Karen Ristevski's husband accused of making comments about 'getting rid of somebody' before she was killed

Karen Ristevski's husband has been accused of making chilling comments about "a good place to get rid of somebody" before the Melbourne mother was murdered.

Ms Ristevski, 41, had been missing for almost eight months when her body was discovered between logs at Mount Macedon Regional Park, northwest of Melbourne, on February 20.

Police have confirmed Ms Ristevski's husband Borce is the main suspect in the murder, but the father has vehemently denied any involvement.

In March 2016, Mr Ristevski travelled overseas to buy clothes for the family's clothing boutique and met a man through a mutual friend.

The man, who chose to remain anonymous, caught up with Mr Ristevski twice and said his demeanour sent "shivers down his spine".

"When I first met him, I asked him if he was married and he didn't reply back to me. I found that a bit weird," the man told 7 News.

"One of the comments he threw out that I found was very, very weird was, 'this is a good place to get rid of somebody,' and it's not like something you say to someone you've just met."

The man contacted police after seeing news reports on the Melbourne mother's death.

"There was something eating me up inside saying I should report it to police," he said.

Police have confirmed they are investigating the witness' claims.
