Karen Ristevski drive re-enactment to ‘jog memory’ of witnesses, expert says

Police hope re-enacting what might have been Karen Ristevski's last journey will jog the memory of potential witnesses, experts say, after investigators drove her car to the site where her body was found.

Ms Ristevski disappeared from Melbourne's northwest on June 29 last year.

Her husband Borce, who has denied being involved in her death but remains a suspect, said she had left their Avondale Heights house that day to go for a walk to clear her head after they had an argument about money.

She was missing for months before her body was discovered in the Macedon area in central Victoria on February 20.

Today, police drove Ms Ristevski's own car from that Avondale Heights home toward the spot where her body was dumped.

Former homicide detective Rowland Legg said the tactic would hopefully jog the minds of potential witnesses.

"Another issue may be to establish whether that vehicle could move into the area where the body was disposed of, whether the terrain would suit that vehicle," he said.

The small town of Digger's Rest was part of the police route, after CCTV captured footage of a car that appeared to be the same model as Ms Ristevski's black Mercedes driving through on the morning she vanished.

Mr Ristevski had previously told police he had taken his wife's car out for a drive along the Calder Freeway on June 29, the day she vanished, before doing a u-turn and returning home.
