Video: Police probe cold cases in Sandringham murder investigation An investigation was launched after a dog walker discovered the remains at 4pm on New Year's Day just a mile from the Royal Stud and less than two miles from the estate's main residence. Officers are carrying out a "detailed search" throughout the area of woodland in Anger, near King's Lynn, which is east of Sandringham House, where members of the Royal Family had gathered. The operation was kept secret for more than 24 hours as detectives worked to establish how the body was so close to the Royal residence. The Queen and the Duke of Edinburgh, who are currently staying on the 20,000-acre (8,000-hectare) estate for their Christmas break, were informed of the discovery on Monday night.
