During World War II, the Nazis confiscated thousands of artworks owned by Jewish artists and collectors. These included works from Dutch art collector Jacques Goudstikker confiscated by the German government after his death and sold cheap to Nazi officials. Some of those paintings have been found, others are still missing.
Fast forward 80 years, and the Argentine home of former SS officer Friedrich Kadgien is put on the market by his daughters. The listing had a picture of the living room, with a painting on the wall that looked suspiciously like Portrait of a Lady by Italian artist Giuseppe Ghislandi, which had been owned by Goudstikker. It was not a famous painting, but was known to be in Kadgien’s possession in 1946. The image, and all interior photos, were removed from the real estate listing after the news got out. A police raid on the house found that the artwork was gone. One of Kadgien's daughters told a newspaper that she didn't know what painting they were talking about. It might have been a simple matter for the daughters to have claimed ignorance about the painting's provenance and repatriated it to Dutch authorities, but as it is, the story is far from over. -via Metafilter
Update: Police in Argentina put Patricia Kadgien and her husband under house arrest, and have since found and confiscated this painting and other stolen artworks.
