Victoria Police set up an information caravan on the Point Nepean foreshore last week in an effort to collect new information about the death of Mavroidis (Blacky) Karpetis in December last year.

Mr Karpetis’ body was discovered in grassland near Point Leo Road, Merricks at around 1pm on Christmas Day.

The 78 year old Brunswick East man was last seen at his family’s Tootgarook holiday house on the afternoon of Tuesday, 23 December.

Detectives from the Homicide Squad were working alongside local police to gather new information from both permanent residents and those with holiday properties in the area.

Detective Senior Sergeant Stuart Bateson said police were urging one couple in particular to come forward.

“On the morning of 23 December two people spoke to Mr Karpetis and his son-in-law about some windows they had left on the nature strip outside their property on Leonard Street,” he said.

“Those people later returned to the property that same morning and collected the windows using a trailer.

“Police are appealing for this man and woman in particular to come forward and we believe they may hold vital information for this investigation.” he added.

A mannequin wearing the same style of clothing that Mr Karpetis had on at the time of his disappearance and subsequent death was also on display.

A number of items belonging to Mr Karpetis have never been recovered, including a leather Esprit wallet, silver Tag watch, Samsung E250 mobile phone, a pair of sunglasses and a pair of shoes.

“With the right information, solving a crime like this might only be one call away,” Det S/Sgt Bateson said.

“Any information, no matter how small or insignificant you may think it is, could be crucial.

“Investigators are asking that anyone who can assist with this case come to the information caravan or contact Crime Stoppers.”

Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or visit www.crimestoppers.com.au
