Witnesses later testified Margot fell from her bunk in her weakened state and was killed by the shock. Anne died a day after Margot.The exact dates of Margot's and Anne's deaths were not recorded. It was long thought that their deaths occurred only a few weeks before British soldiers liberated the camp on 15 April 1945, but research in 2015 indicated that they may have died as early as February. Among other evidence, witnesses recalled that the Franks displayed typhus symptoms by 7 February, and Dutch health authorities reported that most untreated typhus victims died within 12 days of their first symptoms. Additionally, Hanneli Goslar stated her father, Hans Goslar, died one or two weeks after their first meeting; Hans died on 25 February 1945.
