The motive for the double murder of a brother and sister in Melbourne remain a mystery after 31 years, but detectives are hopeful someone will come forward.
A huge reward is being offered for information about the cold case murders of a brother and sister in Melbourne’s south-east more than 30 years ago.
Doris McCartney, 71, and Ronald Swann, 69, were found dead in their Keith Street home in Moorabbin on October 22, 1989.

Both had been assaulted but investigators have been unable to discover why they were killed.
But Victoria Police do believe someone came to the property to meet with Doris and there was an altercation.
‘Doris was a widower and her younger brother had moved into her Keith Street home to support her,’ Homicide Squad Detective Inspector Tim Day said on Tuesday.
‘From all accounts, they lived a quiet life and police have never been able to determine why they were both murdered.’
Police are now offering a reward of up to $1 million for information about who was responsible for their deaths.
‘There will be someone out there why knows why Doris and Ronald were killed and by who – 31 years is a long time to carry a secret,’ Inspector Day said in a statement.
