Heckenberg car crash: Young dad accused of crashing a stolen Mercedes into another car killing brother and sister aged 15 and 24, allegedly made a Snapchat video dining on KFC before turning himself in to police

The young father accused of causing a crash that killed a brother and sister allegedly videos himself gladly eating KFC in the hours between the incident and turning himself into police. 

Alina Kauffman, 24, and her brother, Ernesto Salazer, 15, died when an allegedly stolen Mercedes crossed to the wrong side of the road to collide with their Toyota Echo in Heckenberg, in Sydney‘s southwest, at 9.20pm on Friday.  

A video emerged sometime after the crash and the early hours of the next morning showing the man who was allegedly in the Mercedes, Johnson Kokozian, 20, at KFC.

The Snapchat video shows Kokozian eating a plate of chicken, chips and gravy while telling the camera how much he was enjoying the meal.

Parramatta Bail Court heard on Sunday that numerous witnesses alleged Kokozian as the driver.

After hitting the Toyota the Mercedes skidded into a stationary Toyota RAV4 before being flipped on its side.

Johnson Kokozian, 20, allegedly told police that he was the front seat passenger in the Mercedes registered to his father 

The two RAV4 occupants of the RAV4 were unhurt.

It is alleged Mr Kokozian and two other people climbed out of the wrecked Mercedes and got into another car to drive off after making no attempt to help the siblings who were fatally wounded in the Echo.

Magistrate Rob Rabbidge said he was satisfied Kokozian was the Mercedes driver in what he called an ‘appalling situation’ as he refused bail, the Daily Telegraph reported.

The court heard police had visited Kokozian father’s house following the crash to alert him about it.

The court heard the man allegedly claimed the car had been stolen. 

Kokozian, who has a son, was supported by his girlfriend and father in court. 

Angelina Kauffman, the mother of Alina and Ernesto, said her beautiful two kids ‘did not deserve to die’.

She said Alina had just picked up Ernesto from his new job at a Kmart only 200m from their family home 

Alina called me and said “Mum, I picked up my brother, we are going to get some food and then we are coming home”,’ Angelina told the Daily Telegraph.

‘I said “are you OK?” and they said “yes mummy”.’
