Marc-André Grenon attempted to make another victim in July 2000, two months after killing Guylaine Potvin in Jonquière.
Marc-André Grenon pleaded guilty Friday morning to a charge of attempted murder for events that occurred in Quebec in July 2000. Like the murder of Guylaine Potvin, this case was unsolved until new methods of investigation Genetic analysis allows us to point the finger at the 49-year-old man.
To commit this second crime, the murderer used the same modus operandi as with Guylaine Potvin. On the night of July 3, 2000, he broke into the home of a student at Laval University. As the 20-year-old woman slept in her bed, he strangled her until she lost consciousness and left her in her bedroom, believing her to be dead.
The victim, however, regained consciousness a little later, between his bed and his wall. Her attacker’s DNA had been found under her fingernails, but no match had been found in the National DNA Data Bank until now.
This admission of guilt marks the end of the legal proceedings against Marc-André Grenon, who also gave up on appealing his case in the case of the murder of Guylaine Potvin, Friday morning.
