The daughter of two pensioners allegedly murdered them both using her own insulin, a court has heard.
Brenda Anderson died in hospital in March last year and her husband Lynton died a year later.
Their daughter Raelene Polymiadis, 62, of Craigmore, in Adelaide, has been charged with their murders.
Prosecutors told Adelaide Magistrates Court on Wednesday that Polymiadis used her own insulin to poison her mother and then administered a fatal dose when she began to recover.
The court heard how she tried the same tactic 12 months later with her father when she tried to make his death look like a suicide, The Advertiser reports.
Michael Foundas, prosecuting, said: “Neither Mrs. nor Mr. Anderson were diabetic, neither of them were in any need of insulin, and the accused was the only member of her family who was diabetic.”
The court heard how Mr. Anderson was found unresponsive at home on April 30 with tablets of oxazepam “scattered around.”
Foundas said that a post-mortem revealed that levels of oxazepam, an anti-anxiety drug, in Mr. Anderson’s system were not high enough to kill him.
“A post-mortem examination revealed two drugs in his system – oxazepam insufficient to have caused his death, and insulin toxicity resulting in his death,” he said.
“The scattered tablets were, we allege, an attempt to make this look like a suicide when, in reality, what killed Mr. Anderson was an overdose of insulin.”
“Subsequent investigations of Mrs. Polymiadis’ phone have revealed that, the day before her father was found, she had Googled the effects of oxazepam.”
Polymiadis is yet to enter a plea to her charges.
She has been remanded in custody until another court hearing on Thursday.
