In a post to a local Facebook group, a man claiming to be Dezi's eldest son Koah hit out at "disgusting humans" celebrating the fugitive's death online.

"This is news that I'll be grieving about while some of you disgusting humans celebrate online for ME to watch," he wrote.

"Before you have something smart to say, how about you try and experience 1 per cent of what me and my family are going through?"

"If you can't then I highly recommend keeping your nasty comments and thoughts to yourself."

Koah clarified he was "not here to defend my father's action because I know what he did was wrong".

"What I'm here about however is seeing so called "friends" and people who I thought were nice people to say some questionable things," he wrote.

"Just bear in mind that to you's my father was a cop killer, but to me that's still my father who raised me to be the man I am today.

"And for the people who know me well they know exactly what I'm talking about.

"My heart also goes out to the family's of the fallen police officer who finally have closure," he added.

Dezi Freeman was reportedly shot dead on a rural property near Walwa, on the north-east Victorian border this morning after seven months on the run.

Victoria Police confirmed a man was fatally shot at a rural address in Walwa, north-east of Porepunkah and on the border with NSW, just before 8.30am.

Victoria Police Commissioner Mike Bush would not name the man shot dead, pending official identification processes, but said he was believed to be Freeman.

He is accused of murdering Victorian police officers Neal Thompson, 59, and Vadim De Waart-Hottart, 35 and seriously injuring a third at a Porepunkah property on August 26.

Earlier this month police announced three people, including Dezi's wife and Koah's mum, Mali Freeman, would not be charged in relation into the investigation, after they were interviewed regarding obstruction of police.
