Njoki's mother Whitney Kagiri, who described her as a bright and humble girl, said the school had linked her death to tonsillitis which the family does not agree with. "I saw my daughter's body at the hospital. She had bled through the nose and mouth. How is that related to tonsillitis?" posed Kagiri.

Njoro Sub-County Deputy Police Commander Lawrence Nallo, however, said the school told them that Njoki had fallen ill earlier this week and had visited the school clinic.

"The management says she had tonsillitis on February 7. She was treated at their clinic and she recovered. On Thursday at 10am, she was left in class as the rest of the students went for tea," said Nallo.

The police boss said the school principal ensured she visited the clinic but when her condition worsened, she was taken to the Njoro Sub County Hospital.

"What we know now is that she was taken to the hospital alive but in pain. She died as she was being attended to. The matter is under investigation," said Nallo.
