Investigations are continuing into the stabbing of two police officers and the fatal shooting of their attacker in an incident in South Australia's mid-north.
Sergeant Ian Todd, 53, suffered critical wounds to the neck, arms and hands and Sergeant Jordan Allely, 32, serious wounds to his right leg and arm.
Both were airlifted to the Royal Adelaide Hospital for treatment.
They were injured after going to a home in Crystal Brook on Wednesday to follow up on a minor incident at the town's supermarket the day before.
The man who lived at the Symons St property was fatally shot.
Speaking at the scene, Police Commissioner Grant Stevens did not identify the offender but said his body was found by police who responded to the first calls for assistance.
He also declined to comment on whether the man was known to police before the attack.
"This is not an indication of the type of activity we normally see in small regional communities but we really don't know what's happening beneath the surface in some situations," he said.
Mr Stevens said the two injured officers were highly regarded in their local communities.
"They're good people. They are respected. The way they do their job is also respected," he said.
"I'm sure this will be felt quite harshly by those local communities."
SA Police Association President Mark Carroll said the incident showed how quickly situations could escalate.
"Policing is a highly dangerous occupation. We try to be as safe as we possibly can," he said.
"But it's so unpredictable. People can do things in an instant."
SA Premier Peter Malinauskas said the incident "will be difficult news for the South Australian community to absorb".
"Our frontline workers do an inherently difficult and dangerous job each day when they go to work," he said.
"They exercise this duty with courage and bravery."
No South Australian police officer has been killed while on duty for more than 20 years.
