Police believe the events leading up to a black car crashing into a creek in western Sydney on Thursday morning could help them understand why a man was fatally stabbed nearby.
The body of Mak Muon, aged in his 20s, was found with stab wounds at Emu Green Reserve in Emu Plains just before 8am on Thursday.
Emergency services were called, but he was pronounced dead at the scene.
Detective Inspector Jason Pietruszka said it appeared the man, who was from the Nepean area, had been dead for several hours. He was known to police.
"His interactions with police do cause concern, but they do also point us to why he may have been in the area and it is a course of the investigation we are following," Inspector Pietruszka said. "There could have been some kind of altercation that led that vehicle to end up where it did."
He said police believe the incident was targeted.
CCTV from a home filmed at 4am shows the black car driving down a residential street, with another car following closely behind.
One neighbour told Nine News she'd heard a lot of noise.
"You know, like screeching of a brake," she said.
Two men known to the deceased, who were at the scene when police arrived, are assisting with their inquiries. One of the men handed over his shoes and cash to officers.
Anyone with information is urged to contact Crime Stoppers.
