Four police officers have been charged with the murder of human rights lawyer Willie Kimani, his client and their driver at a court in Kenya's capital Nairobi.
Mr Kimani disappeared after lodging a complaint against a police officer on behalf of his client Josephat Mwendwa.
The three men were tortured before being killed.
The Law Society of Kenya called on all lawyers to boycott courts and there were nationwide protests following the murders.
The killings sparked outrage in Kenya and many blamed the police force for a series of extrajudicial killings in recent years.
The police officers will remain in custody whilst authorities complete their investigation.
All four have denied the charges
