Quebec suspect in decades-old murder and sex assault may have other victims: police

Quebec provincial police say they believe a man charged this week in the murder and sexual assault of a junior college student 22 years ago may have had other victims. 

Marc-André Grenon, 47, was charged Thursday with first-degree murder and aggravated sexual assault of Guylaine Potvin, 19, in April 2000.

He was also charged with attempted murder and sexual assault in a separate, violent sexual assault that took place in Quebec City in July 2000, in which the victim was left for dead but survived.

Police said today their investigation leads them to believe there are other victims — including minors — allegedly connected to Grenon.
