Wetherill Park truck crash: Driver is released without charge after single mother was killed in front of her L-plater son

A lorry driver who hit a single mother in front of her L-plater son has been released without charge pending further investigation.

Leonia Picone, 55, was teaching her 17-year-old son to drive in Ofill Park, western Sydney, around 6.30am on Wednesday when a lorry collided with her Ford Mondeo as she turned off the main road.

Footage showed Ms Picone getting out of her car and standing in front of the truck to get the driver’s attention.

The truck then accelerated and hit her in front of her son.

Paramedics tried to resuscitate her, but she died on the spot.

The driver, 51, was taken to Liverpool Hospital for mandatory drug and alcohol tests.

He was also questioned by police, but was released without charge.

“The driver has been released pending further investigation,” a NSW Police spokesman told Daily Mail Australia.

Ms Picone’s son was treated for shock but was otherwise unharmed.

“It’s absolutely appalling for the family,” said NSW Police Inspector Josh Dixon.

“The pedestrian was on the road trying to get the attention of the driver of that vehicle.”

Friends and family went to the scene on Wednesday to pay tribute to the single mother following the tragedy

A crime scene has been set up and will be investigated by specialist agents from the Crash Investigation Unit.

A report will be prepared for the coroner.
