VATICAN CITY -- The mystery of the 1983 disappearance of the 15-year-old daughter of a Vatican employee took yet another twist Saturday following excavations this week at a Vatican City cemetery: The Vatican said it had discovered two sets of bones under a stone manhole that will be formally opened next week.
The Vatican on Thursday had pried open the tombs of two 19th-century German princesses in the cemetery of the Pontifical Teutonic College in hopes of finding the remains of Emanuela Orlandi, after her family received a tip she might be buried there.
Those hopes were dashed when the tombs turned out to be completely empty, creating yet another mystery about where the dead princesses were.
The Vatican noted at the time that structural work had been carried out on both the college building and cemetery near St. Peter's Basilica in the 1800s and more recently, and that further investigation would be done.
On Saturday, Vatican spokesman Alessandro Gisotti said those investigations had centered on the areas adjoining the tombs and had "identified two ossuaries, located under the pavement of an area inside the Pontifical Teutonic College, covered by a manhole."
He said the area was immediately sealed off and would be opened in the presence of forensic experts July 20.
Gisotti added that the bones were located in two holes carved out of a large stone that was covered by an old pavement stone a few yards behind the princesses' tomb. That area is now technically part of the building of the Teutonic College, after expansion work on the building encroached onto the cemetery field.
The last recorded structural work done on the Teutonic College and cemetery was in the 1960s and 1970s. Orlandi disappeared in 1983.
She vanished after leaving her family's Vatican City apartment to go to a music lesson in Rome. Her father was a lay employee of the Holy See.
Her case has been one of the enduring mysteries of the Vatican, kept alive by the Italian media and a quest by her brother to find answers and closure. Over the years, her disappearance has been linked to everything from the plot to kill St. John Paul II to the financial scandal of the Vatican bank and Rome's criminal underworld.
The last major twist in the case came in 2012, when forensic police exhumed the body of a reputed mobster from the crypt of a Roman basilica in hopes of finding Orlandi's remains as well. The search turned up no link.
Last year, bones were found underneath the Vatican's embassy to Italy in Rome. Italian media immediately speculated the remains could belong to Orlandi or another girl who went missing at around the same time. But forensic tests showed the bones long predated their disappearances.
