Police have been scouring Coral Pea Court in Colyton to investigate the shooting of Adrian Buxton, 31, in what they believe was not a random attack.

Mr Buxton appeared to be taking the bins out when he was gunned down, while his wife and child were reportedly inside the house.

Residents on Coral Pea Court phoned triple zero to report hearing up to five gunshots ring out just after 9pm.

Mr Buxton was found lying outside the house suffering gunshot wounds, at least one to his head. Paramedics arrived but he died at the scene.

It is understood witnesses told police that two people, their faces concealed beneath hoodies and balaclavas, were seen running from the cul-de-sac immediately after the gunshots were heard.

No one had been arrested over the shooting by Saturday morning. Police have been examining CCTV footage from the victim's house.

A number of distressed family members comforted each other at the scene on Thursday night, as police established a crime scene and spoke to neighbours.

One woman who lives about 50 metres from the house where the man was shot said she arrived home on Thursday night to find police everywhere.

She said she was told to "get my kiddies inside and stay safe".

"I hope the person responsible is found soon. I live not even 50 metres away and it's scary to know someone is out there," she wrote online.

Detectives and forensic officers remained at the house on Friday morning.

A NSW Police spokeswoman said Homicide Squad detectives and police officers from the St Marys Local Area Command are still investigating the man's death.

Police have appealed for anyone with information about the shooting to contact Crime Stoppers on 1800 333 000.
