Details of the crash and his charges

Mr Thorne was arrested and charged by Major Crash Investigation Section officers on Tuesday, October 29, after the three-car collision on the Riddoch Highway.

On Sunday around 2.40pm, a woman driving a black Holden sedan collided with an emu.

She was not injured in the crash.

A grey Toyota station wagon with a family from Mount Gambier in it braked to avoid a collision with the Holden sedan.

However, seconds later a white Nissan ute allegedly crashed into the back of the Toyota.

Two children in the station wagon died in the crash while other occupants were injured.

Mr Thorne was charged with two counts of causing death by dangerous driving and four counts of causing harm by dangerous driving.

He was initially refused bail before his first court appearance in the Adelaide Magistrates Court on Wednesday.

Court appearance

Mr Thorne appeared before the Adelaide Magistrates Court via video link on Wednesday – the case had to be heard by an Adelaide Magistrate as the father of the accused works as a sheriff in the Mount Gambier Courthouse.

Friends and family of Mr Thorne gathered at the Mount Gambier courthouse to watch the appearance, holding hands tightly and crying as he was granted bail.

They declined to speak to media as they left the courthouse.

Missing phone at centre of bail opposition

In court, a prosecutor told the court they were opposed to bail as Mr Thorne’s phone had not yet been recovered and data showed it travelled south after the accident before it was turned off.

The court heard the phone was not found at Mr Thorne’s home during a search so police requested his phone account details.

“Police have used those details to access the phone this morning and it has pinged at the home address once again,” the prosecutor said.

“I don’t accept that the defendant and his family are unaware of where the phone is – I am suspicious of some perversion.”

What happens next?

Magistrate Ben Sale said while he was troubled by the allegations of interference he noted that whatever interference may have occurred happened while Mr Thorne was in custody and there was no suggestion he was directing those efforts.

He also noted Mr Thorne’s youth and lack of criminal history and he was granted bail with conditions, including reporting to the police once a week.

He is scheduled to appear in court again in May 2025.
