Jury told alleged murder victim may have died from 'broken heart'

Key points

• A jury has been told that an alleged murder victim may have died from a broken heart after learning she would move to a nursing home. Raelene Polymiadis, 66, is on trial in South Australia's Supreme Court, pleading not guilty to murdering her parents by injecting them with her own insulin in 2022 and 2023.
• Prosecutor Michael Foundas said she poisoned them to death.
• In her final address, defence barrister Marie Shaw KC argued the prosecution had not excluded that the couple chose to end their lives, and that Brenda Anderson may have died from heart failure.
