Alleged art thief's mother may have torched Picasso, Monet

It may be a case of art to ashes and scientists are trying to get to the bottom of the mystery.

A Romanian museum official said Wednesday that ash from the oven belonging to a woman whose son is charged with stealing seven multi-million-dollar paintings including a Matisse, a Picasso and a Monet contains paint, canvas and nails.

The finding is evidence that Olga Dogaru may have been telling the truth when she claimed to have burned the paintings, which were taken from a Dutch museum last year in a daring daylight heist.

'A crime against humanity to destroy universal art' Ernest Oberlander-Tarnoveanu, museum director

Ernest Oberlander-Tarnoveanu, director of Romania's National History Museum, told The Associated Press that museum forensic specialists had found "small fragments of painting primer, the remains of canvas, the remains of paint" and copper and steel nails, some of which pre-dated the 20th century.

"We discovered a series of substances which are specific to paintings and pictures," he said, including lead, zinc and azurite.

He refused to say definitively that the ashes were those of seven paintings stolen from Rotterdam's Kunsthal gallery last year, because he said it was not his position to do so. He said justice officials would make that decision.

He did venture, however, that if the remains were those of the paintings, it was "a crime against humanity to destroy universal art."

"I can't believe in 2013 that we come across such acts," he said.

Oberlander-Tarnoveanu said forensic specialists at the museum have been analyzing ashes from Dogaru's stove since March, and will hand their results to prosecutors next week.

The seven paintings were stolen last October in the biggest art heist to hit the Netherlands for more than a decade. Thieves broke in through a rear emergency exit of the gallery, grabbed the paintings off the wall and fled, all within two minutes.The stolen works have an estimated value of tens of millions of dollars if they were sold at auction.

Missing masterworks

The stolen artworks include Pablo Picasso's 1971 Harlequin Head; Claude Monet's 1901 Waterloo Bridge, London and Charing Cross Bridge, London; Henri Matisse's 1919 Reading Girl in White and Yellow; Paul Gauguin's 1898 Girl in Front of Open Window; Meyer de Haan's Self-Portrait of around 1890; and Lucian Freud's 2002 work Woman with Eyes Closed.

Three Romanian suspects were arrested in January, but the paintings have not been found.Romanian prosecutors say Olga Dogaru whose son is the alleged heist ringleader claims she buried the art in an abandoned house and then in a cemetery in the village of Caracliu. She said she later dug the paintings up and burned them in February after police began searching the village for the stolen works.

Prosecutors have not said whether they believe her account, but Pavel Susara, a Romanian art critic, said the story has the ring of truth."Olga Dogaru describes how she made the fire, put wood on it and burned the paintings, like she was burning a pair of slippers," he said.

"She's either a repressed writer or she is describing exactly what she did."

The Scream stolen in 2004, found 2 years later

Art market experts said the Rotterdam thieves may have discovered what many art thieves have before them -- that easily identifiable paintings by famous artists are extremely difficult to sell at anything like their auction value."Criminals who are successful in their usual endeavors are often undone by a foray into art theft," said Robert Korzinek, a fine art underwriter at insurer Hiscox.

"They steal these works of art ... and then they have the problem that they can't dispose of them."That means many works suffer ignominious fates. Some are lost forever. Others turn up after years of being buried or stashed in storage. Edvard Munch's The Scream, stolen from an Oslo museum in 2004, was recovered in 2006, water damaged and torn. Police have never offered details on the painting's whereabouts during those two years.

Chris Marinello of the Art Loss Register, which specializes in tracking down stolen artworks, said that if Olga Dogaru is telling the truth, "this isn't the first time the mothers of art thieves have come to the rescue of their son."

One famous case involved a prolific French criminal named Stephane Breitwieser, who stole more than 200 works from small museums across Europe in the late 1990s.

His mother admitted destroying dozens of the works after police began investigating her son, cutting up paintings, stuffing the remnants down her garbage disposal and throwing valuable jewels and other antiquities into a canal.She was arrested after some of them resurfaced.

"Old Masters were washing up on the bank," Marinello said.

More than 100 works were recovered from the mud and restored, but much of what Breitwieser stole was lost forever. Mariette Maaskant, spokeswoman for Rotterdam's Kunsthal, said Olga Dogaru's allegation "underscores the pointlessness of the theft."

"If this terrible news is true, then the last trace of hope that the art works would return is definitively gone," she said. "It would be a loss that touches every art lover."

Perhaps the only positive note is that, if Dogaru hoped to destroy the evidence, she likely failed, said Marinello. "Everything nowadays leaves a trace."
