A man's been charged with murder after two bodies were found at Millicent yesterday.
The 53 year old reported the deaths to Police in Berri just after 10am and was later arrested.
But it's believed the bodies of an 84 year old woman and her 63 daughter may've been dead in their Plunkett Tce home since last Thursday.
It's also been revealed the younger victim was the man's wife.
It's unknown what he'd been doing since the killing but may have travelled through the Limestone Coast and Riverland areas including Mildura and Broken Hill.
The suspect's expected to face court today.
Major Crime detectives are assisting local police with the investigation and have undertaken a door-knock to try and piece together what happened.
If you have information or spotted the white 1998 Subaru Outback (rego S564AAS) the man was driving, please contact Police.
