OSLO, Norway, Feb. 2 (UPI) --
Valentines Day is also trial day for six people charged with stealing "The Scream" from Oslo's Munch Museum in August 2004.
Five of the defendants are charged with aggravated robbery and the sixth faces charges of dealing in stolen goods. All have pleaded innocent.
The trial is expected to last five weeks, the BBC reported Thursday.
"The Scream" and "Madonna," both painted by Edvard Munch, have not been seen since they were ripped from the walls during a daring daylight raid on the museum.
"We still hope to find these paintings," prosecutor Morten Hojem Ervik said. "It is still possible to solve this case."
