French authorities keep Princess Diana crash investigation sealed until 2082

French authorities are keeping secret documents about Princess Diana's 1997 car crash in Paris. The investigation file will remain sealed until at least 2082, which is 75 years after police finished their work in 2007. The dossier contains over 6,000 documents, including witness statements and photographs from the crash scene. It is stored in a secure basement at the Paris Court of Appeal and protected by armed officers. French law automatically seals sensitive investigation files for 75 years to protect privacy. However, authorities can extend this period indefinitely if they choose. The sealed file has caused public frustration, as many people believe the government is hiding information about Diana's death. Conspiracy theories about the crash have circulated for decades, and this decision means the official French findings may never become public.
