Vic Police seek help to solve Lim murder

A man whose body was wrapped in plastic and dumped nearly five years ago may have had links to a criminal drug syndicate.

The unsolved murder of Shu Jian Lim is still on the radar of Victoria Police, who on Tuesday released fresh CCTV footage .

Mr Lim's body was found dumped in Mt Cottrell on September 17, 2015, by university students conducting research at a creek in Cobbledicks Ford Reserve.

It took another month to discover the body was that of the 26-year-old, who had been reported missing by his sister in March 2015.

"This was a brutal crime," Homicide Squad Detective Inspector Tim Day told reporters on Tuesday on the renewed effort to get justice.

"Anybody who is prepared to kill somebody, wrap them in plastic and then dump them in the river has absolutely zero regard for human life."

The family has waited five long years for answers and the senior officer hopes now is the right time to give them that closure.

"There are a number of Lim's associates we have spoken to over the years and investigators are still not satisfied with their version of events," he said.

"One avenue of inquiry for investigators has been that Lim's death is possibly connected to a drug syndicate that was operating in the area at the time."

Mr Lim was last seen at a friend's house at Covent Gardens in Point Cook on February, 20, 2015, as he drove away in his silver Toyota sedan.

The car was later found in Laverton after a resident reported it as a dumped car.

Police were later told an unidentified Asian male, not believed to have been Mr Lim, was seen parking the silver Toyota with registration plates 1EB 8ZD, in the street on or around February 20.

Police have now released CCTV from a water treatment plant that shows vehicles travelling past one of the exit routes from the reserve where the body was found.

They are hopeful members of the public may be able to identify one of the vehicles.

Police have also released images of Mr Lim's car in the hope someone can provide information on its movements and who may have been driving it around the time of his death.

"We do know that Lim was in Australia on an expired visa," Detective Inspector Day said.

"So if any of his friends or associates from that time are concerned about that fact, I would like to stress that information can always be provided anonymously via Crime Stoppers."
