FACE down in her bed, Annette Mason was found bloodied and brutally beaten to death at only 15-years-old.
Police had suspects almost immediately.
A witness had seen a girl matching Annette's description being chased by a man outside where she'd been living.
The family, who live in the Caboolture and Bribie Island region, thought police had things under control - now 28 years later the family have spent their lives filled with anguish, tears and endless questions.
More than 600 witnesses were interviewed and an autopsy report revealed Annette had suffered serious head injuries after being bashed across the face with a blunt object.
Detectives also confirmed that it appeared no one had forced their way into the Toowoomba home on the day of the brutal murder.
In November 1991 police eliminated 13 suspects and a coronial inquest resulted in an open finding.
The family are now pleading with the public for answers as they reach their third and final inquest into their beloved Annette's death.
November 19 will mark 28 years since the tragedy and Annette's cousin Dani Andersen wants to find closure for family members she's grown up seeing in pain.
"It's so hard to see the pain continue for so long," she said.
"It's such a personal thing, everyone's comfort zones say 'it's awful, not something people wish to discuss or remember' but I refuse to let it fade away and let them get away with it.
"All I want is for my Aunty (Annette's mum) to see justice before she passes."
Dani said this was the last chance for people to come forward with information.
"The silence needs to end, someone knows what happened," she said.
"It's never too late to speak up.
"I know it wasn't a local incident but that doesn't mean that someone doesn't know. Any chance is worth it."
