Camille Joseph Cléroux (1954 – 17 January 2021) was a Canadian serial killer who murdered two of his wives and a female neighbour between 1990 and 2010 in Ottawa. After his arrest for killing his neighbor, the deaths of his wives were investigated, with him eventually admitting to killing both. Cléroux was sentenced to life imprisonment. Murders Lise Roy Cléroux married 27-year-old Lise Roy, a divorcée with a young daughter, on 4 July 1987, and the pair would have a son later on. Their marriage was reportedly happy, but in April 1990, Roy found out that Cléroux had been molesting her 10-year-old daughter. The two engaged in a heated argument in the backyard of their Heatherington Road home, during which Cléroux picked up a rock and struck Roy in the head, killing her. He dismembered her body, wrapped up the remains in butcher paper and put them in garbage bags which he hauled to Heatherington Park. He was seen doing this by a neighbour but they thought nothing of it because Cléroux had a reputation for being somewhat eccentric.

The day after Roy's murder, neighbours noticed that Cléroux had a brand-new vegetable garden in his backyard, unaware that he had built it on top of Roy's buried remains. Cléroux would later serve prison time for sexually assaulting a child. Jean Rock Jean Rock, a troubled young woman who suffered from seizures and had frequent spats with her family, met Cléroux in June 1992 while he was working as a dishwasher at a diner. The couple's common-law marriage was unstable, with the two separating several times because of Cléroux's physically and emotionally abusive behaviour. One day in the fall of 2003, Cléroux took Rock out on a walk through a wooded area near the Walkley Rail Yard, where he beat her to death with a rock and buried her in a shallow grave. In an attempt to cover up Rock's murder, Cléroux paid a female acquaintance to write letters in Rock's name to
