A $100,000 debt is believed to be at the centre of a fatal shootout involving up to five guns outside a smash repairer business in south-western Sydney.
As investigators continue to piece together who the main players were in the weekend shooting at Condell Park, it can be revealed police have been told between four to five firearms were present during the gunfight.
Safwan Charbaji, 32, was shot in the head and chest after a confrontation on Ilma Street on Saturday afternoon.
Also injured in the gunfire was Abdullah El Masri, 35, who was shot in the face.
He remains in Liverpool Hospital in a serious condition.
Mr Charbaji, who police found bloodied in the front passenger seat of a car outside Bankstown Hospital's emergency department, died from his injuries.
Fairfax Media understands an outstanding debt of about $100,000 is one theory being investigated as the catalyst for the violence.
Gunfire erupted on the street outside the A Team Body Works business after about half an hour of heated argument between two groups of people.
Convicted criminal Walid "Wally" Ahmad is linked to the smash repairs business. He was jailed in 2005 after shooting dead Mayez Danny at a Greenacre wrecking yard in 2002.
Fairfax Media also understands detectives are looking for any bikie links to those involved after a high-ranking member of the Nomads OMCG turned up to see Mr El Masri in hospital.
As detectives continued to roll out search warrants around the south western suburbs on Wednesday, relatives of Mr Charbaji gathered at Lakemba Mosque for his funeral.
It is understood police have searched the homes of people subject to firearm prohibition orders, which ban a person from owning a gun and allow police to search their homes without a warrant.
Among the properties searched since the weekend was that of Mohamad Abul Hamid Elmir, who has been charged with concealing a serious indictable offence.
Police allege Elmir and friend Adam Sam Abboud, who were in the car that drove Mr Charbaji to hospital, were not telling them the full story of how Mr Charbaji ended up with gunshot wounds.
Mohammed Alameddine, 26, told police he drove Mr El Masri to Bankstown Hospital after getting a call to come down to Condell Park.
He was also charged with concealing a serious offence after turning up to Bankstown Police Station on Monday night to get his car, which was left at the hospital.
