The 1975 murder of politician Josiah Mwangi Kariuki (J.M. Kariuki) remains one of the most politically significant unresolved assassinations in Kenya's history. At the centre of the parliamentary effort to establish what happened was Elijah Wasike Mwangale, the MP who chaired the Select Committee appointed to investigate Kariuki's disappearance and murder.
Kariuki, then the MP for Nyandarua North, disappeared in February 1975. His body was later discovered in the Ngong Hills on March 2, triggering public outrage and intense pressure on President Jomo Kenyatta's government to establish who was responsible.
Parliament responded by establishing a Select Committee on March 14, 1975. Mwangale was appointed chairman. The committee's report, published in 1975, is now preserved in the Parliament of Kenya's official library and runs to 76 pages.
Mwangale's investigation
The committee interviewed a large number of witnesses and examined the movements of people believed to have had information about Kariuki's final hours.
Its investigation was complicated by what it described as a lack of cooperation from senior police officers. The committee concluded that the refusal by police leadership to provide assistance and information had seriously hampered its work. It went as far as stating that the police investigators appeared unwilling to assist efforts to bring Kariuki's killers to justice.
One of the most significant figures examined was Ben Gethi, then a senior General Service Unit commander. According to the committee's findings, Gethi was the last person known to have been seen with Kariuki after the two left the Hilton Hotel.
The committee considered Gethi's role sufficiently serious to recommend that he be suspended from duty while a fresh investigation was conducted.
A later academic biography of Mwangale records that the committee believed Gethi could have participated directly in the killing or acted as an accomplice.
Other people the committee wanted investigated
The committee did not simply focus on Gethi. It identified several people whose movements and activities required further investigation.
Among those mentioned were Silas Mburu Gichua, then Mayor of Nakuru; John Mutung'u, a councillor in the Ol Kejuado area; Stanley Thuo, then Nyandarua District Commissioner; Waruhiu Itote, popularly known as General China and then Deputy Director of the National Youth Service; and Arthur Wanyoike Thungu, who was associated with President Kenyatta's security arrangements.
The committee also raised questions concerning Mbiyu Koinange, a powerful minister and close associate of President Kenyatta, as well as individuals connected to him.
These recommendations did not amount to judicial findings of guilt; rather, they identified people whose roles, movements or activities the committee believed required further investigation.
The dramatic State House episode
The most controversial chapter came when the committee completed its report.
Historical accounts indicate that on June 3, 1975, as Mwangale and his fellow committee members were preparing to table their findings in Parliament, they were summoned to State House.
Mwangale reportedly went there with a copy of the report while other copies remained in Parliament.
The subsequent history of the report became a major political controversy. The Truth, Justice and Reconciliation Commission (TJRC) later concluded that President Kenyatta had interfered with the parliamentary investigation and specifically ordered the removal of the names of Mbiyu Koinange and Arthur Wanyoike Thungu from the report because of their links to the Office of the President.
The TJRC's finding is particularly important because it provides a later official assessment of what happened to the original parliamentary investigation.
What ultimately happened?
The report did not result in successful prosecutions of those implicated or recommended for further investigation.
The matter effectively stalled, despite the committee's serious concerns about the conduct of senior police and government officials.
Decades later, the TJRC revisited the assassination. It concluded that Kariuki had been killed for political reasons and found credible evidence that state officials, including members of the police and Special Branch, were directly involved.
It also identified several people as having sufficient evidence against them concerning the assassination or its subsequent cover-up.
The commission recommended that the government reopen investigations into Kariuki's assassination, paying particular attention to people identified by both the Mwangale Committee and the TJRC.
Mwangale's role therefore remains central to the history of the case. His committee produced one of the earliest major official attempts to penetrate the circumstances surrounding Kariuki's killing, but its findings collided with powerful political interests.
The report survived as a parliamentary record, yet the murder itself remained without a definitive judicial resolution.
The Mwangale Committee report is available in the Parliament of Kenya's digital repository, providing an important primary source for examining the allegations and recommendations made in 1975.
