Eutycus Githinji hanged himself with his shoe laces at Huruma police station, where he was remanded by a court. His body was found hanging from the window of the cells’ toilets.
Githinji, 45, was arrested last Monday, weeks after he stabbed his stepson with a kitchen knife and went into hiding.
Dennis Mwema, 18, was stabbed on May 9 at their Huruma home as he attempted to stop Githinji from beating his mother Eunice Wanza. Mwema was confirmed dead at hospital.
Wanza, 37, sustained minor injuries. She reported the matter to officers at the Huruma station.
She said Mwema was stabbed with a kitchen knife.
Wanza had been married to Githinji for eight years. He returned home drunk at 3am and the two got into a verbal altercation, which turned into a fistfight.
Mwema was asleep but woke up to rescue his mother. Githinji turned on his stepson with kicks and blows.
He dragged Mwema into the kitchen, where he stabbed him. Neighbours said they heard Wanza screaming for help.
Yesterday, Nairobi DCI chief Ireri Kamwende said police are investigating Githinji’s death.
Mwema’s case is among many where children are caught up in fights between their parents.
In March, police in Voi arrested a woman who allegedly killed her one-week-old son following a domestic squabble with her husband.
Taita Taveta police boss Fredrick Ochieng said Esther Wanjala, 27, is suspected of suffocating the baby during the fight at their home in Dambi village, Sagalla location.
