Q: (CNN) -- Nick Heidfeld has left his role as reserve driver at Mercedes to become a tester for Pirelli ahead of the Italian company's return to Formula One as the sport's sole tire supplier next year.

The 33-year-old German had driven in F1 for a decade but was left without a seat when BMW ended its association with the Sauber team at the end of last season.

He was given a lifeline when Mercedes took over the world champion Brawn GP team this year, becoming back-up to returning seven-time world champion Michael Schumacher and Nico Rosberg.

"I would like to thank Ross Brawn, Norbert Haug and Nick Fry for allowing me the opportunity to become Pirelli's official test driver," Heidfeld told F1's official website.

"The team has always said that they would not stand in my way if such a chance arose, and they have kindly allowed me to take up this exciting new role."

Mercedes team principal Ross Brawn said: "Nick is an extremely experienced driver and we are confident that his racing knowledge and technical feedback will prove extremely useful to Pirelli and therefore of benefit to the sport as a whole."

Mercedes-Benz Motorsport vice-president Haug said the move might help Heidfeld find a drive for 2011.

"It would be great to see Nick in a competitive car in next year's world championship and I am sure his leading role in the new tire development, in addition to his skills, puts him in a good position for the remaining seats in 2011," Haug said.

Q: NEW YORK (CNN) -- An oil painting was returned Tuesday to the estate of a Jewish art dealer who was forced to consign the painting and other artwork under Nazi Germany before fleeing the country.

"Portrait of a Musician Playing a Bagpipe" was done in 1632 by an unknown artist.

The painting, "Portrait of a Musician Playing a Bagpipe," was done in 1632 by an unknown painter from the Northern Netherlandish school, according to a statement from the U.S. attorney's office in southern New York.

It was owned by Max Stern, an art dealer who had a gallery in Dusseldorf, Germany, until 1937, when the Nazis' Reich Chamber for Fine Arts ordered him to liquidate the gallery and its inventory, the statement said.

Stern, who died in 1987, left no heirs. He and his wife had founded the Max Stern Art Restitution Project, which directly benefits Concordia University and McGill University in Montreal, Canada, and Hebrew University in Jerusalem, according to a statement from U.S Immigration and Customs Enforcement.

The painting was returned Tuesday -- Holocaust Remembrance Day -- to Clarence Epstein of Concordia University on behalf of the executors of the estate, said Lou Martinez of the immigration agency.

It was returned in a ceremony at the Museum of Jewish Heritage in New York, he said.

The painting had been owned by Philip Mould Ltd., a London, England, gallery, when Lawrence Steigrad, a New York art dealer, bought it in 2008, the New York attorney's office said.

Neither had any idea of the painting's past. Philip Mould Ltd. had purchased the painting the year before from Lempertz Auction House. The same auction house sold the painting in 1937 after Stern was forced to liquidate, without receiving any proceeds from the sale, the New York attorney's office said.

Q: (CNN) -- A body discovered at Churchill Downs on Sunday, a day after the storied Louisville racetrack hosted the Kentucky Derby, may have been the victim of a homicide, police said.

Workers in the barn area discovered the body early in the morning and notified track security, which called police, said Robert Biven, a spokesman for the Louisville Metropolitan Police Department.

"We just got the call just prior to 5 a.m. to respond to the backside" of the racetrack, Biven told CNN.

Police spokeswoman Alicia Smiley said police suspect foul play.

The body, which has not been identified, appears to be a Latino man in his 30s or 40s, Biven said.

About 400 people were located Saturday night in the rear of the racetrack, he said. "So we are trying to speak with as many people as we possibly can," he said. "We do have a few leads coming in." An autopsy is to be carried out Monday morning.

Biven described the track's backside as "like a mini city," with 48 barns, workers' dormitories and areas where trainers live. "It's a 24-hour operation," he said.

Operations at the racetrack were to continue normally on Sunday, Churchill Downs spokesman John Asher said. No races are scheduled at the track for three days, but cleanup from Saturday's race was to continue and the racetrack museum was to be open, he said.
