One of two men who broke into a woman's home and raped her while her children were asleep is being hunted by police 30 years after the crime.
Two masked men broke into a Ballarat home on July 22 1990 and sexually assaulted a widowed mother of five young girls.
Brett Braddock, then 26, lived in the same neighbourhood as the woman, but wasn't connected to the attack until 2019 when cold case investigators asked him for a DNA sample.
He pleaded guilty and is currently serving a 12-year prison sentence over the rape and burglary, but the second man involved has never been identified by police.
Sexual Crimes Squad Detective Senior Constable Phil Drews said Braddock had not provided investigators "with any information about the other man involved" and other inquiries had failed to identify him.
He urged anyone who remembered Braddock, his friends, acquaintances and other information such as where he spent time, to come forward.
Detective Acting Inspector Mark Burnett said investigators had not given up and were determined to find the second person involved.
"This was a brutal incident that had significant and long-lasting impacts on our victim, which she has had to live with for three decades," he said.
"On the other hand, this man has lived those years with relative freedom and no repercussions yet for what he did."
