Convicts in the murder of human rights lawyer Willie Kimani will be sentenced on November 11.
The case was adjourned on Friday because Justice Jessie Lessit was indisposed.
In July, Lessit convicted three police officers and a police informer for the murder of Willie, his driver Joseph Muiruri and his client Josephat Mwenda.
Police officers Fredrick Leliman, Stephen Cheburet, Sylvia Wanjiku, Leonard Mwangi and police informer Peter Ngugi are expected to the sentenced after being found guilty of the murder.
Justice Lessit had set the matter for mention on Friday to confirm whether the probation reports were ready, but she was not available.
Officer Leonard Mwangi was acquitted of all the murder charges and was released.
The case was mentioned before presiding judge Kanyi Kimondo, who gave a new mention date on November 11 before Justice Lessit.
The court is expected to receive the victim impact statement and probation report that will help the court when sentencing of the four convicts.
The defence will also be given an opportunity to mitigate before the judge sentences the convicts.
Willie, who was a lawyer working with International Justice Mission, was brutally murdered alongside Mwenda and Muiruri on June 23, 2016.
The three victims were abducted from their car as they left Mavoko law courts, where Willie had gone with Mwenda, his client.
Their bodies were later found dumped at the Oldonyo Sabuk River wrapped in black gunny bags.
According to police, after their abduction, they were held for a few hours at Syokimau police post before they were taken to a field where they were killed.
The prosecution had asked the court to convict all the accused persons, saying they each played a part in the murder.
The state told the court they had proved beyond all reasonable doubt that all the five accused planned the brutal killing of the victims.
Judge Lessit said the prosecution had proved beyond reasonable doubt that the four were guilty.
Lessit analysed a total of 117 exhibits and evidence given by 46 prosecution witnesses and 34 defence witnesses to reach her decision.
The judge had told the court that she had written more than 6,000 pages of proceedings since the trial started and it was the biggest file in her career.
Some of the crucial exhibits the judge has analysed included phone data records, mobile phone companies' cell sites analysis and DNA samples of the accused persons.
Others were the confession statement given by Ngugi and evidence generated from CCTV cameras from the high-tech Communication Command Centre (C3) and motor vehicle recognition technology.
In the confession that implicated Leliman and Mwangi, the police informer said Leliman was the one who killed the victims while Mwangi alongside an unknown officer put the bodies in the boot.
During his defence, Ngugi made a further confession orally that he was used by the officers to commit the crime.
He confessed that the plan to kill the victims was hatched by officers from Mlolongo police station.
He told the court that after dumping the bodies of Kimani, Josephat Mwenda and Joseph, they were hosted by Leliman and his wife at his bar in Mlolongo.
He said Leliman’s wife, Esther Muthama, also a police officer, served them beer and 5kg of fried beef.
“There were two ladies serving us at the bar. I saw one in court the other day and she said she was Leliman's wife," Ngugi said.
Asked how he knew that was Leliman’s wife, Ngugi said he tried to seduce her before Leliman arrived, but was cautioned by officer Wilson Kamau that “that’s mzee’s wife.”
Ngugi said he was also afraid and could not mention Leliman before because, when they were arrested his wife and Leliman’s wife met in court and exchanged numbers, so at that point, his family got exposed.
