'Til Death Did Them Part
 
In 1996, Paris police set out to investigate a late night, high speed car crash, both drivers had been killed instantly.

Investigations revealed that the deceased were in fact man and wife.

Police initially suspected some kind of murder or suicide pact but it became apparent that the pair had been separated for several months - neither could have known that the other would have been out driving that night - it was just a terrible coincidence.
