Police say an 18-year-old man who was shot dead outside a home in Sydney's south-west on Saturday night was the victim of a targeted attack.
Emergency services were called to Cabramatta Avenue in Miller just after 11:00pm after reports of a shooting.
An 18-year-old man, later identified as Omar Elomar, was found with a gunshot wound to his chest.
Paramedics attempted to revive the teenager, but he died at the scene.
The shooter has not been found.
Superintendent Adam Wild of Liverpool police said the shooting was not random.
"What we can assure the community here at Liverpool is that the incident is not random. It was targeted," Superintendent Wild said.
"It is a tragic crime. Any sort of firearm or violent crime is tragic. And is one of the reasons we have afforded a lot of resources to this particular matter."
Local resident Ahmad Elhamoui said he heard an argument in the street after the shooting.
"I was just watching TV at night-time and then around 11 o'clock I heard the gunfire," Mr Elhamoui said.
"There were some men just walking around. You could hear some argument but you can't hear what they are saying."
Mr Elhamoui said he has young children and many families live in the street.
"I've got young kids. It's not really a pretty thing to explain to the kids that somebody got shot in your street.
"It could happen anywhere. Anybody could get killed."
