What Senior Constable Kristian White allegedly said before Tasering 95yo Clare Nowland

Police believe an exasperated police officer uttered three fateful words before firing a Taser at 95-year-old Cooma aged care resident Clare Nowland.

The police officer charged with assaulting a 95-year-old great-grandmother allegedly said “No, bugger it” before Tasering her.

Clare Nowland’s grieving family said she died on Wednesday after she was Tasered and knocked unconscious at her aged care facility in Cooma last week.

A police investigation considered the sequence of events that led to Senior Constable Kristian White, 33, being charged with recklessly causing grievous bodily harm, assault occasioning actual bodily harm and common assault.

It is understood the female acting sergeant who was with him will not be charged, but may face disciplinary action for possibly failing to de-escalate the situation.

Staff at the Yallambee Lodge aged care facility in the Snowy Mountains had called emergency services for assistance after dementia sufferer Ms Nowland had been holding a steak knife in the early hours of Wednesday, May 17.

Ambulance officers also attended the scene and were attempting to persuade Ms Nowland to hand over the knife when she slowly got to her feet. Senior Constable White put on slash-proof gloves.

The popular great-grandmother, who weighed just 43kg, used her walker to approach the officers with the knife in her right hand.

The female officer is understood to have said: “I can take it (the knife) off her.”

Sen Const White then allegedly sparked the Taser in warning as Ms Nowland raised her right hand with the knife still in it.

Police believe that, exasperated, Sen Const White then allegedly said “No, bugger it,” and fired the Taser, shocking Ms Nowland, who fell backwards, hitting her head and fracturing her skull.

The officer then said: “Got her, grab it.”

Police bodycam footage of the incident has been analysed by investigators who made the decision to charge Senior Constable White on Wednesday. He has been suspended on full pay ahead of his appearance at Cooma Local Court on July 5.

Police Commissioner Karen Webb initially said she would not view the footage until the full evidence had been presented to her to ensure a “proper investigation is not prejudiced”.

She said the bodycam footage of the incident was just one part of the investigation into the incident including witnesses and expert testimony.

“I’m confident that we have come to a position now, seven days later, that this matter is before the court without interference,” Ms Webb said after the charges were laid

She said the incident had also been difficult for NSW police officers.

“Of course this has been traumatic for everyone in the police force, and this is one matter while the rest of the police force continues to do their job 24/7 to protect and look after the citizens in NSW,” she said.
