More money is being offered by the state government to progress a 19-year old cold case mystery in Northbridge.
It was in the early hours of November 10, 1998 when 19-year old mother-of-two Lisa Jane Brown vanished and and now a $250,000 reward is on offer for clues into her disappearance.
Police Minister Michelle Roberts today announced the increase today.
“Lisa Brown was a mother of two young children; she was also a daughter and a sister.
“Her killer remains at large and her family deserve answers," said Ms Roberts.
The last person to see her was her boyfriend, who said she'd walked down Brisbane street about 12.30am before she turned into Palmerston street.
Police believe she was met with foul play, and investigators have revealed they now have fresh clues.
"We believe there's an opportunity by putting in front of the community a reward of this nature, will give us even further information," said Police Commissioner Chris Dawson.
Lisa's family has also urged the community to come forward with any information.
“Obviously people must know something about what happened to Lisa," said Lisa's father Terry Brown.
"We’ve been waiting 19 years now for answers and really would like some sort of closure. If anyone does know anything please help the police and call Crime Stoppers.”
