Tabitha Koech surrendered herself to the Bomet Police Station with a blood-stained knife. She confessed that she had killed her boyfriend, Kevin Kiptoo, 22, at Kapkwen market on Wednesday.
According to Standard Media, the reason as to why Ms Koech killed him is because she was suspecting he cheated. The police recorded the crime in the Occurrence Book but they are yet to take her statement since she is emotionally unstable.
Detectives have been sent to the market to investigate whether the girl killed the boyfriend alone or planned to do it with friends. The body was taken to Longisa County Hospital mortuary awaiting a post-mortem examination.
