Jonah Anguka is a Kenyan author and former District Commissioner at Nakuru, known as the only person to date to have been tried for the murder of Dr Robert Ouko, Kenya's Minister of Foreign Affairs, who was shot dead on 13 February 1990.
Anguka graduated from the University of Nairobi in 1977 with a degree in political science. He served in Kenya's provincial administration during which time he was given paramilitary training at the Embakasi General Service Unit (GSU) Training Centre. Later he served in various postings as a district officer before becoming the District Commissioner (DC) to Nakuru in 1986. As such he was part of Kenya's internal security and intelligence organisation and directly responsible to Hezekiah Oyugi, then the Permanent Secretary, Provincial and Internal Security.
Kenya's then Minister of Foreign Affairs, Dr Robert Ouko, was murdered on the morning of 13 February 1990, shot through the head, at the foot of Got Alila Hill, some 2.4 km from his country residence in Koru, near Kisumu, north western Kenya.
Anguka's wife, Mrs Susan Ngeso Anguka was Dr Ouko's Personal Assistant at the Ministry of Foreign Affairs. He also farmed land adjacent to Ouko's farm in Koru. Ultimately, Jonah Anguka was named in connection with the murder of Dr Ouko by five different authorities and individuals.
On 18 November 1991, at the Judicial Commission of Inquiry into Ouko's murder the former Detective Superintendent John Troon who had led Scotland Yard’s investigation (at the request of the Kenyan government) into the killing, stated that, 'There is a possibility that Mr Anguka may have some involvement or knowledge' [of the murder].
Troon was being questioned by Justice Akiwumi, Justice Gicheru and Bernard Chunga (State Prosecutor) during the Judicial Commission of Inquiry into Dr Ouko's death when he raised the case for further investigation of Anguka. The transcript of the relevant hearing explains Troon's reasoning.
