The body of a murdered man was discovered in a ditch. He had been fatally shot in the head. The police determined that Mr. Tessier was a friend and business associate of the deceased. They asked him for an interview with intent to ascertain the victim’s last known movements and to establish a victimology. After voluntarily attending at a police station for an interview, Mr. Tessier took the interviewing officer to a truck to retrieve items that belonged to the deceased. Later that day, he returned to the police station and requested a second interview to provide more information. He asked the police to accompany him to his apartment to confirm his rifle was still there. At the apartment, it was determined that the rifle was missing. The police then suspected Mr. Tessier committed the murder and, for the first time, Mr. Tessier was cautioned and instructed on his right to counsel. The trial judge admitted Mr. Tessier’s statements to the police before he was cautioned into evidence. A jury convicted Mr. Tessier of first degree murder. He appealed from the conviction. The Court of Appeal set aside the conviction and ordered a new trial.
