Family and friends have sobbed and cried out as distressing footage of the moment Lisa Coleman was hit by a car driven by her former friend were played to a Sydney court.
Debra Anne Holland used her car "as a weapon", circling Ms Coleman "like a shark" before deliberately driving it at the 49-year-old twice in Waterloo in December 2017, causing her serious injuries.
In a video capturing the moment, filmed by witnesses, the women can be heard screaming at one another before a loud noise is heard as Holland's Holden Commodore hits Ms Coleman.
It was too much for many of Ms Coleman's family and friends at Holland's sentencing hearing in the NSW District Court. "Oh God," one said in horror as another left the room, unable to watch.
Holland, who was then aged 50, maintains she has no memory of the incident. However, she told the court on Friday she feared for her life that night.
She previously pleaded guilty to dangerous driving occasioning grievous bodily harm and was charged with a string of other offences including failing to stop and assist.
Ms Coleman spent more than a month in hospital after the hit-and-run, with injuries including a brain haemorrhage, rib fractures, a fractured shoulder and facial fractures.
She died in April 2018 in unrelated circumstances.
The court heard Holland and her victim had been friends and attended the funeral of a neighbour's son earlier in the day.
After drinking at the funeral's wake, Holland became "progressively intoxicated" to the point where she was refused service, court documents reveal.
She became angry with Ms Coleman, who she was meant to be staying with and who she says left her to go and buy drugs.
"I don't want nothing to do with the f***ing ice head, if I see her I'll knock her," she said in a Facebook message to a friend.
"I'm f***en going around there now. I'm going to f***en give it to her".
Holland told the court what she had meant by the messages was that she would "knock some sense" into Ms Coleman and had intended to verbally "give it to her".
She says she has no memory of driving away from the scene and only learned of her crime the next day when she saw a news report.
"I will never drive again. I do want to say I'm deeply sorry to the friends and family of Lisa and I mean that from the bottom of my heart," she said.
"I can never have closure on this. Lisa was my friend and it's something that I have to have in my heart for the rest of my life."
The prosecution queried why, if Holland was so sorry she had never reached out through police to apologise to Ms Coleman's family and friends previously.
"Your conduct in circling around Lisa is like a shark circling," the prosecution said.
Judge John Pickering will sentence Holland on October 16.
