But there was one witness whose testimony changed dramatically – James Onyango K’Oyoo – described by The Weekly Review as “One of the most sensational witnesses so far”.

K’oyoo was a neighbour and a friend of Dr Robert Ouko and one of his campaign managers during the 1988 election.

In March and April 1990 K’Oyoo gave two written statements to the police. Neither made any mention of a possible motive for Ouko’s murder, or of who may have killed him.

Over a year later when he began giving testimony to the Gicheru Inquiry, his story remained the same.

But suddenly K’Oyoo made a plea to the Commissioners for his protection. There after his story changed completely.
