KILLER ON THE RUN: Teenager murdered in the street

An 18-year-old was shot dead in the chest and a gunman is on the loose after chaotic scenes in Sydney's south west last night.

Police and paramedics were called to Cabramatta Ave at Miller just after 11pm to find the teen lying on the road beside his silver Lexus, which had red P-plates on it, and a member of the public trying to revive him.

Ambulance crews worked on the teen, who had a single gunshot wound to his chest, but he could not be revived.

Police did not have anyone in custody over the shooting this morning.

Four cars - the Lexus, a black Toyota Corolla, white VW hatchback and a purple Nissan Tiida - were all towed away as evidence.

The man died on the road in front of Miller Park, a large family playground next to Miller Technological High School. Forensic police had this morning taped off the park and were searching for evidence.

Ahmad Elhamoui was watching television in his Cabramatta Ave home when he heard a gunshot shortly followed by an argument.

"My daughter said it sounds like a car … I said 'no no it sounds like gun shot," Mr Elhamoui said.

"I stood at my door with the lights off and noticed two people arguing after the gun shot … you couldn't hear what they were saying.

"Then there were all these cars passing by and parking to the left. I don't know what was happening, more cars came along from the other side … so they literally blocked the road.

"Then police came about 10 minutes later.

"I've got young kids over there in my house it's not really a pretty thing to explain to the kids that somebody got shot in your street."
