A local man suspected of killing two police officers near Porepunkah and seriously injuring another remains at large, heavily armed and dangerous, as hundreds of police continue the man hunt on Wednesday.

Dezi Freeman, 56, allegedly fled into the bush off his rural Rayner Track property after shooting three police officers - killing two and seriously injuring another - when they and seven other officers were executing a warrant at around 10.30am on Tuesday morning.

Victoria Police Chief Commissioner Mike Bush fronted the media on Wednesday morning to confirm as of 8:30am Freeman was still at large.

“We have not had any confirmed sightings at the moment, he knows that area better than us, that’s why we’re putting in every expert and supported by local knowledge as well,” he said.

“Don’t support this person, he’s very dangerous, he killed two police officers and injured a third, he does not deserve anyone’s assistance.

“We have a large team investigating this crime and a large team that are absolutely focused on finding this suspect.

“The hunt will continue until we find him.”

Chief Commissioner Bush assured the community every available resource was working on the situation and urged them to remain vigilant.

“We will do everything to find this heavily armed individual,” he said.

Local officers and members of the sexual offences and child investigation team attended the Rayner Track yesterday, when tragedy struck.

Chief Commissioner Bush said the seven uninjured officers were ordered to “hunker down” as they heard gunfire and awaited further resources to attend the area, not knowing where the suspect fled.

“They are as you can imagine really traumatised by this and we are doing everything to support them as well,” he said.

Chief Commissioner Bush confirmed shots were discharged by police at the suspect.

Police did not recover any firearms from the scene and believe Freeman had multiple, powerful firearms with him.

Freeman’s partner and children attended a local police station late on Tuesday and spoke with police, as Chief Commissioner Bush confirmed the incident did not involve any hostages.

“We invited his partner to a police station and we have spoken with her and we also met with children to make sure they are safe,” he said.

Chief Commissioner Bush said the force planned on sharing details of the fallen 59-year-old Detective and 35-year-old Senior Constable later Wednesday afternoon, as next of kin were being notified.

He said some of the three officers who were shot were from the local area.

“This will have an ongoing impact on that community and we want to give every support to those people, we are there for them.”

Chief Commissioner Bush planned on meeting with the third officer who was shot yesterday, who he confirmed was out of surgery but seriously injured.

Police remained at the cordoned off crime scene and the Great Alpine Road roundabout on Wednesday morning and have set out a wide search area in the nearby rugged terrain.

Chief Commissioner Bush said while the force have the best search and rescue experts in the country at the scene, the suspect was well-versed in bushcraft.

The force have released limited information about the search due to the possibility of Freeman having access to media reports.

Chief Commissioner Bush said the search continued throughout Tuesday night, as 5.6mm fell in the area and another 15-35mm of rain was forecast on Wednesday.

“It was tough going for all of our people, but they are absolutely determined and focused on finding this person, they are absolutely oblivious to those conditions with this mission,” he said.

“We are open to every scenario, we have mitigations and plans in place for every situation.”

New South Wales police remained on standby.

Chief Commissioner Bush urged anyone in the area who saw anything that aroused suspicion to call Triple Zero.
