An Adelaide carer killed in a high-speed hit-and-run was working on an assignment on caring for grieving families as part of a nursing diploma just before she died, an SA court has heard.
Mother-of-two Lucy Paveley, 40, died at an intersection near Parafield Airport in Adelaide's north while on her way to work at an Anglicare aged care home.
Lyle Leonard Morrison, 19, was behind the wheel of a stolen four-wheel-drive which was travelling at high speed on Main North Road in August last year.
He is being sentenced in the District Court, which heard he was driving at more than 120 kilometres per hour when he hit Ms Paveley's car.
Morrison and several other teenagers were arrested and charged following the crash.
The 19-year-old pleaded guilty last September to causing death by dangerous driving but denied a manslaughter charge, which was later dropped.
In a statement read to the court, a close friend of the Paveley family, Jule Chapman, described how she went to identify her friend's body, because the victim's husband could not bear to.
"To stand over my friend's body and promise to look after her young children and her grieving husband… is just not right," she said.
"She isn't just the lady that your callous actions (killed).
"She lived her life and took nothing for granted… she was the love of her husband's life… and an amazing mother."
Ms Chapman told the court Ms Paveley had been just a month away from finishing her nursing diploma when she was killed.
"Do you know what was sitting on her computer when she died? An assignment on caring for grieving families," Ms Chapman said through tears.
"I hope you keep copies of our statements and read them everyday until you change your ways [and] teach your friends not to waste their lives on crime.
"No amount of time given to you will ever make it better — Lucy is gone forever."
Morrison showed 'casual disregard' for victim's life
Morrison's co-accused — who was behind the wheel of a second vehicle, but cannot be named due to his age — is also being sentenced for his involvement in the fatal crash.
The District Court today heard Morrison and several others had taken the two cars on a joyride through Adelaide's north early on the morning of Ms Paveley's death.
Prosecutors told the court the vehicles ran several red lights and reached speeds of more than 140 kilometres per hour.
It heard the four-wheel-drive being driven by Morrison was still travelling at between 124 and 126 kilometres per hour when it went through a red light and crashed into Ms Paveley, who had just entered the intersection on a green light.
The court heard the light had turned red well before Morrison entered the intersection, meaning he would have had "ample time" to stop the vehicle.
"A decision was made by him to run that red light no matter what," prosecutors told the court.
"A casual disregard for the life of Mrs Paveley casts a long shadow over… this matter."
Morrison and his co-accused took off after the crash, but he was arrested by police the next day.
Morrison's lawyer told the court his client had not acted with "an intention to kill".
"There was not a premeditation to deprive the victim's family of this important person in their life," he said.
The lawyer asked the court to take Morrison's young age and extremely troubled background into consideration in handing down a sentence.
The maximum sentence for someone charged with death by dangerous driving for a first time is 15 years' imprisonment.
His early guilty plea to the dangerous driving charge entitles him to a discount of up to 40 per cent on his sentence.
Morrison will also be sentenced for leaving an accident scene after causing harm, driving while disqualified and driving dangerously to escape police.
The pair will be sentenced in October.
