Migori County governor Okoth Obado confessed to an affair with 26-year-old university student Sharon Otieno, whose body was found in a thicket in Homa Bay on Tuesday last week.
He also told detectives that he planned to buy Ms Otieno a house. He did not explicitly say the baby Ms Sharon was carrying was his, but he did not deny it either.
Mr Obado showed detectives a series of chats and text messages between him and his girlfriend as he fought to delink himself from her murder.
He laboured to prove that his relationship with Ms Otieno was romantic to the end, and therefore he could not have been involved in her abduction, torture, and murder.
Detectives from the Directorate of Criminal Investigations’ Homicide Investigations Unit, Serious Crimes Unit, Special Crimes Prevention Unit and the Cybercrime Investigations Unit have been trying to piece together the murder jigsaw puzzle by taking statements from witnesses, the suspects arrested so far, Nation journalist Barrack Oduor, and the Governor and some of his close associates.
They have also been analysing text messages and calls from the persons of interest in their quest to find the killers of the university student, who was murdered while seven months pregnant.
First, police sources said, he indicated that he and Sharon engaged in run-of-the-mill love and romantic messaging, both on WhatsApp and SMS.
The messages included plans for travel, where to meet, certain items the Governor was to buy, as well as discussions on the future of the baby Ms Otieno was carrying.
Detectives also learnt that Mr Obado, 59, had discussed the possibility of getting a house for the woman, even though the chats also indicated that they had not agreed on where to buy or build it.
