A woman given her first shot of heroin overdosed in the front seat of a car driven by the man who had injected her.

She was in the car as he drove his friends to a drug dealer's house to buy methamphetamines, a District Court jury was told.

Stephen John Heaton, 45, is fighting a manslaughter charge. Prosecutors claim he is guilty of criminal negligence for not seeking medical assistance for Karen Scorgie until it was too late. The 27-year old died in the front seat of Mr Heaton's car in a Scarborough carpark.

Mr Heaton met Ms Scorgie on September 30, 2010. The new friends smoked cannabisat a house in Morley, the court was told.

At 3pm Mr Heaton injected Ms Scorgie with homebake heroin and about 3.30pm he took an unconscious Ms Scorgie to his car. He took a phone call from a housemate of Ms Scorgie, who heard her "gurgling" in the background.

Mr Heaton told the concerned friend he was bringing the woman home but instead drove to a house in Cloverdale and picked up his friends Tarlee White and Simon Cattalini to take them to a drug dealer's house in Scarborough.

Defence lawyer Paul Yovich has said his client did not seek medical attention for Ms Scorgie because he believed she was "on the nod", a typical reaction to heroin.

Ms White told the court yesterday: "I noticed she didn't look right, her head was back and she was making a, I wouldn't say breathing sound, but a horrible gargling sound.

"I kept saying, 'Are you sure she's all right, Stephen?' And he kept saying, 'She's fine, leave her'."

When the car reached the destination, Ms White collected the drugs and the three friends injected themselves in the car.

Mr Cattalini told the court Mr Heaton asked if giving Ms Scorgie methamphetamine would "bring her around".

"I said, I think that's a bad idea," Mr Cattalini said.

He did not see Mr Heaton inject Ms Scorgie with methamphetamine, which was alleged by prosecutor Dave Dempster.

About 6pm Mr Heaton drove the group to a petrol station but discovered Ms Scorgie no longer had a pulse. The group drove to a carpark by Scarborough beach where Mr Heaton called an ambulance.
