Romanian prosecutors suspect that the paintings stolen from Rotterdam’s Kunsthal gallery in the biggest Netherlands art-theft in a decade were incinerated. A Romanian museum is analyzing the ashes in Olga Dogaru’s stove; Dogaru is the mother of accused thief Radu Dogaru, and she claims that she dug up her son’s buried loot and burned it to protect him — including paintings by Picasso, Matisse, Monet and others.
