Jessica's dad Lars, 69, and mum Vivian, 60, died at the scene of the vehicle crash, as did the driver of the other auto, Craig Anthony Whitall, 50.
The life support of Home & Away star Jessica Falkholt has been switched off two weeks after her family was involved in a horrific Boxing Day auto crash which also claimed the lives of her parents and sister.
Annabelle died as a result of her injuries last Tuesday and on Thursday The Daily Telegraph reported Falkholt's life support had been turned off.
Her younger sister, 21-year-old Annabelle, passed away in hospital soon after.
Jessica (29) had remained in a coma, despite undergoing surgery several times.
Jessica's parents and sister were buried yesterday - January 11 - with their funeral taking place at St Mary's Catholic Church at Concord in Sydney's west. No decision is made without Jessica's wants in mind.
The family is now playing a "waiting game" on the condition of the actress, with doctors telling them it could be weeks or months before her recovery time is known. He also spoke of his anger and confusion over his family members' tragic ends, saying that "their lives on this earth ending on a highway makes absolutely no sense".
News.com.au report that Mr. Ponticello told the service: "The irony of the tragedy is that Lars was such a careful driver".
'Whenever asking how long it would take to drive somewhere I would suggest an average for a normal driver and then add some additional time for the Lars factor. You will always be remembered and in our hearts forever.
Whitall also lost his life in the crash. Local reports have described Whitall as a "serial traffic offender" who was driving home from a methadone clinic when his auto collided with the Falkholt vehicle.
