The family were in a devastating vehicle crash on Boxing Day that also claimed the life of the driver of the other auto, Craig Anthony Whitall. Jessica was sent to St. George's Hospital, and has undergone multiple surgeries including having part of her skull and a kidney removed.
Last night, the Daily Telegraph revealed Jessica's extended family had chose to switch off her life support in the hope that she could be woken from her coma.
Her sister Annabelle, 21, was also injured and died in hospital on December 29. "Jessica is a most handsome person".
Her parents and sister's funerals took place this week in Sydney.
In a funeral notice, Lars, Vivian and Annabelle were described as a "dearly loved and cherished father, mother and sister to Jessica".
According to The Telegraph, Whitall's driving record includes four jail sentences for traffic offenses, a nine-year driving ban, and "at least 10 convictions for driving while disqualified".
The actress, who was best known for her role in Home and Away, had her life support switched off at St George Hospital on Thursday, and a relative told Daily Mail Australia: "We made sure Jess wasn't alone and her friends were able to be there with her".
'The irony of this tragedy is Lars was such a careful driver, ' Mr Ponticello said. 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. We'd always have a laugh.
"It has just been a horrific crash and everything the community expects us to do to keep them safe hasn't worked in this instance", she said. I will always miss you.
The Falkholt family requested donations to children's charity Redkite in lieu of flowers.
In the aftermath of the crash, the director of soon-to-be released Australian film Harmony, in which Falkholt has the starring role, described her as an unbelievable actress who was "on her way to stardom".
