Kiambu university girl stabbed grandmother 17 times, cleaned murder scene and became spectator

A third year student is being held as the main suspect in the murder of her wealthy grandmother in Githunguri, Kiambu County over four months ago. The murder almost went cold until the family hired a private investigator leading to the arrest of father and daughter. Mercy Wangari, a lithe 22- year-old even led detectives to where the murder weapon – a twisted metal rod- was dumped.

Mercy told investigators that she bludgeoned Beatrice Wangari Karanja, her 72-year-old grandmother  to death, cleaned the scene, vanished, then re-appeared after the alarm was raised in the sleepy Kamwanya village.
Mercy’s father, had confessed to killing his mother but later disowned his statement in a murder case that is opening the lid on domestic feuds, family favouritism and bad blood over inheritance.
Both father and daughter are being treated as suspects.
