Newlyweds Roki and Sasha Strbac yesterday said the killing of Comanchero bikie Faalau Pisu, while he attended their wedding, had ruined their night and destroyed their honeymoon plans.

The couple had only just been clapped and cheered out of the Serbian National Defence Council function centre in the south-west Sydney suburb of Canley Vale early on Monday morning when a gunman opened fire from the street and struck three guests.

Mr Pisu, 23, died a few hours later in hospital, from two bullet wounds to the head. Two men, 27 and 25, were seriously injured.

"We are so angry. That was supposed to be our wedding - a happy time - and now look," Mrs Strbac said.

She said she had no idea why anyone would target their wedding or guests but said it had taken its toll on them and their families.

"I'm too scared to go down the street in case someone recognises me," she said.

The couple have delayed their honeymoon to Thailand because of the stress and shock.

But Mrs Strbac said she and her husband would not be speaking to police investigating the murder.

"We don't want anything more to do with it," Mrs Strbac said.

Gangs Squad detectives continued to track down and interview some of the 300 wedding guests, many of whom were Comanchero members, hoping to find a motive for the shootings.

They said guests' connections to the Comanchero gang were behind the fatal hit but that it was not known whether Mr Pisu was a target.

Gangs Squad boss Superintendent Arthur Katsogiannis said police had monitored the event earlier in the night, knowing a lot of bikie members were congregating in the area, possibly raising tensions with rival gangs.

But police left when there did not seem to be any trouble.

The gunman, believed to have been travelling in a blue utility and wearing a balaclava, opened fire about 12.20am.

At Mr Pisu's family's home, near Liverpool, grieving relatives, who said they had no idea he was involved with the Comancheros let alone that he was an active member of its Milperra chapter, spent the day performing Samoan religious ceremonies.

"We already miss him more than you can imagine. This is so unfair, so sad," his girlfriend Linda Hinton said.

An autopsy was due to be carried out yesterday and Ms Hinton said funeral arrangements would be made later this week.
