Eldoret based journalist John Kituyi who was murdered as he walked to his house by assailants on boda boda had published a story touching on the case facing Deputy President William Ruto. He owned local tabloid Weekly Mirror.
It is that story which according to the Committee to Protect Journalists (CPJ) which may have led to his killing.
In the story, he narrated prospects of successful prosecution of the Deputy President by the International Criminal Court.
The Deputy President and Journalist Joshua Arap Sang still faces charges of crimes against humanity at the international criminal court related to the mass killings and displacements that accompanied Kenyaâ€™s disputed 2007 presidential election.
The trial in The Hague has been seen by legal watchers as demonstrating the limits of international tribunals in prosecuting powerful serving government officials.
The body of one witness involved in the case, Meshack Yebei, was found in March in a thicket at the Tsavo National Park. Yebei hailed from Eldoret too.
â€œWe condemn the murder of editor and publisher John Kituyi,â€ said CPJ East Africa representative Tom Rhodes. â€œAuthorities in Eldoret must work efficiently and thoroughly to prosecute the killers and demonstrate that such violence will not be tolerated.â€
