A couple whose bodies were found wrapped in sheets almost a year apart were allegedly lured to a western Sydney home and beaten to death over a drug dispute, say police.
The body of Son Thanh Nguyen, 39, was discovered in Bankstown in April 2013, while the body of his girlfriend Thi Kim Lien Do, 35, was found in bushland in West Hoxton in January 2014.
A passerby found Nguyen's body in a Bankstown street gutter, wrapped in a bed sheet and with his hands bound behind his back.
A 25-year-old man was arrested yesterday in Merrylands West and charged with two counts of murder, with police expecting to make more arrests.
Police says the pair was last seen together on April 10, 2013, was ambushed by an attacker, who bound and bashed them to death at a Canley Vale home.
Detective Superintendent Mick Willing told reporters in Sydney today that Nguyen was believed to have been methamphetamine cook, but could not confirm Do's involvement.
"She well may have been in the wrong place at the wrong time, but certainly our information is that Nguyen was involved in a dispute with a group which has led to his death over drugs," Willing said.
He said police were also looking into links to other investigations, with more arrests expected.
"We will be making further arrests, I can confirm that straight away," he said.
Willing said police were led to the site of Do's body over the course of their investigation into Nguyen's death.
The 25-year-old accused faces two counts of murder.
