The family of World War II hero Raoul Wallenberg says it will ask President Barack Obama for help in their quest to find out what happened to the Swedish diplomat who vanished after being arrested by Soviet forces in 1945.
Wallenberg's niece, Marie Depuy, told The Associated Press the family will present a letter to Obama at a memorial ceremony for Wallenberg that the president is attending Wednesday in Stockholm.
The letter, a copy of which was given to the AP, asks the U.S. to pressure Russia to open archives that could shed light on Wallenberg's fate.
Wallenberg, working as Sweden's envoy in Nazi-occupied Hungary but also secretly for the U.S. War Refugee Board, managed to save thousands of Jews. The time and circumstances of his death remain a mystery.
