Former Ruaraka OCS Nahason Mutua was, on Thursday, sentenced to death after he was charged with killing a trader Martin Koome in the station’s police cells back in 2013.
The High Court Lady Justice Stella Mutuku said the prosecution has proved its case beyond reasonable doubt.
Despite Mutua denying killing Koome on December 19, 2013, Justice Mutuku said that the evidence produced by the 18 prosecution witnesses was to prove that the police caused the deceased suffering while in cells which caused his death.
Mutua had told the court that Koome was beaten up by cellmates for noise making minutes after he was booked.
In the incidence that took place on the night of December 19, 2013, Koome succumbed to injuries sustained after being beaten by the officer at Ruaraka Police Station.
Police took him to Kenyatta National Hospital with a swollen face, deep cuts, and his wife could barely recognise him.
However, soon after the incident, the former Ruaraka commander was transfered to Machakos County to fill the position of staffing officer.
The prosecution showed the trial court how Mutua went to great lengths to obstruct justice, even offering an Sh1 million bribe to investigators besides trying to frame Odhiambo.
The case is the first high profile conviction of an officer accused of extrajudicial killing.
