Two girls raped and murdered on beach after knocking on doors before Halloween

Two young girls, Patricia Leedie, 9, and Leanne Oliver, 10, who were out door-knocking to earn some pocket money in the days leading up to Halloween, were tragically raped and murdered on a beach.

While Oliver's parents were enjoying a Sunday afternoon barbecue in a neighbour's back garden, the girls decided to go door-knocking.

The friends were no strangers to odd jobs for a bit of cash - they had previously asked neighbours if they could do some chores in return for money. But on that fateful day on 29 October 1995, they didn't return home.

Both girls were last seen around 3pm that day. By 7pm, they were reported missing, and a massive search was launched.

The authorities scoured the area until midnight, then resumed the search at dawn, the Express US reports.

Alby Oliver, Leanne's dad, was the first one to discover the girls that morning, roughly 12 hours after they vanished. Their partially clothed bodies were found lying side-by-side in the sand dunes at Warana Beach.

Post-mortem examinations later revealed that both girls had been sexually assaulted, ABC reports. Police began questioning residents and attendees of the barbecue as they tried to piece together the events of the day and solve the double murder.

Shortly afterwards, a wallet belonging to 27 year old Paul Stephen Osborne, a labourer from Wurtulla, who had previously served time for sexually assaulting a teenager, was found on the beach near where the girls' bodies were discovered.

Osborne had been at the same barbecue as Leanne's parents on the day of the murders, and was later seen heading towards the beach. He was questioned by police on the very night the girls were found and charged with their murders immediately.

The brutal attack led to a public outcry, resulting in heightened security at Maroochydore Magistrates Court on the day of his trial.

At the same time, relatives of both girls and some family friends wept as they awaited the start of proceedings. As Osborne was led into the courtroom, attendees hurled insults at him, leading to many being ejected from the gallery, as reported by ABC.

Osborne pleaded guilty to all charges and was handed two life sentences for the murders and two 18-year sentences for the rapes. He remains a high-risk prisoner due to the gravity of his crimes.

Even after thirty years, the community of Warana, located north of Brisbane in the Sunshine Coast region of Queensland, Australia, continues to struggle with one of the most shocking crimes it has ever experienced. Osborne was recently denied parole and won't be eligible for release for at least another eight years.

When Supreme Court Justice Glen Williams sentenced him to two life terms for murder and two 18-year sentences for rape, he declared that Osborne should never be released.

Despite being eligible for parole in 2020, it was refused. Queensland Parole Board president Michael Byrne declared that Osborne would not be allowed to apply for parole again until at least 22 May 2032.

Byrne recognised the severity of the crimes, as reported by the Australian Broadcasting Corporation, highlighting the danger Osborne's release could pose to the public.
