The long-term partner of a man who died in a violent incident, which reportedly involved a chainsaw, has issued a stark warning to those responsible.

Gordon Kessey, 44, was found dead in a park on East Street in Bega, on the NSW South Coast, in the early hours of Monday morning. 

A second man is fighting for life in hospital after witnesses heard yelling and screaming around 2am, followed by the revving of a chainsaw.

Taking to social media on Tuesday, Mr Kessey’s partner of more than a decade, Amanda Manton, issued an emotional tribute.

‘I’m gunna miss you Gordon. I loved with all my heart (during) 11 years of us together,’ she wrote on Facebook. 

‘Don’t worry, your death won’t be forgotten about and I know that who ever loved you like I did will make sure them dogs won’t be breathing soon.

‘They’re f***ed when they go (to) jail… Get killed, dogs.’

Sharing a clip of a brawl between Lebanese and Aboriginal inmates at a NSW prison, she warned a similar fate to her partner’s alleged attackers. 

“This is what Gordon would have done to those attackers if they hadn’t used chainsaws, knives, and other weapons to kill him because he would have fought back,” she stated.

In a different post she said: ‘Putridest dog’s couldn’t fight one-on-one, had to mob and kill with weapons… Die dogs.’

A third post said: ‘Four lads involved, killed my man to death. They think they getting away with it. Prepare to be killed.’

Earlier this week, Ms Manton told The Daily Telegraph that she was nearby when he was killed and followed police as they rushed to the scene. 

She said she broke down when she learned of Gordon’s death. 

Ms Manton said a woman approached her and said: ‘Hey sis, they’ve got your man down there with the chainsaw’.

“I approached the scene with police everywhere, thinking he (Gordon) might be in the hospital or something… but one officer told me: ‘He’s deceased, he’s been found deceased in the park.’

Ms. Manton shared that her partner had battled drug addiction and had been incarcerated but turned his life around after meeting her.

It’s understood that Mr Kessey was well known to police, who are now probing whether drugs were a motive for the deadly confrontation.

Word of the gruesome attack spread fast through the coastal town.

‘My mate gave me a call and said someone was being attacked by a chainsaw down the road,’ one man said.

Police established a crime scene at the park as an investigation was launched in partnership with homicide detectives.

Investigations are ongoing.

Anyone with information, CCTV or dashcam is urged to call Crime Stoppers.
