The human remains were found on New Year’s Day in Anmer, part of the Sandringham House estate, by a local citizen who had gone out for a stroll, according to police.
While no official details about the body have yet been released, it may have “been there for some time,” says Detective Chief Inspector Jes Fry.
“We are at the very early stages of the investigation and it could be a complex inquiry,” he said.
An autopsy will be done today to determine the exact cause of death.
“The remains were found by a member of the public who reported the incident to police on Sunday, Jan. 1, shortly after 4 p.m.,” Norfolk Constabulary said in a prepared statement. “The area has been sealed off and a detailed search is currently being carried out.”
Buckingham Palace would not comment on the discovery, stating only that it was a matter for Norfolk police.
In keeping with tradition, the royal family spent the Christmas holiday at Sandringham.
Anmer, which is located approximately 115 miles northeast of London, is home to several dozen people and is about three miles away from Sandringham House, which has served as a private residence for British monarchs since 1862.
The Sandringham House estate employs more than 100 full-time staff members.
The disturbing discovery of the dead body comes less than one year after the body of an American man was found in a park just yards from Buckingham Palace.
Robert James Moore, who was obsessed with the royal family, sent a myriad of letters to Queen Elizabeth and camped out near the Palace.
His body was discovered in March 2011. It is believed he had been dead for almost three years.
