Carolina Mok-Peper and her husband Jack Samuel were in hiding on the Fraunhoferstraat in Amsterdam. On 6 August 1943 two members of the Kolonne Henneicke rang the doorbell and entered using the excuse that they wanted shelter because of the air raid alarm. They took the Mok-Peper family away with them.
