Nazi looted art

In 2025 a real estate agent published an image online of the interior of a house in Mar del Plata, Argentina depicting the painting "Portrait of a Lady (Contessa Colleoni)" by Giacomo Ceruti. That portrait once belonged to the Jewish-Dutch art dealer Jacques Goudstikker until WW II and is considered Nazi looted art. The house subsequently searched by the police belongs to one of Kadgien's daughters. The painting was not found. Searches of family properties during the investigation resulted in the seizure of two other paintings and a series of engravings and drawings that may have also been stolen pieces, at the home of Ms Kadgien's sister Alicia. On 3 September 2025, prosecutors announced the painting had been returned by the lawyer of Patricia Kadgien.
