>> It's the ultimate cold case. Who betrayed Anne Frank and her family? It's been 70 years since Nazis stormed their hiding place, this canal house annex in Amsterdam and sent the youngster to her death in a concentration camp. After so long, forensic evidence is gone, and witnesses are dead.
But, a newly formed team of investigators think that they can use advances in technology to crack the case.>> We immediately were blown away when we realized the amount of data and historical archives that needed to be investigated. This is over 25 kilometers of files, you are talking about what should be related directly to the investigation.
>> Extensive data and modern policing techniques could provide new leads. A master database will be compiled detailing Nazi collaborators, informants, documents, and police records. Headed up by a former FBI agent, the team are looking for answers, but not prosecution. They're hoping to complete by the fourth of August 2019 to mark 75 years since Anne Frank's arrest.
She was discovered in 1944 after two years in hiding. Police investigations in the decades that followed focused too narrowly on one individual, warehouse manager Willem van Maaren, without examining alternative scenarios. Historians on the subject are also mucking in, as well as the Anne Frank Foundation and data companies on there.
They say they want to see an end to what's been coined the cold case diary.
