She stabbed him in the neck and chest.
A 19-year-old woman who stabbed her boyfriend to death over a phone dispute was lynched by a mob in Murang’a County on Thursday morning.
Mr Kennedy Murimi, 23, is said to have been stabbed twice in the neck and chest by his girlfriend Ms Salome Wambui after he asked for her phone and allegedly refused to return it to her.
Ms Wambui was later beaten and set on fire by an angry mob at Mr Murimi's home area in Wairi Village, Kangema Constituency.
His mother Flasia Nyambura Kariuki said Ms Wambui had spent the night with Mr Murimi's female cousin and had claimed that she had come with a knife which she would use to kill him.
"She came to my son's house in the morning and walked out, but a few minutes later we heard a loud scream. We found my son lying on the floor," Mrs Kariuki said, adding that he bled and died on the spot.
Mr Murimi, a saw miller, was the last born in a family of seven and he helped his parents financially.
An eye witness told the Nation that Ms Wambui was questioned by the public, but she became rude and even threatened to kill whoever would approach her.
"That's how members of public got furious and started beating Ms Wambui and later lynched her," Mr James Mwaura said.
Kangema OCPD Cosmas Wachang'oka said his officers rushed to the scene after Mr Murimi's father reported his death.
He said the officers found two bodies – Mr Murimi’s and Ms Wambui’s.
"Ms Wambui's body was burnt. We took their bodies to Murang'a Morgue," the police boss said.
He urged residents not to engage in love affairs when they are young, as they do not know how to solve relationship problems.
Mr Wachang'oka said they have launched investigations into the two killings.
