A woman identified in court as Ms Polymiadis has gone on trial accused of murdering both of her parents. The prosecution alleges that she poisoned the couple, who died in 2022 and 2023, and that their deaths were not natural. The case is being heard before a 14-person jury.
Prosecutor Michael Fundus told the jury that Ms Polymiadis poisoned her parents to death and that she murdered them. He said it would be alleged that both the husband and wife were administered lethal doses of insulin by their daughter, framing the deaths as deliberate acts rather than the result of any illness or accident.
The court heard evidence said to point to long-standing knowledge of the substance. According to the prosecution, 16 years before her parents' deaths, Ms Polymiadis allegedly commented on the lethal effects of insulin, telling a former partner about how dangerous it could be. That earlier remark was presented as part of the case against her.
The jury was also told about her access to the drug. As a diabetic, Ms Polymiadis had easy access to the same type of insulin that was allegedly used to poison her parents. The prosecution highlighted this access as a significant element of the circumstances surrounding the two deaths.
In setting out the timeline, the court heard that Ms Polymiadis was the last family member to see her parents alive. The prosecution pointed to this as part of the sequence of events it says links her to the deaths, alongside the medical evidence about the insulin doses.
On the question of motive, the jury heard that both of Ms Polymiadis' parents did not want to go into aged care, and that it is possible this was what motivated her to commit the alleged crimes. The trial is continuing, with the jury to weigh the prosecution's allegations against the evidence presented in court.
