The Art Newspaper reported last October that the US authorities began repatriation proceedings after the work was certified by a Venezuelan authentication committee and later confirmed by the director of the Henri Matisse Archives in Paris, Wanda de Guébriant.

According to the affidavit filed in support of the criminal complaint, this case was the result of an FBI undercover investigation. According to the allegations in the complaint affidavit, Marcuello negotiated the sale of the Matisse painting, which had been previously stolen from the Caracas Museum of Contemporary Art (Museo de Arte Contemporaneo de Caracas (MACCSI)) in Caracas, Venezuela in December 2002. The painting is valued at approximately $3 million. Marcuello allegedly admitted to the undercover agents during a meeting that he knew the painting was stolen and offered to sell the stolen painting for approximately $740,000.00. As part of the negotiations, Marcuello further agreed to have the painting transported by courier to the United States from Mexico, where the painting was being stored. The courier was subsequently identified as co-defendant Ornelas. According to the affidavit, on July 16, 2012, Ornelas arrived at the Miami International Airport from Mexico City, Mexico, hand-carrying a red tube containing the painting. On July 17, 2012, defendants Marcuello and Ornelas met with undercover agents and produced the Matisse painting titled “Odalisque in Red Pants” from inside the red tube. Upon inspection by the undercover agents, the painting appeared consistent with the original Henri Matisse painting reported stolen from the MACCSI museum. At the conclusion of the meeting, Marcuello and Ornelas were arrested.

A press conference in Augsburg shows some of the 1,406 unknown works of art found in a Munich apartment in 2012. They include works by Matisse, Marc Chagall, and Otto Dix. Reinhard Nemetz, Augsburg state prosecutor, said (translated from German to English with subtitles provided by The Guardian): A total of 121 framed and 1,285 non-framed works, among them from famous artists, were seized. There were oil paintings, others in Indian ink, pencil, water colours, colour prints, other prints from artists like Max Liebermann and others. Dr. Meike Hoffmann, Berlin’s Free University, said (in English): “Of course, it was very emotional for me to see the works of art and to recognize that they exist but not comment to the value of the collection.

Treasures discovered during a raid on Cornelius Gurlitt's flat in Schwabing include a total of 1,406 works – 121 of them framed – by Franz Marc; Oskar Kokoschka; Henri de Toulouse-Lautrec; Max Liebermann; Ernst Ludwig Kirchner; Max Beckmann; Albrecht Dürer; a Canaletto sketch of Padua; a Carl Spitzweg etching of a couple playing music; a Gustave Courbet painting of a girl with a goat; and drawings and prints by Pablo Picasso.

Art historian Meike Hoffmann, of the Free University of Berlin, said the art world would be particularly excited about the discovery of a valuable Matisse painting from around 1920 and works that were previously unknown or unseen: an Otto Dix self-portrait dated around 1919, and a Chagall gouache painting of an "allegorical scene" with a man kissing a woman wearing a sheep's head.

The emergence of old masters such as Dürer and Canaletto among the modernists further complicates the picture of the extraordinary art collection. Initial speculation had been that most of the pictures were "degenerate art" looted or confiscated by the Nazis. Now it looks likely that at least some were purchased by Cornelius Gurlitt's father, thus making him the rightful owner. One painting, by Gustave Courbet, was auctioned off -- presumably to Gurlitt senior -- as late as 1949. Hoffmann said that determining which of the works have to be returned to the descendants of their rightful owners could take a long time.

Hoffmann said she had only properly examined 500 works and could therefore not comment on the entire collection. "With the works I have done research on, I am assuming that they are authentic works. But that's just my personal assessment."

A list of art compiled by U.S. troops in 1950 may help Jewish heirs identify works looted by the Nazis that wound up in a squalid Munich apartment, researchers from the Holocaust Art Restitution Project said. U.S. troops vetted Heldebrand Gurlitt's collection -- including works by Max Beckmann and Edgar Degas -- and handed it back to him 63 years ago, according to a custody receipt that Marc Masurovsky and Willi Korte, researchers at HARP, found yesterday in the National Archive in Washington.

Matisse painting stolen from Kunsthal Rotterdam

Police believe the unnamed woman, the girlfriend of the 28-year-old, was living in the flat where the canvases were stored until they had been removed from their frames and transported to Romania.

Investigation following the art theft at the Kunsthal gallery in Rotterdam has shown that the suspects entered through a door at the back of the building. They seized and made off with the paintings in a very short space of time. The collection and examination of camera footage is now in full swing, as is the rest of the criminal investigation. So far no images have been found which are suitable for publication.

Burglars stole seven art works from the Kunsthal at Westzeedijk in the course of the night between Monday and Tuesday. They forced their way into the building at about quarter past three in the morning and were outside again very soon after.

The alarm went off at the security company, whereupon police and security personnel launched an investigation. There were no visible signs of forced entry outside the premises. Nor was anyone present inside the building.

Security personnel only discovered the paintings were gone after they went inside the building.

Forensic detectives made a thorough investigation, carefully securing any clues and evidence both inside the Kunsthal and in the immediate vicinity. They were able to establish how the perpetrators gained access to the building without leaving any sign of forced entry.

The Kunsthal contacted the owner of the works in question. On Tuesday morning the Kunsthal submitted an official report to the police as soon as it was ascertained for certain which paintings were involved. The publication of images attracted world-wide attention to the robbery and the stolen paintings. An international alert was also issued for the pictures.

Apart from images from inside the Kunsthal itself, camera images of the immediate vicinity were also secured. All images are being studied carefully by the detectives. So far no camera images suitable for publication have been found.

The Dutch television programme 'Opsporing Verzocht' also drew attention to the case on Tuesday evening. Images of the stolen paintings were shown during the programme.

Thanks to all the media attention, dozens of tips were received and are being investigated for their usability.

The team spoke to various witnesses. All information is still welcome. The investigators are making a particular appeal to the visitors to the Kunsthal. Did you visit the Kunsthal last week and did you see or hear anything unusual while you were there? Did you take any photos or video pictures? If so you should contact the police on 0900-8844. If you would prefer to speak to the Criminal Information Unit call 079-3458999. We would also like to speak to you if you saw any suspicious vehicles or persons in the vicinity of the Kunsthal in the period immediately leading up to the art theft.
