A woman is in police custody for the allegedly murdering her husband for arriving home late and drunk.

Ann Mbaithe allegedly stabbed 30 year old Daniel Githuka in the chest after he returned home in the wee hours of Saturday.

The couple lived in Tinganga village, Kiambu town.

Githuka’s mother Elizabeth Wanjiku said he worked at a neighbouring school and usually returned at about 10pm.

She revealed that the couple had been married for five years and had no problems. They had a four year old child together.

“My son and I live in the same compound. I heard confrontation from my house past midnight,” Wanjiku said.

According to Elizabeth, she got out of bed and went to Githuka’s house where she found him arguing with his wife.

The Star reports that Mr Githuka stood his ground and declared he was the head of the house who should not have been confronted over the matter.

The mother added that she had not noticed the knife Mbaithe had been holding since she was standing at akimbo.

“It was not a physical confrontation but my son’s wife suddenly attacked and stabbed him in the chest with a knife,” she said.

“After my son was stabbed I called for help from neighbours but upon reaching hospital he was pronounced dead due to loss of blood.”

Mbaithe was arrested after Wanjiku reported the matter at Kiambu police station.

County DCI boss Amos Tebeny said Mbaithe will be charged with murder once investigations are completed.
