"An entire family was systematically purged from 2009 to 2013 in this modern-style, Mississauga home. In 2009, Bill Harrison (64) was found dead inside the bathroom of the family home. It was suspicious, but chalked up to heart irregularities. One year later, his wife Bridget was found dead at the bottom of the staircase. There were signs of a struggle and asphyxiation. Though, homicide was ruled out and the death was labeled accidental. Three years later in 2013, Bill and Bridget’s son, Caleb (40), was murdered while he slept in his bed. The scene was staged to look like robbery gone wrong. Unbelievably, it wasn’t until 2014 that the police discovered a bitter custody battle, between Caleb and his ex-wife Melissa Merritt, at the root of these evil acts. When the Harrison’s threatened to take custody of Caleb and Melissa’s children, Melissa and her common-law husband, Chris Fattore, decided to kill the Harrison family. Melissa and Chris were found guilty of murder in the case of Caleb and Bridget Harrison. While Chris faced a second degree murder charge in the case of Bill Harrison, there was insufficient evidence to convict him. "
