Christian Didier (11 February 1944 - 14 May 2015) came to public attention after 8 June 1993 as the assassin of René Bousquet, a friend of French President François Mitterrand who had served as a senior police official under Vichy France, which administered the southern half of France during the German occupation.
Directly after the killing, Didier telephoned a succession of newspaper editors in order to organise an ad hoc press conference.
This meant that the police had no difficulty in locating him.In 2013 Didier sued an author for defamation after the author, in a biographical book on René Bousquet, described Didier as "fou" ("crazy", "mad").
The book had already triggered a legal case alleging plagiarism.
In the end the plagiarism charge succeeded and damages of several thousand Euros were awarded.
