It is hoped a $1 million reward to solve a West Australian murder mystery will finally “end four decades of heartache” for a girl’s family.
Lisa Marie Mott, 12, was last seen about 8.30pm on Forrest Street in the suburb of Collie on October 30, 1980.
She had just left the basketball courts and was expecting to be picked up by a family friend to go home.
“We hope that the announcement of a $1 million reward will encourage someone to come forward with information that can end four decades of heartache for her family,” Police Minister Michelle Roberts said in a statement on Sunday.
The government might consider recommending protection from prosecution or a pardon for any informant who helps land a conviction for whoever is responsible for Lisa’s disappearance and suspected homicide.
Police strongly believe someone in the community has information about the then-12-year-old’s disappearance.
“We want that person to come forward,” Superintendent Rod Wilde said.
“This is an opportunity to give closure to Lisa’s mum.”
There have been many theories about what happened to Lisa, including that serial killer David Birnie was involved.
He took his own life in prison in 2005.
Ms Roberts said cabinet approved the large reward after consultation with the WA Police Force.
“The success of the police in the Claremont (serial killer) case shows that with sufficient resources and determination, cold cases can be solved,” she said.
“Arrests can still be made, even after many years, and convictions secured.
“Neither the police, nor the government gives up on any of these cases and we want to encourage the community not to give up either.”
The Claremont serial killer case also spanned decades, with former Telstra technician Bradley Robert Edwards finally convicted of murdering child care worker Jane Rimmer and solicitor Ciara Glennon in September.
He was acquitted of killing secretary Sarah Spiers, whose body has never been found.
