Case 183

The MacKenzie Family

In February 1993, a tragedy struck that would put a Western Australian town on the map for all the wrong reasons. 31-year-old single mother Karen MacKenzie and her three children, Daniel, Amara and Katrina were all sleeping peacefully when an intruder entered their home and brutally hacked the family to death with an axe. The murders devastated the community and came to be known as the Greenough Family Massacre. But who was responsible? 

Investigators considered all possibilities, including that the perpetrator could be a scorned lover, or that the murders could have been a revenge attack by a local criminal gang. But when Karen’s friend Bill Mitchell is also attacked, the truth that emerges is worse than anyone could have imagined.
