The three human skulls found stowed in plastic bags at an abandoned house in Bertrange on 16 October are at least 50 years old, the National Health Laboratory (LNS) confirmed.
The public prosecutor's office launched an investigation into the remains, which were found by builders working on a property on Rue des Champs. When using machinery to remove a rotten wooden door, two plastic bags fell out.
The grisly discovery sparked major police deployment, including the technical teams and judicial police.
During the investigation, it was discovered that decades earlier there was a cemetery in that area. Therefore, the public prosecutor's office has decided to close the case.
