A man accused of killing a mother and son in Adelaide's north-west over the weekend will front court today after being charged with murder.
A family member found Antoinette Tozer, 76, and her son, Steve Tozer, 55, dead at the home on Rosetta Street in Rosewater about 1.20pm on Saturday.
Acting Assistant Commissioner Graham Goodwin said the pair had suffered "significant injuries".
Police were called to the scene and quickly arrested a 43-year-old man of no fixed address nearby.
He was later charged with two counts of murder yesterday.
Antoinette is being remembered as a lady who loved gardening and would do anything for her friends.
Troy Seedman said he knew the pair well.
"Toni was just an absolutely wonderful lady, wouldn't hurt a fly and this is just tragic," he said.
A nearby resident described the crime as shocking.
"They are friendly and they are nice people," Shaji Kunjunju told 9News.
"This was normally a very quiet street and nothing happened on this one but when I hear this, I am very frightened to live in this area."
Goodwin said the attack was not believed to be random.
It's unclear what sparked the altercation or how he got inside, but police believe it all unfolded in the early hours of yesterday morning.
"The relationship between the suspect and the occupants of that address is unknown," he said.
"It is suspected that they were known to each other, but at this stage, we don't know what that relationship was."
Police have seized a metal pole and several other items from the property.
Premier Peter Malinauskas described the crime as "confronting.
"We're seen a couple of those recently and they shock us but we should have confidence as I do that SAPOL will do a thorough investigation of exactly what happened and why."
The 43-year-old man will appear before Port Adelaide Magistrates Court today.
