An Adelaide woman, Raelene Polymiadis, is on trial for the alleged murder of both her parents. Prosecutors allege Polymiadis intentionally administered lethal doses of insulin to her parents in two separate incidents occurring over a year apart. The court has heard evidence suggesting the insulin doses were deliberately given and caused their deaths. Polymiadis has pleaded not guilty to both counts of murder. The trial is ongoing, with the prosecution presenting its case to demonstrate intent and establish the cause of death as a result of the administered insulin. Details regarding the motive behind the alleged actions have not yet been publicly disclosed. The case is expected to continue with further evidence and testimony.
