As accused serial killer Camille Cleroux pleaded guilty to three murder charges Tuesday, the victim’s family members sat and listened.

Cleroux, a 58-year-old Ottawa man, has pleaded guilty to one count of first-degree murder and two counts of second-degree murder.

These murders happened over a 20-year period.

In 2010, he was charged in the death of former neighbour Paula Leclair. The 64-year-old’s body was found in a wooded area near her home June of that year.

She and Cleroux lived in the same apartment building.

Today, the court heard he killed her “in cold blood” after she refused to let him move in. According to the Crown, he wanted her apartment.

He was also charged in the deaths of his ex-wife Lisa Roy and his second wife Jean Rock. Roy disappeared in 1990, while Rock went missing in 2003.

Court proceedings were delayed last fall after remains were found at Cleroux’s former home on Heatherington Rd. in south Ottawa. The remains have been identified as those of Cleroux’s first wife Lise Roy.

Cleroux has been sentenced to what amounts to life in prison. He has no chance of parole for 25 years.
