A picture dated March 1992 shows former US ambassador to Kenya Smith Hempstone during a press conference in Nairobi. Kenya's President Daniel arap Moi and an influential cabinet minister were suing Hempstone Smith for linking them to the 1990 killing of foreign minister Robet Ouko. Moi, in a lawsuit filed in the High Court 30 July and obtained by AFP 31 July 2001, alleged that former US envoy Smith Hempstone libelled him in his memoir, Rogue Ambassador, published in 1997.
