Homicide Squad detectives are continuing to appeal for information in relation to the murder of Christopher Phillips in Cheltenham in 1989.
The 42-year-old was found by his wife dead in their Gaybre Court home about 8.30pm on 1 May 1989.
Christopher had been seriously assaulted and suffered significant head trauma and lacerations.
At the time, he was wearing a track suit, which investigators believe indicated he was heading out for a run.
Christopher had no defensive wounds and police believe he was likely attacked from behind with a heavy blunt object.
Two knives were found next to Christopher, and these were also covered in blood.
It appeared as though the house had been ransacked; however nothing appeared to have been stolen.
However, there were signs of forced entry at a rear door of the house, as well as a show print located within the crime scene.
Detectives subsequently identified it as an ASICS Tiger Gel runner, possibly a size 9-10.
Christopher was an engineer by trade and had been described as a quiet family man who went jogging most nights.
Police have received information from a number of people over the years, however, his murder remains unsolved.
An initial $50,000 reward was offered for information about the case and in 2017 this was increased to $1 million.
Detectives are hopeful that over 30 years after his death, someone will be able to provide information about who was responsible for Christopher’s murder and why.
Police have also released a photo of Christopher.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report via the Crime Stoppers Victoria website(opens in a new window).
