The incident happened on Tuesday evening at 11 pm.

According to the police occurrence book (OB), Nduati, who was on duty at the time of the shooting incident, killed the girlfriend and her son before surrendering his G3 rifle to officers manning the main gate.

He is said to have confessed to murdering the girlfriend.
