Betrayal of Anne Frank - Conclusions in The 2003 Investigation

Conclusions in The 2003 Investigation

The Netherlands Institute for War Documentation (NIOD) reopened their archives in light of two new theories about the betrayal of Anne Frank. The first, in Melissa Muller's Anne Frank: the Biography asserted a claim against Lena van Hartog. The second, in Carol Ann Lee's The Hidden Life of Otto Frank, concluded that Tonny Ahlers was indeed guilty. As both were supported solely by circumstantial evidence, neither could be substantiated. NIOD concluded that the betrayer's identity is still unknown.
