Child car seats and a double pram could be the key to finding the remains of a man who disappeared in Victoria's east more than four years ago.
Lakes Entrance resident Dalibor 'Dale' Pantic, 38, was last seen at a farm at Perry Bridge near Sale on the night of April 10, 2019.
His body has never been found but a 33-year-old Sale man was charged with his murder in November 2021.
The man has since pleaded guilty to a charge of manslaughter.
Detectives last week searched the Avon and Thomson rivers near Sale in the hope of finding Mr Pantic's body.
It is believed items from his Ford sedan were thrown into one of the rivers from a Myrtlebank Road bridge the day after his disappearance.
The items include three children's car seats and a double pram, which likely floated downstream and have been recovered somewhere in the water system.
Detective Inspector Dave Dunstan said anyone who located any of the items should contact police.
"If you do know something or might have seen or found the car seats or the pram in the river, then I urge you to come forward," he said.
"Hopefully we can continue to fill in all the pieces of this puzzle until we get the result and answers Dale's family deserve.
"Our investigators are as committed as ever and we will continue to follow up all avenues of enquiry in locating Dale."
