After Sedov's death, Trotsky initiated an investigation of Etienne and entrusted the matter to Rudolf Klement, his one-time aide and organizer of Trotsky's Fourth International.
It has also been suggested that he was the mastermind behind the murder-decapitation of the Trotskyist leader of the Fourth International, Rudolf Klement, in France in July 1938, and the murder of the defector Georges Agabekov in France in 1937.
