Ristevski vanished on June 29 last year and police have been appealing to the public to come forward if anyone had seen the mother-of-one’s black Mercedes Coupe at the time of her disappearance.
News Corp reported police had had several calls about seeing the car recently and all were from the Mt Macedon area, where Ristevski’s body was found.
Search and rescue, SES and police from the missing persons unit have returned to the area to search for clues and will hone in on the stretch of road they believe the murderer would have driven before dumping Ristevski’s body.
“I have every confidence we will solve this case,” Detective Inspector Tim Day from the Missing Persons Squad told reporters.
While he refused to comment about the number of suspects being looked at or who they were, he did appeal to the public to come forward with any knowledge.
“There’s always going to be someone out there that knows more than we do,” he said.
If you have any information, please contact Crime Stoppers on 1800 333 000.
