the Doobie Brothers was the ‘regret of her life’.
