Willie Kimani murder: A timeline

Human Rights lawyer Mr Willie Kimani whose body and that of his client Josephat Mwenda, and driver Joseph Muiruri were found in Ol-Donyo Sabuk, Athi River.

In 2016, three men – lawyer Willie Kimani, his client Josephat Mwenda and their taxi driver Joseph Muiruri – disappeared after they were last seen at a police station in Syokimau. That morning, Kimani and Mwenda had attended a court session in Mavoko for a case Mwenda had filed a against a police officer. Two weeks later, the bodies of the three men were found nearly 100km away in a river in Ol Donyo Sabuk.

Four Administration Police officers and a police informant, Peter Kamau, were charged with their murder. The officers -- Sylvia Wanjohi, Fredrick Lelliman, Stephen Cheburet and Leonard Mwangi -- and Mr Kamau will know their fate today.

Here is a timeline of the events leading up to and following the murders:


April 10: Josephat Mwenda is stopped by police officer Fredrick Lelliman, who accidentally shoots him in the hand. Three days later, Mwenda is charged with three counts: drug possession, gambling and resisting arrest.

Mwenda files a complaint against the officer at the Independent Policing Oversight Authority (IPOA) and lawyer Willie Kimani begins investigating the case on behalf of International Justice Mission (IJM), an international NGO that helps vulnerable people get justice

December 14: Lelliman and other police officers abduct Mwenda from his home at night. The next day, Mwenda is charged with six additional counts of traffic violations. Lelliman claims Mwenda was violating the law while riding a motorcycle despite the fact that his gunshot injury to his hand prevented him from doing so.


February 14: IJM officially takes on Mwenda's case. Lawyer Willie Kimani is assigned to represent him. 

Later the same month, Mwenda, his co-accused and lawyer Kimani are detained after a court hearing by police officers who say they want to question the men about a robbery with violence case that had happened in Meru. They are held for several hours and then released with no further explanation. 

February 24: IJM writes to the office of the Inspector General of Police, IPOA and the Witness Protection Agency (WPA) to complain of Lelliman’s misconduct and to request protection for Mwenda. 

March 1: WPA decision on witness protection for Mwenda remains pending because he is an accused in the ongoing court case and not a victim, thus the law does not guarantee him protection.

March 16: IPOA summons Lelliman to submit a statement about the claims of misconduct.

June 23: Lawyer Kimani, Mwenda and their taxi driver Joseph Muiruri are abducted after leaving court following a hearing on the traffic violation charges. The three are held in a police container at the station without being booked. Kimani manages to scribble a note on a piece of tissue. In it, he notes down the number of his client's wife and asks whoever sees it to tell her to get help. 

“Tafadhali pigia 079*** (Rebeka) mwambie aambie Rose Willie na Mwenda wameshikwa na wako Syokimau kwa Chief wako hatarini,” the note says. The note is thrown out of the container's window. It is later found by a motorcycle rider. 

The rider attempts to call Mwenda's wife, but she did not pick it as she did not recognise the number. He throws away the tissue. By that evening, the IJM team mounts a search to find them, going to police stations and calling out their names, but they had been removed from the station at 7:30pm, prior to the time IJM staff arrived. 

It's estimated that the three men were killed at about 10:00pm.

June 24-29: A missing persons report is filed. IJM staff and police continue to search in police stations and morgues. The men's mobile phones are found scattered. Details of the story enter the public sphere creating uproar. Lawyers in Kenya go on strike. IJM and Police Reforms Working Group (PRWG) publish a press release June 29.

June 30-July 1: The bodies of Willie, Joseph and Josephat are discovered in a river in Ol Donyo Sabuk, Machakos County.

June 30: The Law Society of Kenya (LSK) files a habeas corpus application requiring persons in police custody to be produced in court. The application seeks to have the three missing men produced alive or dead (at this point, the discovery of their bodies had not been announced). 

Later, the bodies are positively identified and IJM holds a press conference to announce the deaths. A post-mortem later found that a boulder may have been used to crush Kimani's skull. 

July 1-5: Four police officers are detained in connection with the killings.

July 4-8: Lawyers strike and hold marches to protest extrajudicial killings. IJM staff join LSK in the marches.

July 8: Memorial service for Willie, Joseph and Josephat. Gary Haugen, the CEO of IJM, speaks.
