Greek Australian Kerry Giakoumis, missing under suspicious circumstances after travelling to Melbourne from Adelaide on 5 June 2020, is believed to be dead.

Police divers were sent to scour the Jackson Creek area in Diggers Rest in Melbourne’s northwest as efforts were ramped up to find his body.

The search began following new information in relation to the 29-year-old’s suspected murder.

Detective Superintendent Paul O’Halloran said police believed he was murdered in the clubhouse before his body was disposed in the Jackson Creek area after a dispute likely took place at the clubhouse.

Last seen at the Hells Angels clubhouse on Lipton Drive, Thomastown, in the early hours of 10 June, 2020, when he was expected to board a flight to return to South Australia, Detective Superintendent Paul O’Halloran said the disappearance had been a “significant” case over the last 14 months.

“We’ve created a taskforce involving specialist detectives with experience in the investigation of missing persons, murder and outlaw motorcycle gangs because we believe this gives us the best opportunity to solve this case,” Mr O’Halloran said.

“We are committed to following up every avenue of enquiry and holding those with any level of culpability in relation to Kerry’s suspected death responsible.

“Police have believed for some time that he has met with foul play and all the information we have received, particularly over the past few months, just confirms that.

“We have information that his body may potentially have been dumped in Jacksons Creek near Diggers Rest and we’ve had our Search and Rescue police, along with specialist divers, out there meticulously looking for any trace of Kerry.”

The police are appealing for anyone with information to come forward, and it is understood that Mr Giakoumis was not a patched member of the Hells Angels Outlaw Motorcycle Gang.
