Police are investigating a murder-suicide in a plush beachside suburb known for its sparkling water, boats, restaurants and fancy houses.
The blast of violence started on Tuesday about 1.30pm when police attended an address on Kibby Ave in Glenelg North, about 11km west of the Adelaide CBD.
The police found an 88-year-old man deceased at the home, but they were unable to establish the cause of death and investigations continued.
Then on Wednesday about 4.10am, the police were called to the same address, where a 63-year-old Glenelg North man was found dead.
Detectives from Western District, the Forensic Response Section and Major Crime Investigation Branch attended the scene and are treating the incident as a murder-suicide, the police stated on Wednesday afternoon.
The investigation is in its early stages and the police are working to determine the circumstances surrounding both deaths.
Both men were known to each other and resided at the address.
The deaths come on the back of a shocking spate of domestic violence murders in South Australia that occurred within the space of a week.
Last Thursday, police discovered the body of alleged wife killer Kevin Jewell near Curramulka on the Yorke Peninsula after a two-day manhunt for the 55-year-old man.
It’s thought Mr Jewell murdered his wife Jodie with a gun before running off.
Police revealed Ms Jewell had confided to a friend that she was a victim of domestic abuse and the police discovered her body after a friend became concerned for her welfare.
On November 16 in Davenport, Port Augusta, police allege Michael Amos, 53, murdered his former partner.
On November 19, police allege Morphett Vale man Clifford Neumann murdered a 39-year-old woman, who was known to Mr Neumann.
On November 21, a 50-year-old man was arrested for the alleged murder of a 44-year-old woman in the Adelaide suburb of Felixstow on November 15.
There are now growing calls for a state royal commission into domestic violence.
