Raelene Polymiadis charged with allegedly poisoning her elderly parents a year apart.

A daughter has been charged with murder after allegedly poisoning her elderly parents a year apart.

Raelene Polymiadis, 62, from Adelaide, is accused of killing her mother Brenda and father Lynton Anderson by deliberately administering lethal levels of prescription drugs. 

Ms Anderson, 94, died while being treated at Noarlunga Hospital on March 12, 2022.

Her husband Lynton, also 94, died after being found unconscious by a carer at his home at Hackham in May this year. 

Ms Polymiadis has been charged with two counts of murder and is due to face Adelaide Magistrates Court on Wednesday. 

Police will allege Ms Polymiadis’ parents died from drug overdoses after she intentionally gave them prescription medication ‘that had no reason to be in their system’.

Death notices for Mrs and Mr Anderson reveal the couple are survived by four children and their partners, seven grandchildren and nine great-grand children.

According to Ms Polymiadis’ LinkedIn page, she has worked in aged care since 2016.  

Last week, Detective Inspector Mark McEachern said concerns over Mrs Anderson’s death were first raised during a coronial investigation, which unearthed alarming toxicology results.

A similarly concerning toxicology report was returned following Mr Anderson’s death.

Det Insp McEachern said detectives had no concern with the level of care Mrs Anderson received while in hospital and had also ruled out carers being involved in Mr Anderson’s death.

Police asked to speak to anyone who had contact with the couple, particularly those with knowledge of any prescription or non-prescription medication they were taking.
