He did not return to Kenya. The Gicheru Commission did not produce a final report. Following the disbanding of the Gicheru Commission and the onset of the Kenyan police investigation, ten government officials, including Energy Minister Nicholas Biwott and head of internal security Hezekiah Oyugi, were detained for questioning in relation to the murder. Nicholas Biwott was released after two weeks in the absence of "any evidence to support the allegations". Jonah Anguka, a District Commissioner from Nakuru, was tried for Ouko's murder in 1992 and acquitted, with the crime remaining unsolved. Anguka later fled into exile in the United States, saying he feared for his life. He has since published a book, "Absolute Power," denying his involvement in the Ouko Murder. We lost a young lawyer Advocate Masime who was part of this inquiry. In March 2003 the newly elected government of Mwai Kibaki opened a new investigation into Ouko's death to be conducted by a parliamentary select committee. During the course of the Committee's deliberations several members of parliament publicly condemned the manner of its proceedings. Some left the committee and along with others who remained declared that they would not endorse its findings. Domenico Airaghi and Marianne Briner-Mattern agreed to testify on condition that they would not be cross-examined (something they had avoided during Troon's investigation, the Public Inquiry and the further investigation by the Kenyan police) and Nicholas Biwott was not allowed to call witnesses on his behalf or cross-examine or address other witnesses. The Select Committee, however, did not complete its work. It was disbanded in 2005 on the grounds of 'interference' in its deliberations just as Nicholas Biwott was beginning his testimony to it. The (incomplete) report of the ‘Select Committee Investigating Circumstances Leading to the Death of the Late Dr. The Hon. Robert John Ouko, EGH, MP’ was never debated in the Kenyan House of Assembly, or put to a vote. Robert Ouko was married to Christabel Ouko. He had three sons, named Ken, Charlie, Andrew; and four daughters: Winnie, Susan, Lilian, and Carol. Robert Ouko also had a daughter (born May 1983) by a Miss Herine Violas Ogembo, a relationship that lasted until his death. In 2010, a fundraiser was held to build the Robert Ouko Memorial Community Library in Koru.
