The mother of a young girl who vanished without a trace in Western Australia 40 years ago hopes a $1 million award may help solve the murder mystery. In a heartbreaking video, which has been shared onto the WA Police Force’s Facebook page on the anniversary of her disappearance, grieving mother Marion Flower, 77, is pleading for anyone with information to come forward.

According to a News.com.au report, 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 waiting to be picked up by a family friend but sadly was never seen again.

“She was very thoughtful and she had a lovely nature — she always smiled,” Marion recalls in the video, before adding: “If you are still out there, Lisa, somewhere, I still love you, I still love you to bits.”

She continued: “When Lisa first disappeared, I went into shock and ended up in the Collie Hospital in the middle of the night. I was screaming and could not stop myself.

“My only hope is after all this time that somebody is still alive that might know something because it’s a long time… a lot of things have changed.”

WA Police Force uploaded the video on their Facebook page with the caption: “Justice For Lisa. 12-year-old Lisa disappeared in Collie forty years ago today. Sadly, she has not been seen since. One million dollars is now on offer for information that leads to the apprehension and conviction of the person or persons responsible for the disappearance and suspected homicide of Lisa. Come forward if you know something.”

Facebook users were quick to comment on the emotional video, with one writing: “Heartbreaking. I hope there will be some answers soon so this lovely lady can put her daughter to rest, she has been living this nightmare for too long.” Another added: “Just heartbreaking. Someone must know something. I just pray that Lisa is found and returned to her grieving family.”

Earlier this month, the WA government promised a reward of $1 million for anyone with details about the tragic event in 1980.

“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 at the time.
