Quebec cold case murder trial: Prosecutors complete evidence, defence granted delay

SAGUENAY, Que. — Crown prosecutors have finished making their case against a Quebec man charged with the first-degree murder and sexual assault of 19-year-old junior college student Guylaine Potvin nearly 24 years ago.

Prosecutor Pierre-Alexandre Bernard told jurors today the Crown has completed presenting evidence in the case of Marc-André Grenon after testimony from forensic biologist Caroline Paquet.

Quebec Superior Court Justice François Huot then granted a delay to Grenon’s lawyers, who will announce Monday whether they will present a defence.

The trial has heard that officers arrested the accused in 2022 after a research tool used by the province’s forensics lab suggested the previously unidentified DNA from the crime scene might be connected to the last name Grenon.
