LINDA Mason has broken her silence for the first time about her younger sister's brutal and shocking murder more than two decades ago.
Ms Mason hopes her speaking out will pressure authorities to act and lead to a coronial inquest and justice for her slain sister.
Annette Jane Mason's badly beaten and partly naked body was found on November 19, 1989, concealed under a doona in the sunroom of a house she shared with two other women at 131 Anzac Ave, Toowoomba.
It is believed Miss Mason, 15, was murdered sometime between 5am and 7am before her body was discovered around 2.10pm.
No one has ever been charged over her murder.
Ms Mason, talking exclusively to The Chronicle, said it was still hard to comprehend what happened to her innocent young sister all those years ago.
She said the moment she learnt her sister had been murdered was still as vivid today as it was a quarter of a century ago.
"I remember the day we received the call saying Annette had been found . . . We were all devastated as you would expect. We were beside ourselves," she said.
"I remember crying the whole way to Toowoomba . . . I was heartbroken. It was beyond belief that something like this could happen."
Ms Mason said Annette's murder had profoundly affected her entire family in the years that followed.
She said the family was sick of suffering in silence and it was now time they received the answers and closure they craved.
"It is one thing to lose somebody, but then not to know why is the hardest part," she said.
"It is very disheartening after the many years waiting for an answer.
"We do not want pity or sympathy. We just want justice."
Ms Mason has urged Queensland Attorney-General Yvette D'Ath to reconsider ordering a coronial inquest after she rejected the family's call for one last week.
She said Annette deserved her day in court - even if it was more than two decades later.
"Annette no longer has a voice, and I do not want her death to be in vain," she said.
"I want her death to mean something.
"We would like to see an inquest held and someone held accountable for Annette's murder.
"If people were named as likely to have been involved, but the authorities could not prove it, then that would also give us closure."
