Experts gathered newly discovered bones found inside Vatican City on Saturday as part of an investigation into the case of Emanuela Orlandi, who disappeared in 1983 at the age of 15.

A tip-off breathed new life into the decades old case, when Orlandi's family were told her remains might be buried in the tombs of two 19th-century German princesses, which were opened on July 11 and found to be empty.

While looking for the German princesses' remains, which may have been displaced during renovations, investigators found bones under a manhole inside the nearby Teutonic college. The site was sealed until forensic experts were able to gather the evidence on Saturday. The bones will be analysed in an attempt to discover their identify.

Emanuela Orlandi, the daughter of a Holy See employee, went missing on June 22, 1983 while going to a music lesson.
