The heartbroken families of Melbourne's fatal Love Machine nightclub shooting victims say the killers acted with inhumanity, violence and "not a care" about who they hit.
Relatives of security guard Aaron Khalid Osmani, 37, and Richard Arow, 28, spoke on Wednesday after a new clue emerged over the shooting outside the Prahran nightclub on April 14.
The shots, which also injured four others, were fired from a stolen black Porsche SUV, later found burnt out at Wollert.
New CCTV footage shows a maroon Ford ute with a silver tray, and distinctive bar across the back, seen leaving the area after the Porsche was torched.
Police are now pleading for anyone who recognises the ute to contact them.
Rebekah Spinks was about five metres from her boyfriend, Richard Arow, when he was shot dead.
She described him as the "strongest man with the softest heart".
"What this has done to the family is actually so catastrophic and it doesn't get any better every day," she said.
"These men were just so callous.
"They just had no regard for humanity at all, because not just Richard and Aaron and the people who were injured, but everyone, including me on the street, was a target that day, they didn't care who they were hurting.
"They took the the life of a really great man but they destroyed the life of hundreds of people and families that are affected by it."
Mr Arow's sister Achol Arow, said the family had not come to terms with his death.
"Every day we think he's going to walk through the door with a big smile but that's not it. It's really hard," she said.
Yom Ayom said her son Richard's death was senseless and unbearable.
The mother-of-five arrived in Australia to escape violence in Sudan, when he was 12.
She said he had promised to repay her for bringing the family here to build a better life, only for his life to be taken by the very thing she fled.
"You've not only taken his life, you've also taken mine because I don't think I'll ever recover from this," she said, through a translator.
Detective Acting Inspector Julian Horan said the shooting, in one of Melbourne's busiest entertainment precincts, was "incredibly reckless and absolutely cowardly".
"Innocent people have lost their lives as a result of someone's decision to fire indiscriminately into a crowd of people," he said.
Security guard Aaron Osmani's family said he was "very loving and caring", with his whole life ahead of him.
"It's been two months since we lost Aaron but our family is still grieving a lot, especially our parents," they said in a statement.
The family said Mr Osmani looked out for his younger brothers and sister and three-year old niece, who he doted on.
"He lived with our parents and dedicated a lot of time to caring for them. He worked on the weekends but through the week he looked after our mum and dad," they said.
"Family was so important to him and we really miss him a lot."
Investigators are exploring whether the shooting was a revenge attack on the nightclub after patrons were ejected.
