A 32-year-old woman on Tuesday killed her husband and their two children before committing suicide at their home in Thome estate, Nairobi.
Police said preliminary findings had shown the couple was embroiled in recurrent domestic disputes, adding that the man aged 37 had several times reported about being beaten by the wife.
The woman, who was a food trader, descended on the man with an axe and struck him to death as he slept because the body was found on his bed.
The woman then strangled to death their two children aged 14 and three years before hanging herself with a rope in the house.
The bodies of the four were discovered on Tuesday afternoon after customers who used to buy food from the woman at a construction site raised queries over her whereabouts.
The bodies were moved to City Mortuary as investigations go on.
Meanwhile, two female students at St. George Katheka High School in Machakos County are nursing serious injuries after sustaining burns in a dormitory fire.
The victims who include a Form 1 and Form 2 girl, were sleeping when the dormitory caught fire on Friday last week in a suspected arson case that saw eight students arrested.
The girls were rescued and taken to Machakos Level Five Hospital where they were admitted with 57% burn on their legs, police said. The school has since been closed.
