The New South Wales police announced an $750,000 increase in the reward for information over the murders of three children from Bowraville in the early 1990s.
Around thirty years ago, four-year-old Evelyn Greenup, Clinton Speedy-Duroux, 16, and Colleen Walker, 16, disappeared from the northern NSW town over a five-month period from September 1990.
Today, the NSW Police Commissioner Mick Fuller and NSW Attorney General Mark Speakman announced the reward increase after a briefing with the families of the victims.
"The increased reward forms part of our commitment to providing justice - firstly to the victims and their families - but also to the entire Bowraville community," Mr Fuller said in a statement.
The three murders were originally being investigated as separate cases before being linked by the homicide squad.
A man, who can't be named for legal reasons, was acquitted of Clinton's murder in 1994 and of Evelyn's murder in 2006.
In 2018, the government argued in the NSW Court of Criminal Appeal that there was fresh and compelling evidence relating to the disappearance of Colleen, which could have potentially justified overturning the two acquittals and a new single trial on the three murder trials.
However, the High Court refused to grant special leave to the NSW government to appeal the decision.
Colleen was last seen at a party in Bowraville on a Thursday night. Her family reported her missing the next day after she failed to return home.
Although her body was never found, the NSW Coroner ruled that Colleen was dead and had most likely been murdered.
Three weeks later, four-year-old Evelyn vanished from her bed at her grandmother's home. Her body was found in bushland near Congarinni Road six months later.
Clinton was 16 when he disappeared from a party in January 1991. His remains, like Evelyn's, were located in bushland near Congarinni Road the following month.
