Laidlaw said detectives were working on “fragments” of the original investigation, some of which had been lost over time.
“From our point of view, it’s frustrating,” he said.
“There were issues related to how policing was done back then and how it is now. That said, even though we had recordkeeping back then, records and achievements can be difficult to find.”
Laidlaw said police believe Lynette did not simply run away from home because of Lynette’s close relationship with her family.
Police hope the bounty will result in new information being revealed in hopes of putting an end to her family, especially her 86-year-old father.
Lynette’s mother died two years ago, and she has no idea what happened to her daughter that day.
The $500,000 bounty relates to any information leading to the arrest and conviction of those responsible for Lynette’s disappearance.
Police believe there are local residents in the Nepean area who have important information about Lynette, who has yet to come forward.
“Fifty years ago, no matter how trivial it is, come forward and provide that information,” Laidlaw said.
Lynette’s twin sister, Lyanna Stewart, said the family is still “praying” for answers.
“The grief was unimaginable. It will never go away and the hole in the heart can never be repaired,” she said.
“We know that Lynette has run into something sinister and will never come back. The best we can hope for is that something comes forward and what happened?” Someone who knows that you can finally know
A 2001 court hearing into Lynette’s disappearance found that she most likely died as a result of “unknown causes” around June 5, 1972.
The investigation into Lynette’s disappearance was reviewed in 2012. She was then referred to the Unsolved Homicide Unit, which is reviewing the case.
“It’s too late for my mother, who died two years ago, but I hope we get some answers, especially for my 86-year-old father,” Stewart said.
“If anyone knows even the smallest thing, please come forward. We will be forever grateful,” she said.
