A South Australian mother has made an emotional plea for tougher penalties for those who fail to seek help in an emergency, two years after her daughter's overdose death.
Amy Bowden's boyfriend Ethan Ross was there in her final moments but he failed to get help as the 26-year-old lay unconscious inside her Redwood Park home in Adelaide's north-east.
He has since admitted he injected Amy with meth to try to reverse a heroin overdose in February 2024.

The next day she was found dead, which was a fate her family said could have been avoided.
"Amy was a stunningly beautiful person inside and out," her mum Michelle Sposito said.
"Her death could most likely have been preventable if Ethan Ross had called Triple Zero and got real help for her."
Ross previously pleaded guilty to administering a drug, a charge Amy's family says is inadequate.
They want new laws targeting those who fail to get help during an emergency.
"In other states and territories we have specific laws to make sure perpetrators are held to greater account," Sposito said.
Facing a maximum 10 years behind bars, Ross sat silently inside the courtroom today as Bowden's family refused his apology letter.

"We don't believe it's an apology, it's just another way to get out of where he is," step-father Bryan Bowden said.
Ross, who is in custody, will be sentenced in a fortnight.
But Sposito said that won't be the end of her fight as she plans to continue to work in her daughter's name and rally the government for tougher laws.
The government said it was monitoring the case closely.
"We will never stop fighting for justice for our beautiful Amy," Sposito said.
