A historical investigation carried out in the USA identified the alleged informer who betrayed Anne Frank, a very young victim of the Holocaust made famous by the intimate diary written during the German occupation of Holland in the Second World War, more than 75 years later, effectively selling her to Nazis together with his family to try to save their own. The man would be Arnold van den Bergh, a member of the Jewish community of Amsterdam, and his name came to light as that of the "probable" responsible for the capture of Anna (who later died at the age of fifteen in an extermination camp in 1945) at the end of 6 years of research conducted by a team of historians, experts and even a former FBI detective.
The investigation made use of modern methods used today for the reopening of a so-called 'cold case', a criminal case that has been unsolved for years: including computerized algorithms capable of digging into the historical connections between numerous people, as reported by the international media. Van den Bergh was a member of the Jewish Council, a collaborationist organization made available to facilitate the implementation of the Nazi occupation policy, except in any case to be dismantled in 1943 with the final dispatch of its members to concentration camps. He would have betrayed the Frank family, "after losing a series of protections and finding himself in the need to offer some valuable information to the Nazis, to try to keep himself and his wife safe," said Vince Pankoke, a former agent of theFbi and member of the investigative team, in an interview with 60 Minutes by the American CBS, taken up by the BBC, among others.
