Police in Kiambu are holding a 26-year-old Kenyan man for allegedly killing his girlfriend in cold blood.

Tairus Mwangi, an Administration Police officer based in Malindi, Kilifi County, is alleged to have fatally hit his girlfriend identified as Purity Karwirwa, 26, multiple times in the head, nose and back using a hammer in Ruaka estate on Wednesday, February 26th.

The two had dated for one-and-a-half years after meeting on Facebook, the deceased’s brother, Erick Kimathi told a local media on Saturday.

“Their relationship was full of physical abuse, with the suspect often being the aggressor,” said Kimathi.

Skitter Ntinyari, a friend of the deceased, said the two constantly quarreled on phone. “Rarely would their conversations end without the two disagreeing over an issue,” said Ntinyari.

Mwangi allegedly arrived in Nairobi on Tuesday, February 25th, and asked to meet his girlfriend the next day in a bid to solve their differences.

He picked Karwirwa in Donholm, Nairobi and took her to his sister’s home in Ruaka, where they are said to have fiercely quarreled before Mwangi reached for a hammer and attacked her. Mwangi was captured on CCTV footage later that day leaving his sister’s house, having changed his clothes.

Mwangi’s sister found Karwirwa’s body lying in a pool of blood on the floor when she arrived at her house. She reported the incident at Karuri Police Station.

Detectives tracked the suspect to a bar in Kahawa West on Thursday, February 27th using his phone signal. He was arrested and booked to Karuri Police Station pending investigations and arraignment in court.

A postmortem examination done at Kihara Level 4 Hospital morgue on Friday showed the deceased succumbed to head injuries.
