Rachel Nickell, 23, who had been walking her dog, was sexually assaulted and stabbed to death in front of her two-year-old son Alexander in a small copse on Wednesday morning. Her parents, on a driving tour of Canada, are unaware of her death and radio appeals have failed to trace them. Canadian police said it was like 'looking for a needle in a haystack'.
