A man whose wrapped body was found dumped near Sydney's Olympic Park has been identified as a 33-year-old Thai man who was last seen at a nearby petrol station two weeks before a truck driver made the gruesome discovery.
Wachira "Mario" Phetmang's body was found on Homebush Bay Drive by a passing truck driver who pulled over due to bad weather on the morning of June 6.
Detectives on Wednesday said Mr Phetmang was last seen at a South Hurstville service station, about 16km from Homebush, at about 7.30pm on May 25.
He was driving a silver 2004 Hyundai Terracan, with Victorian registration URK109, said police, who are working to piece together his last movements.
