One neighbor saw three people arguing on the street minutes before the trigger was pulled.

Another witness, Suhair Bdeiwe, heard a gunshot and ran to her balcony where she saw a white ute speeding away from the scene.

She said she thought the sound of the gunshot was a car crash until she saw the body in the middle of the street.

"I saw the body … in the middle on the street," she told The Herald Sun.

Morgan is a well-known figure in Australia where he was acquitted of the murder of his brother-in-law Mansour Suha, who had been charged with molesting three girls, including two young relatives.

Following his acquittal for murder in 1997, Morgan was refused reinstatement into the New South Wales Police force and instead became an auctioneer, running Morgan’s real estate agency.

Morgan told the Sydney Morning Herald he had “worked hard and built a new life” for himself.

Suha was shot at a home in Oakhurst, Western Sydney, on May 26, 1995 after being released on bail over the alleged molestation.

Morgan admittedly shot Suha six-times.

When a jury took 33 minutes to decide his actions were justified, public debate erupted in Australia over the implications of vigilante-style justice.
