DETECTIVES are appealing for information about the last movements of Wachira 'Mario' Phetmang whose body was discovered on the side of the road at Sydney Olympic Park earlier this month.
About 10.30pm on Wednesday, June 6, police were called to Homebush Bay Drive, Sydney Olympic Park, after the body of a man was discovered on the side of the road by a passing truck driver.
The body was wrapped in a plastic material and covered with a mattress protector.
The 33-year-old Thai National had been living in Australia for the last 10 years, and most recently living at Hurstville.
A post mortem examination revealed he had been seriously assaulted, and his cause of death was blunt-force trauma.
Detectives from the State Crime Command's Homicide Squad and Auburn Police Area Command, established Strike Force Sinder to investigate the circumstances of Mario's murder.
Their inquiries have revealed Mario had been in the Sydney CBD and the Guildford area during the day on Thursday, May 24, with his last known sighting at a service station at South Hurstville about 7.30pm on Friday, May 25.
Homicide Squad Commander, Detective Superintendent Scott Cook, said detectives had released CCTV of Mario arriving at the service station, which he believed may refresh someone's memory.
"Strike Force Sinder investigators are continuing to piece together Mario's final movements and would like to speak to anyone who may have seen him that Friday night," Det Supt Cook said.
"Mario travelled to and from the service station in a silver 2004 Hyundai Terracan, with Victorian registration URK109, which we have not yet located."
Police are urging anyone with information, to call Crime Stoppers on 1800 333 000 or at nsw.crimestoppers.com.au.
