Kristian White, who unlawfully killed a 95-year-old woman by shooting her with a taser in an aged care home last year, has been suspended from the NSW Police Force without pay.

A jury has been told how three crucial minutes became the difference between life and death for a 95-year-old woman who was fatally tasered by a police officer.

Senior Constable Kristian James Samuel White discharged his stun gun at Clare Nowland in a treatment room at Yallambee Lodge aged-care home in the southern NSW town of Cooma during the early hours of May 17, 2023.
