Authorities suspect dissatisfied Rai employees may be behind the theft, which was discovered by accident in March after a painting was knocked over and its frame broke, which was revealing it to not be an original piece.

That piece, which was supposed to be a work by artist Ottone Rosai, had its disappearance traced back to a retired employee who admitted selling it off in the ‘70s. That specific crime will not be prosecuted as it falls outside the parameters of the statute of limitations.

Other valuable pieces by Monet and Modigliani disappeared completely from the collection, which had been acquired over the years with public funds. The missing pieces were identified after a survey was conducted following the fake Rosai piece being discovered.

 “These were works of great value that were just hanging on the walls of the corridors or rooms in Rai’s buildings, without any alarm system, and so anyone could just walk in and take them,” Giuseppe Scarpa, a journalist covering the investigation noted about the Rome headquarters from which many of the pieces were taken. 

The value of the missing pieces has been estimated by some to be somewhere around €20 million. Among the stolen artwork are the paintings Domenica della Buona Gente by Renato Guttuso, Vita nei Campi by Giorgio De Chirico, and Il Colosseo by Giovanni Stradone.
