I recently spoke about unsolved murders involving female victims and research disclosed there were eight such murders in the 1970s. All of these murders resulted from the victims hitchhiking.
The Riley/Jahnke and Rosewarne murders particularly stand out as they all happened on the Gold Coast and certainly put a damper on girls hitchhiking. I attended each of these crime scenes.
A decision to save money for partying proved fatal for Gabriele Ingrid Jahnke and her best friend, Michelle Anne Riley, who, on 5 October 1973, decided to hitchhike from Brisbane to check-out the night life in Surfers Paradise and Coolangatta.
While the pair had known each other for only two months, they’d become inseparable and were often seen together in pubs in the Brisbane area. Ms Jahnke and Ms Riley were last seen alive at Michelle’s home in Emperor Street, Annerley, about 5pm on 5 October 1973.
Eight days later, two children made the gruesome discovery of 19-year-old Gabriele’s decomposed body on the side of the Pacific Highway at Ormeau. Her body lay at the bottom of an embankment, and it looked as if she had been thrown. She was dressed in a black caftan-style dress with white flowers and a black bra, but no other underwear. Her dress had been pulled up, suggesting she may have been raped.
Eleven days after the discovery of Gabriele, her best friend’s body — 16-year-old Michelle Riley — was found in bushland off the Camp Cale Road at Loganholme. She too had massive head injuries and her clothes were pulled up. The killer had hurriedly tried to conceal her body by pulling some branches over it. Police at the time said one person — “a frenzied maniac” — was responsible for both murders.
The finding of the body Gabriele Jahnke
Is still vivid in my mind as it was dumped metres from the highway at Ormeau in long grass with no attempt to conceal it. Certainly, a chilling experience for me.
The bodies were badly decayed and prevented any evidence of rape to be established. Whilst some appear to be linked, police were unable to establish that a serial killer was responsible. Homicide detectives followed up several leads in the double murder case, but no arrests were made.
Just days after the double murder, police were given a third case — an 18-year-old Ipswich girl who was raped, stabbed and left for dead near Nerang. Police initially linked all three murders and focused their attention on the description of a man and his car wanted in relation to the stabbing attack. He was eventually caught, but to the disappointment of the investigators at the time, was found not to be connected to the Jahnke-Riley murders.
The pair weren’t the only ones to meet a violent death in the southeast corner of Queensland during the 1970s. They were in fact the third and fourth to endure such a gruelling end.
The murders began in July 1972, with the deaths of 18-year-old Robin Hoinville-Bartram and Anita Cunningham 19. The pair were hitchhiking from Melbourne to Bowen in northern Queensland to visit Ms Hoinville-Bartram’s parents when they disappeared near Coolangatta. Ms Hoinville-Bartram’s body was found four months later under a bridge at Sensible Creek, west of Charters Towers. She had been shot in the head with a .22 rifle. Ms Cunningham’s body has never been found, but there is not much doubt about her fate.
Ms Jahnke and Michelle were the next to be murdered, and then on 5 October 1973 — one year after Ms Jahnke and Ms Riley vanished — two Sydney trainee nurses, Lorraine Wilson and Wendy Evans, both 20, disappeared while hitchhiking from Brisbane to Goondiwindi after their car broke down. Their bodies have never been found.
Then there was Surfers Paradise teenager Margaret Rosewarne, 19, who was last seen alive trying to hitch a ride near her home to Burleigh Heads on 5 May 1976. Sixteen (16) days later, her battered body was found in grass in a West Burleigh cul-de-sac. She had been so savagely beaten that her forehead was pulped, both upper and lower jaws were broken and the top row of her teeth shattered.
Police were never able to pin anyone to the “hitchhiker” killings and avoided suggesting the evil acts had been committed by one serial killer. However, there was no denying the chilling common denominators. All eight women were under 21, all were hitchhiking in the Gold Coast-Brisbane area, they all suffered serious head injuries, it appears they were all sexually assaulted, and in most cases, there was little effort to hide the bodies.
