The death of a potential International Criminal Court (ICC) witness who was a teacher at a school in Kakamega is shrouded in mystery, with human rights activists piling pressure on authorities to unravel it.
Christopher Koech, who taught at Khaunga Primary School in Mumias, died under unclear circumstances on Sunday after he was admitted to Kakamega County Referral Hospital when he became suddenly ill.
He was reported to have gone to school on his motorbike on Saturday and spent about an hour there before he left hurriedly for an undisclosed destination.
He was later found lying on the side of a road next to his motorbike near Shibuli market.
He had foam in his mouth and was sweating profusely, raising suspicions of poisoning.
Shibuli lies on the Mumias-Kakamega road, some 21km from the primary school.
The teacher was said to have been agitated and engaged in a brief struggle with traffic police officers who blocked him from riding the motorbike as his condition looked serious.
His death has left his colleagues in shock and disbelief.
