Veteran politician Tom Mboya's name went down among the political leaders who were controversially assassinated and whose death probes are yet to be finalized on.
Then a minister in then President Jomo Kenyatta's government, Mboya was leaving a Chemist along Nairobi's Government Road (now Moi Avenue) on Saturday, July 5, 1969, when he was shot dead in broad daylight.
Though the main reason behind his murder is yet to be known, his suspected killer would later be identified as Nahashon Isaac Njenga Njoroge, who would later be sentenced to death for the crime.
Njenga, however, despite hinting that he was working under someone else's orders, never mentioned the 'big man' who sent him, only asking about the fate of the 'big man' while being sentenced to hang.
"What about the big man?" the one time youth winger during the fallen independence KANU regime asked the court, after pleading guilty to murdering the leader who was walking to his car parked outside Chhani's chemist.
The question threw journalists and historians into speculations, with the man yet to be identified 49 years down the line, though some would say he was most likely a top official in the then President Kenyatta's government.
The speculation was further propagated at the time by the fact that Njenga would only be arrested after riots erupted in Kisumu and Nairobi.
