Abstract:
A drunk car driver was involved in a fatal crash with a scooter at night. Examination of the lightbulbs from the vehicles revealed some mechanical and analytical incompatibilities. The laboratory's initial observations led to complementary police investigations which finally solved the first incompatibility. The different precautions taken by the technical police investigators on the crime scene finally allowed the forensic scientists to establish the functional state of the lightbulbs during the crash.
