'There's no justice': Mother's three-year fight for justice after siblings killed in crash

It's been a painful three-year fight for justice for Angelina Kauffman, after her two children were killed in a hit-and-run crash at Heckenberg in Sydney's south-west.

After a lengthy court process, the driver of the car that killed her children was today sentenced to a minimum of five years and six months behind bars, and will be eligible for parole in three years.

"There's no justice," Kaufmann said outside Campbelltown Courthouse. 

"My kids' lives, they mean nothing to the courts."

In September 2023, Angelina's 24-year-old daughter, Alina, was picking up her 15-year-old brother, Ernesto, from his new job at K-Mart.

As they drove home, a Mercedes driven by Johnson Kokozian, 23, crossed the wrong side of the road and collided headfirst with Alina's Toyota Yaris.

Kokozian and his passengers fled the scene, before he later filmed himself laughing and eating KFC.

A court has since found his father, Kagadour Kokozian, guilty of attempting to cover up the crime, telling police the car had been stolen. He will be sentenced in May.

Johnson Kokozian's partner, Tania Savignano, has pleaded not guilty to a charge of lying to police.

In December, passenger Cruz Davis was sentenced to 15 months of community service for lying about who was driving.

"The laws here, they look after criminals. They don't care about victims," said Kaufmann, who moved with her children from the US in 2007.

A Current Affair was with her two years ago as she gathered signatures for a petition to increase the maximum penalties for serious road crimes.

More than 20,000 people supported the petition that was presented to NSW parliament, but nothing has progressed since.

"I feel that their lives were lost so they could help other people," Kaufmann said. 

"Something has to come of this."
