Tairus Mwangi is believed to have taken the life of Purity Karwirwa by hitting her with a hammer five times on the head and several times on different parts of the body. The 26-year-old officer is said to have met Karwirwa on Facebook over one and half years ago when they started dating, as reported by K24. According to the deceased’s brother, Erick Kimathi, Karwirwa earned a living through online freelance writing and used to stay with her friend, Skitter Ntinyari, in Donholm, Nairobi. Kimathi said the deceased used to visit her boyfriend more often in Malindi. “Their relationship was full of physical abuse, with the suspect often being the aggressor,” said Kimathi. However, according to Ntinyari, things were not going on so well in their relationship and a simple phone call could often end up with a quarrel. “Rarely would their conversations end without the two disagreeing over an issue,” said Ntinyari. On Tuesday, February 25, Mwangi travelled to Nairobi and asked to meet up with Karwirwa to iron out their issues. On February 26, Mwangi went to Donholm to pick up Karwirwa and the two left together and went to the officer’s sister’s house in Ruaka. The two are said to have quarrelled again before Mwangi allegedly reached out for a hammer and hit Karwirwa in the head, nose and back, killing her on the spot. Mwangi then changed her clothes and left her sister’s as was seen in a CCTV footage obtained from the scene of crime. The suspect’s sister, who arrived at her house on Wednesday evening, was shocked to find Karwirwa’s body lying in a pool of blood on the floor. She reported the incident at the Karuri Police Station, prompting a hunt for the suspect, who had escaped to an unknown destination. Detectives from the Directorate of Criminal Investigations (DCI) managed to track down the warden who was later arrested at a club in Kahawa West and taken into custody at Karuri Police Station. A postmortem examination on Karwirwa’s body, which was conducted on Friday, February 28, at the Kihara Level 4 Hospital morgue, indicated the 26-year-old died from inflicted head injuries. The body was transported on Sartuday, February 29, to their home in Mwanika village in Central Imenti in Meru county for burial. The suspect is set to be arraigned on Monday, March 2, as investigations continue.
