A former Administration Police (AP) officer, Patrick Marwa, has been sentenced to 40 years in prison after being convicted of murdering his colleague, Dancun Cheruiyot, during a disciplinary dispute in Samburu County.The High Court in Nanyuki found Marwa guilty of murder under Section 203 and 204 of the Penal Code, citing malice aforethought.

The incident occurred on May 4, 2019, at Maralal camp's main gate, where Marwa shot Cheruiyot ten times with a G3 rifle after an argument over duty assignments.

Prosecutors, led by Esther Kimani, Jackson Motende, and Maina Kimaru, secured the conviction following evidence including witness testimonies, a post-mortem report confirming ten gunshot wounds, and recovered cartridges.Justice Anthony Ndungu emphasized that the prosecution proved Marwa's intent to unlawfully cause death.The case highlights internal police conflicts and the severe consequences of violent disputes within law enforcement.Marwa surrendered the weapon after the shooting, but the incident sparked questions about disciplinary processes and officer conduct.
