An investigation is underway into the death of a woman who was struck by a cyclist while out for a walk. On Aug. 2, at around 3:55 p.m., a woman in her 50s was out for a walk with her husband on a pathway north of Hidden Valley Drive N.W. when a 12-year-old on a bicycle drove into her from behind, knocking her over. Police said in a Friday release that the woman sustained serious injuries. She was transported to hospital in life-threatening condition. Police weren’t notified of the incident at the time and weren’t on scene. The woman has since succumbed to her injuries.
