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

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

Marc-AndrGrenon, 47, was charged Thursday with the 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 attackthat took place in Quebec City in July 2000, in which the victim was left for dead but survived.

Police saidtheir investigation leads them to believe there are other victims including minors connected to Grenon.

"We know that Mr. Grenon had residences in several places in Quebec, particularly in Saguenay-Lac-Saint-Jean, in Quebec City, in Lanaudire, in the greater Montreal area, in the Montrgie and in the Eastern Townships," said SQ spokespersonBatrice Dorsainville.

Police say they are treating the cases as possibly linked to a serial offender, and theyhave released photos of the suspect over the years so that other potential victims may recognize him.

His arrest is the first made by the police's cold case squad since it was beefed up with more resources in 2018.

Grenon remains detained until his next court appearance on Nov. 21.
