In 2009, reporter Joshua Prager wrote an article in the "Wall Street Journal" profiling the long-term toll that Raoul Wallenberg's disappearance had on his family. His mother, Maj, and his stepfather, Fredrik von Dardel, spent the rest of their lives searching for their son. They both committed suicide by overdosing on pills two days apart in 1979. Their daughter, Nina Lagergren, Raoul's half-sister, attributed their suicide to their despair about never finding their son. Lagergren and Raoul's half-brother Guy von Dardel established organizations and worked to find their brother or confirmation of his death. At the request of their parents, they were to assume he was alive until the year 2000.
