Raymond Edmunds was born on March 12, 1944, at Queen Victoria Hospital in Melbourne, Victoria, Australia. 

Raymond Edmunds was active in Victoria, Australia, from the 1960s to the mid-1980s. In 1986, he was convicted of murdering 18-year-old Garry Heywood and the rape and murder of 16-year-old Abina Madill at Murchison East, near Shepparton. On February 10, 1966, both Heywood and Madill attended a rock concert but did not return home. A few days later, their bodies were discovered by two teenagers on a shooting trip. Heywood's body was found first, shot in the head with a rifle, while Madill's decomposed remains were located 200 meters away. She had been raped and bludgeoned to death.

Before these murders, Edmunds was known for a series of rapes in the 1970s and early 1980s. He earned the nickname "The Donvale Rapist" during this time. He was also given the name "Mr. Stinky" due to his strong body odor, which was thought to be a mix of dairy farm chemicals and manure.

The investigation into the murders involved fingerprint analysis. Sergeant Andrew Wall matched fingerprints found on Heywood's vehicle to Edmunds. This early fingerprint work was done manually, as technology for automated matching was not yet available. The evidence remained confidential to prevent the offender from adjusting his methods.

On March 16, 1985, Edmunds was arrested for unrelated indecent exposure charges. After he was fingerprinted, his fingerprints were matched to those from the Shepparton crime scene. At that time, fingerprinting was mandatory in New South Wales but not yet in Victoria.

Edmunds received two life sentences for the murders, with no chance of parole, along with 30 years for multiple rape convictions. He has faced allegations of additional murders and over 32 rapes but has maintained his innocence throughout. Police have attempted to use new laws to require blood samples from him for DNA testing as part of ongoing investigations related to other cases.
