The Prosecution called 30 witnesses and adduced ten exhibits during the trial.

It is alleged that they committed the offence on the night of November 17, 2013 at Porkies Garden Restaurant in Thika Town within Kiambu County with others not before court.

They denied the charge when arraigned in court for plea on January 14, 2014.

"I have considered the prosecution case and l'm satisfied that accused persons have a case to answer and each is placed on their defence," ruled judge Korir. 

The defence lawyers said the accused will give sworn evidence. The hearing of defence is scheduled to start on February 14.

Prosecution witnesses included a pathologist who conducted a postmortem in South Africa. Others were Thuo's widow.

The investigating officer Maxwel Otieno testified that Thuo was poisoned through drinks at Porkies bar in Thika town.

Mr Otieno told Justice Korir detectives took bottles of Tusker beer and the clothes which the deceased was wearing to the Government Chemistry where the result revealed that Thuo was poisoned.

He said that Dr Peter Ndegwa, who conducted a postmortem on Thuo's body, informed him that the deceased was poisoned and that he died due to excessive bleeding.
