A pregnant teen stabbed her boyfriend to death on Tuesday evening after he posted the photo of another woman on his Facebook wall.

Police said the 19-year-old used a kitchen knife to kill Kelvin Ikatwa, 25, at 3.30pm, moments after he arrived at her house in Kangemi.

Kelvin, popularly known as Razor, was a third-year University of Nairobi student.

Nairobi Police chief Japheth Koome said the couple’s landlord called officers, informing them of the fight and that Kelvin was lying in a pool of blood at the doorstep.

STABBED IN NECK

“When the officers arrived at the scene, the man was already dead and the woman was sitting next to the body. He had been stabbed in the neck. The knife was found at the scene,” Mr Koome said.

Kelvin, a player with Wazito FC, posted the picture of a different woman on his Facebook wall at 10.30am.

“We had no idea a woman by that name existed and that she was pregnant. What we know is that the picture Kelvin posted belongs to one of his friends. He was not dating her,” said a friend who requested anonymity.

OFFLINE

“We chatted at 2pm. He said we would meet the next day as he was going to see his girlfriend. Then he went offline.”

The body was taken to Chiromo Mortuary. Mr Koome said the woman would be arraigned for murder on Friday.

The landlord said Kelvin was stabbed while in the house and as he got out, probably with the intention of seeking help, fell at the doorstep and died.

Incidents of couples fatally stabbing one another have been on the rise in the city.
