On August 4, 2019 it was 75 years since the raid that took away the Frank and Van Pels families, and Fritz Pfeffer. Although it was subjected to several investigations, the circumstances that led to the raid have never been fully discovered. This new investigation uses modern law enforcement investigative techniques, methods of cold case detectives, and testimonial reconstruction.

The Cold Case Team is comprised of numerous professionals, each aiding in their areas of specialization/expertise. Our team of historians, psychologists, profilers, data analysts, forensic scientists and criminologists are assisted by subject matter experts of various backgrounds. Among them former Unit Chief dr. Roger Depue, one of the founding members of the FBI Behavioral Science Unit. This way new light will be shed on the events, making it possible for the Cold Case Team to go back in time and make this cold case hot again.

The public's assistance in solving cold cases is very important. Do you have any information that can help the Cold Case Team to solve the question: What led to the raid on the Secret Annex? Please submit your information here.
