On 21 February, 1993, the community of Greenough, Australia, awoke to the news that there had been a brutal mass murder which became known as the Greenough Family Massacre. 31-year-old Karen MacKenzie and her three children, 16-year-old Danny, 7-year-old Amara and 5-year-old Katrina were brutally bludgeoned to death with an axe - Karen had also been raped. The perpetrator was William Patrick Mitchell, an old friend of Karen who she had recently turned down when he made advances toward her. He was sentenced to four consecutive terms of life imprisonment, with a non-parole period of 20 years. His parole was denied in 2013.
