Katherine Hawkes, 34, was attacked after leaving her downtown Montreal workplace on the evening of September 20, 1977. A citywide power failure disrupted her usual commuter train, so she took a bus and is believed to have gotten off near Grenet Street and Henri-Bourassa Boulevard between about 6:20 and 7:00 p.m., a short distance from her Cartierville home. Sometime after leaving the bus she was assaulted in brush near the Val-Royal railway station, suffering severe head injuries and sexual assault.

Police received two late-hour calls, beginning about 10:35 p.m., from a man who identified himself as the attacker, gave locations where she might be, and left a recording of his voice. Hawkes was not found that night; her body was discovered the next evening near Val-Royal station. An autopsy found she died from the beating combined with exposure. Her shoes were found in a ditch on Grenet Street on September 23. The recorded calls became a key evidentiary lead. In 2016 the calls were rebroadcast and an anonymous letter later named a person, but no arrest or public criminal charge has been reported and the case remains unsolved.

Did anyone in the area at the time ever recognize the voice on the recording or have information about the locations mentioned?
