Kristian White was sentenced to 450 hours of community service and placed under the supervision of a corrections officer for two years for manslaughter.

“Mr. White made by what any measure was a terrible mistake,” Justice Ian Harrison said in the New South Wales state Supreme Court.

Prosecutors had called for a prison term in the killing of Clare Nowland, a great-grandmother who suffered dementia, but the judge said such a punishment was disproportionate.

“It is … at the lower end of seriousness of crimes amounting to wrongful death,” Harrison said.
