A Sydney man and his mother who admitted to killing Sydney police officer Bryson Anderson have been sentenced to 35 years and 10 years.
Detective Inspector Bryson Anderson, 45, was stabbed twice during a siege at a property in north-west Sydney in December 2012.
Police were called to the property, where Fiona Barbieri and her son Mitchell Barbieri lived, after a bow was used to fire arrows during a neighbourhood dispute.
