The heartbroken daughter of a Vietnamese mum who was struck by her own black Mercedes out the front of their family home says her three little siblings are now 'all alone in Australia'.
Kim Anh Vu's lifeless body was lying in the driveway for two hours before she was discovered by her son Thien at 7.30am on Thursday in Pennington, north-west Adelaide.
The 21-year-old panicked and called a family friend, before a kind-hearted passer-by saw the 45-year-old single mum lying under the vehicle and called emergency services.
Ms Vu's oldest daughter Huong, 24, told Daily Mail Australia that her family are at a complete loss as to how the tragic events on Thursday morning unfolded.

'I have no idea why it happened, or how it happened,' the young woman said.
'My sisters are upset and they're sad, and they're so small, and we have no other family in Australia.'
Detectives said Ms Vu's death is not being treated as suspicious, and believe she may have left the car in gear when she got out to open the gate.
'The car might have rolled back [and hit her], but we're still investigating,' a police spokesperson told Daily Mail Australia.
Huong remembered Ms Vu as a 'great mum' who found it difficult to make friends with her limited English, and felt 'a bit lonely' in Australia.
'But she still tried to work so she could feed my siblings and give them a home.'

Huong lives in Melbourne where she works in a meat factory, like her mother did in Adelaide, but flew straight to South Australia when tragedy struck her family on Thursday.
Due to Victoria's worsening Covid crisis, Huong has to stay in a quarantine hotel for 14 days before she can see her brother Thien, and her little sisters Minh, 14,
