The inquest is trying to find out if Ethan killed his mother before putting her in the driver's seat to make it look like she was driving.

The crash happened on Langhorne Creek Road, about 60 km south-east of Adelaide, on December 3, 2022.

The court is trying to find out if Mr Grosvenor killed his mother and if there were any safety issues that were not addressed.

Mr Grosvenor took his own life 11 days after the crash.

The court heard that Mrs Grosvenor's body was moved after the crash, and DNA evidence showed that Mr Grosvenor was driving.

Mrs Grosvenor's lower legs and body were in the driver's seat, but her upper body was in the passenger seat.

The police thought that Mrs Grosvenor's injuries did not match the crash if she was driving.

DNA evidence showed that Mr Grosvenor was driving and that he moved his mother's body after the crash.

Tracee Ann Grosvenor died in December 2022.

A witness saw the car pulled over on the side of the road, and Mrs Grosvenor was in the passenger seat, looking upset.

Mr Grosvenor had minor injuries and was taken into care under the Mental Health Act.

The act allows doctors to treat and detain people with mental health issues.

The son died days after the crash.

Mr Grosvenor took his own life on December 14, 2022, after leaving a hospital appointment.

He was supervised by his therapist, Rachael Rolla, because he might try to leave.

Naomi Kereru will give her findings later.

Ms Rolla said that Mr Grosvenor asked to go to the toilet and never came back.

There was no rule about what to do if someone asked to go to the toilet.

Ms Rolla knew that Mr Grosvenor had gone missing from the hospital before while being supervised.

The court asked Ms Rolla if she thought about following Mr Grosvenor to the toilet.

Ms Rolla said she did not think it was right to follow a man to the toilet.

The hospital has changed its rules since Mr Grosvenor's death.

Julie Chapman hopes the inquest will help get justice.

Mrs Grosvenor's sister, Julie Chapman, said the system failed them.

Ms Chapman said that Mr Grosvenor had mental health issues and was violent towards his mother.

She thinks that mental health services should have done more to help.
