Crime Investigation Australia - Season 1 Episode 12
The Greenough Family Massacre

The small hamlet of Greenough, near Geraldton, in Western Australia, some 400 kilometres north of Perth, will forever be associated with one the most horrific murders in Australian criminal history. In 1993, Karen MacKenzie and her three small children were violently murdered at their isolated house. The brutal and random nature of the attack was eerily similar to "In Cold Blood", Truman Capotes world-famous study of a family murder in an isolated house in America.When the Greenough killer was finally tracked down, charged and convicted, much of the evidence was too horrific to be made public.
