New South Wales Police are appealing for information related to Thai national Wachira ‘Mario’ Phetmang whose body was found on the side of the road at Sydney Olympic Park on 6 June, 2018.

Detective Superintendent Scott Cook, Homicide Squad Commander, said detectives have released CCTV footage of Mario entering a service station in the hopes that it may help refresh someone’s memory and further the investigation.

According to police, 33-year-old Mario had been living in Australia for the last 10 years, most recently in Hurstville.

Mario had been in the Sydney CBD and the Guildford area during the day on Thursday 24 May 2018; his last known sighting was at the service station pictured in South Hurstville at around 7:30 p.m. on Friday, May 25, 2018.

His body was discovered on the side on the road at Homebush Bay Drive, Sydney Olympic Park, by a passing truck driver at around 10:30 p.m. on June 6.

Mario’s body was wrapped in a plastic material and covered with a mattress protector, police said in a statement. A post-mortem examination revealed he had been assaulted, and the cause of death was determined as “blunt force trauma.”

“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,” 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.

“At this stage, we do not know where Mario went after leaving the service station, and we are appealing for information about his movements from then until his body was located almost two weeks later,” Cook said, according to the police statement.

Cook is appealing to motorists who have dash camera footage and travelled in the Sydney Olympic Park area around the time of the incident to “double check their vision for anything that may assist with our inquiries.”
