Ex-nurse denies giving elderly residents fatal insulin doses

A former nurse has denied injecting two elderly residents with fatal doses of insulin at a New South Wales aged care facility. 

Under cross-examination in the NSW Supreme Court today, Megan Haines denied injecting the residents because she knew insulin would not be detected in their bodies.

Ms Haines, 49, has pleaded not guilty to murdering Marie Darragh, 82, and Isobella Spencer, 77, in the middle of the night in May 2014.

The crown alleged at a trial last week the nurse administered a fatal dose of insulin to both elderly women at Ballina's St Andrews Village after they complained about her.

Ms Haines had been told not to go into the two women's rooms without another person present following the complaints.

She previously admitted to the jury she had been handed a document setting out the complaints hours before the women died.

But she said she was relieved when a fellow nurse told her she would probably only receive a reprimand over the issues.

The court has previously heard that both women were found unconscious in their beds and there was no sign of disturbance.
