Police have made fresh arrests over a car crash that killed two siblings, with detectives taking a man and woman into custody.
Alina Kauffman, 24, was picking up her brother Ernesto Salazer, 15, from work when they were struck by an allegedly stolen car at Heckenberg, in Sydney’s south-west, about 9.20pm on Friday.
The siblings were just metres away from their home when a Mercedes ploughed their vehicle into a stationary Toyota Rav 4, flipping their Toyota Echo into its side and killing them instantly.
The accused Mercedes driver Johnson Kokozian, 20, has been hit with several charges over the accident and remains in police custody.
Police will allege the young father was driving with a disqualified license when he hit the pair before running from the scene and leaving them to die.

Now, detectives have had a breakthrough on the case – with officers arresting a man who was allegedly a passenger in the Mercedes.
Footage shows the man arriving at a police station in the back of a patrol vehicle on Wednesday.
He isn’t expected to be charged over the crash, but police will allege he deliberately withheld information to protect Kokozian.
Meanwhile, Kokozian’s girlfriend was taken into custody after she showed up at Liverpool Local Court on Wednesday, where her partner’s case was briefly mentioned.
Kokozian has been charged with two counts of failing to stop and assist after vehicle impact causing death, two counts of dangerous driving occasioning death, negligent driving occasioning death, and driving a vehicle during a disqualification period.
Police believe there were three people – including the driver – in the Mercedes at the time of the crash.
However, under none of the passengers will face any charges under good Samaritan laws that stipulate only the driver of a car must stop or report a car crash.

Ms Kauffman was appalled at the actions of the passengers of the Mercedes who allegedly left her children to die.
‘They just ran and left them, like (they’re) nothing,’ Ms Kauffman told 7News.
She also criticised those who decided to take footage of the crash with their smartphones instead of helping her children, saying ‘help, do something’.
The lack of charges prompted the state’s deputy premier, Prue Car, to declare at a press conference: ‘If there are gaps in the law, we will be open to looking at that.’
Lawyer Paul McGirr hit back at any plans to expand on good Samaritan laws and enforce the public to act in a time of crisis.
‘It depends on what they know, what they saw, what mindset they’re in at the time,’ he said.
‘Making it a law that some person should do some act, that’s the grey area.’
About 150 people gathered on Sunday night to pay tribute to the brother and sister.
Mourners were seen placing cards, flowers and toys at the roadside crash site during the vigil.
Mum Ms Kauffman broke down in tears after returning to the crash site on Saturday.

She shared a harrowing tribute to her children, describing them as ‘good people’ who wanted to make a difference.
‘My babies, they took them from me, my babies,’ Ms Kauffman said.
‘My kids were going to help people, my kids wanted to make a difference in this world, my kids were good people.
‘My daughter she’s such a beautiful girl, she loves her brother and my son, he loves his sister.
‘Now my son is gone and my daughter she’s gone. My kids are gone and I have to live the rest of my life with no kids, why? I don’t understand.’
Ms Kauffman said Alina was a dedicated nursing student with a kind heart, while Ernesto was an animal lover who was working at K-mart saving for his first car.
She explained her daughter had collected her son from his new job at Kmart and the pair were nearly home when they were hit.
‘Alina called me and said ”mum I picked up my brother, we are going to get some food and then we are coming home”,’ Ms Kauffman said.
‘I said ”are you okay” and they said ”yes mummy”.’

When she didn’t hear from them in 20 minutes, Ms Kauffman and her other child tracked their location down via social media.
The distraught mother said she arrived at the scene just minutes after the crash.
Officers arrested 20-year-old Johnson Kokozian after he handed himself into Liverpool Police Station on Saturday.
Kokozian denies he was behind the wheel but was charged over the crash and refused bail at Parramatta Court on Sunday.
Kokozian allegedly filmed himself eating KFC in the hours before turning himself into police.
The Mercedes was reported stolen by Kokozian’s father after police attended his address about an hour after the crash.
Police are also on the hunt for the person who filmed the crash victims dying inside the car before sharing it to social media.
A six-second video circulated online on Sunday of the moments after the crash showing the two siblings sitting inside the wreckage.
