Imbatu has been described by colleagues, close friends and neighbours as a quiet man whose mind you could read. The 53-year-old opened fire on seven people - killing five and seriously injuring two others. Speaking on condition of anonymity to a local media, nightguards manning J Heights Apartments in Kangemi said even though he was a quiet person, he was always full of anger.
On Tuesday, rogue police officer Benson Imbatu went berserk and sprayed his lover Carol with bullets and then killed five other people, before turning the gun on himself. According to reports, Imbatu and Carol started dating in September and had only lived together for one month.
