Mr. Giroux was beaten about the head and face with a heavy object by three female passengers on October 23, 1979. He was thrown into a ditch and his cab stolen. He died of his injuries two weeks later. The three Aboriginal women, aged 19, 21 and 29, had been drinking and taking drugs on the day of the murder. The ringleader was a psychiatric patient and had consumed a large quantity of tranquilizer pills. The professed motive for the killing was to avenge the death of a fellow Mohawk band member who was shot by an officer of the Sûreté du Québec a few days earlier. The police officer was charged with manslaughter in the case. Two of the women attended the viewing of the victim's body and left the funeral parlor "fired with a desire for vengeance against 'a white man'." All three women pleaded guilty to a reduced charge of manslaughter. The "initiator and most active participant" in the attack was sentenced to seven years. The other two received sentences of six and four years. The judge rejected a prosecution recommendation that the "initiator" be sentenced to ten years, citing her mental condition and the fact that she was under the influence of drugs. The judge also considered the shooting of the Mohawk band member to be a "strong element in the origin of the crime."

Nearly 400 taxi drivers attended Mr. Giroux's funeral and formed a procession that accompanied his remains to Montréal's Côte des Neiges Cemetery . (Source: René Picard photo (detail), La Presse, Saturday November 10, 1979, p. A-22, via Bibliotheèque et Archives nationales du Québec.)
