< p class="StyledBodyHtmlParagraph-sc-48221190-4 hnvfyV">Recall that Guylaine Potvin, a 19-year-old student, was murdered in her apartment on rue Panet in Jonquière on April 28, 2000. According to the evidence presented by the Crown, Marc-André Grenon allegedly entered her home while she was sleeping, sexually assaulted her and strangled her. The autopsy report concluded that strangulation caused the victim's death.
Investigators had known for more than two decades that male DNA had been found at the crime scene and on the body of Guylaine Potvin. However, to determine who a genetic profile belongs to, there must be comparison and concordance, which proved impossible for a very long time in this case.
It was only in 2022, with the use of innovative techniques in judicial genealogy, that Marc-André Grenon attracted the attention of the police. The man, now 49 years old, was arrested in Granby in October 2022.
Analyzes showed that his DNA had been detected on a belt found in Guylaine Potvin's room, as well as on a box of condoms abandoned at the crime scene. Statistical calculations also tend to demonstrate that it was Marc-André Grenon's DNA which was found in samples taken from the victim's body.
