Lisa Maria Trewren, accused of killing David Hoy while driving dangerously applies for bail

A disqualified driver was allegedly drunk to the point of vomiting and still downing cans of Carlton Dry when she hit and killed a pedestrian, a court has heard.

A woman accused of hitting and killing a pedestrian while driving in the Adelaide Hills was “drunk to the point of vomiting”, according to a passenger in the car, a court has heard.

Lisa Maria Trewren, 38, from Murray Bridge, on Monday appeared in the Adelaide Magistrates Court, where she applied for release on bail.

Ms Trewren is charged with aggravated causing death by dangerous driving over the crash that killed David Hoy at Totness just after 11.15pm on December 20, 2021

A police prosecutor told magistrate Michelle Sutcliffe that a male passenger in the car when it hit Mr Hoy gave an account of what happened that evening.

He said Ms Trewren initially had been sitting in the back seat of the car, while a second man drove the pair from Hahndorf to Maslins Beach.

The court heard Ms Trewren and the other man were drinking Carlton Dry cans and got into an argument as they headed to Mount Barker.

The prosecutor said the man got out of the car and Ms Trewren got into the front seat.

“(The male passenger) describes pleading with the accused not to drive because of her intoxication,” the prosecutor said.

“However she insisted that she was fine and drove off with them both in the car. He gives a description of the accused as very drunk to the point of vomiting.

“She continued to drink Carlton Dry and he says he believes she drank seven to eight beers from 5pm.”

The court heard the male passenger had described the driving as “very scary”.

“(The male passenger) states she was driving like she was drunk – at times going very slow and at others very fast,” the prosecutor said.

“He describes seeing the victim walking along the gravel footpath pushing a trolley.

“He describes seeing the car veer left towards the victim and yelling at the accused. Before he knew the car had struck the victim.”

Mr Hoy was walking along the gravel side of the road pulling a two-wheel sack truck he had used to collect cans.

He was hit by the corner of the car as it left the road and sustained critical injuries.

Ms Trewren, who police allege had been banned from driving on October 25, 2021, was initially charged with aggravated causing serious harm by dangerous driving.

Mr Hoy later died in the Royal Adelaide Hospital from his injuries and Ms Trewren’s charges were upgraded. The male passenger said he yelled at Ms Trewren to stop the car.

“He says he immediately pulled his phone out to call police and he states that she repeatedly told him not to call police and to get back in the car and they would just go,” the prosecutor said. “Another car stopped at the scene to provide assistance.”

The police prosecutor said Ms Trewren’s blood-alcohol level was 0.162 – more than three times the limit.

Ms Sutcliffe ordered a home-detention report ahead of a further hearing next week.
