A blood-stained carpet is one of the only clues Minh Phuoc Nguyen left behind following his mysterious disappearance 11 months ago.
Detectives suspect Mr Nguyen – also known as Paul – has been murdered and believe his organised crime links might have something to do with it.
Mr Ngyuen was last seen driving out of the Hilton Hotel in the Sydney CBD on the night of May 1, 2014.
However, detectives received information the 50-year-old may have later visited a unit block in Bankstown.
A search of the Dudley St apartment earlier this year uncovered a large blood stain on the carpet police believe came from Mr Nguyen.
A white truck, similar to one seen at the units at the time, has also been seized for forensic examination.
Mr Nguyen was a familiar face around Bankstown and often visited the local sports club as well as Oscars Sports Hotel.
“Whilst we don’t know for certain, we believe it may be Mr Nguyen’s associations with the organised crime element that may have made him a target,” Homicide Squad Detective Inspector Jason Dickinson said on Tuesday.
Insp Dickinson wouldn’t elaborate on the links, only saying they weren’t direct.
A search of a room at the Fountainbleu Motel at Casula, in Sydney’s southwest, three days after Mr Nguyen was last seen uncovered an airline boarding pass and hire car rental agreement in his name.
Insp Dickinson said there were people in the motel room when the documents were found and they had spoken to police.
Mr Nguyen’s gold Renault Latitude hire car hasn’t been seen since last May either.
The Vietnamese migrant had only just reconnected with his three brothers and sister after becoming estranged from them when he moved to Australia in his 20s, got married and had a child.
