On Monday, a woman appeared in Port Augusta Magistrates court charged with the murder of Quorn man Nathan Freer.
Adriana Tennant, 48, made no application for bail during the hearing where she sat silently in handcuffs.
She was remanded in custody until her court date on February 21.
The 38-year-old father-of-two was allegedly run down by the accused with a white 4WD at about 8pm on Friday night – it is understood his young children were at the scene.
Ms Tennant is said to have struck Mr Freer with the vehicle following a verbal altercation between the two parties and another man.
Emergency services, police and a local doctor attempted to revive Mr Freer, however he died at the scene.
Far North Local Service Area Superintendent Paul Roberts said the tragedy is something the children will “carry for the rest of their lives”.
“In any small community a death is a polarising event, especially when all parties are known,” Superintendent Roberts said.
“I believe the effort and the response from all of those involved was exemplary and everyone did their best to provide a better outcome than we are faced with today. It’s a tragedy that we lost someone in these circumstances.”
Horrified friends took to social media to express their shock.
Ben Swan posted a Facebook status honouring the memory of Mr Freer, “RIP Nathan Freer, you were always a great guy, always genuine and always my good friend, quiet, kept to yourself and never hurt a fly...”
