Emergency services were called to a property on Cowies Road about 12:30pm on Saturday, where police allege O'Ryan first assaulted his brother during an argument, then turned on his parents.
Two male victims, aged 76 and 47, were airlifted to The Alfred hospital with life-threatening injuries. A 74-year-old woman was taken to hospital with critical injuries. Detective Senior Sergeant Rod Findlay described the injuries as “very, very extreme … a lot of injuries requiring really serious treatment by the ambulance, and then they’ve been flown for immediate surgery”.
Police believe the weapon used was a blunt axe or tomahawk, though this has not been confirmed. “At this stage we definitely believe he’s still likely armed with that axe,” Senior Sergeant Findlay said.
O'Ryan fled the address on foot and remains at large. Police said he is of no fixed address and is known to take refuge in abandoned properties or outhouses in the Morwell area. He was last seen wearing a distinctive black-and-mustard-coloured jacket, and is described as being of medium build with dark grey hair.
A search involving police on the ground and a helicopter is underway. “The community will notice a lot of police in the Tyers and Morwell area today,” Senior Sergeant Findlay said. “You’ll see the helicopter overhead, no doubt — we are working furiously to try to bring him into custody.”
Police have warned members of the public not to approach O'Ryan if they see him. Anyone with information is urged to call Triple Zero (000) immediately, or contact Crime Stoppers on 1800 333 000.
