Now a man, who has chosen to remain anonymous, has revealed chilling comments Borse Ristevski said to him in the months leading up to his wife's murder.
In a 7 News exclusive, a man claims he first met Mr Ristevksi through a mutual friend in South East Asia in March last year.
“The first time I met him… he sent shivers down my spine,” the man said.
“I asked him a few questions… if he was married and that, he didn’t reply back to me. I found that a bit weird.”
But it was another comment Mr Ristevski allegedly made that prompted the man go to police when he heard news of Karen Ristevski’s death.
“This is a good place to get rid of somebody,” Mr Ristevski allegedly said while the pair were catching up over a few drinks.
“It’s not like something you say to someone you’ve just met. There was something eating me up inside saying I should report it to police.”
Police have confirmed they are investigating the man’s claims.
