(CNN) A Kenyan governor has been charged with aiding and abetting the murder of a pregnant student with whom, prosecutors say, he was in an "intimate relationship."

Gov. Okoth Obado of Migori County in western Kenya is accused of killing Sharon Otieno, 26, who was abducted September 3 alongside local journalist Barack Oduor.

Oduor escaped and reported the incident to police, prosecutors say.

Two days later, Otieno, who was seven months pregnant, was found by the roadside, covered in stab wounds. Her unborn baby also had stab wounds, according to local media reports

A media statement from Kenya's Director of Public Prosecutions, Noodin Haji, said: "Sharon and her unborn baby lost their lives in a gruesome and horrifying manner in the hands of her killers. My office is therefore committed to ensuring that all the perpetrators of the heinous act are brought to book and subjected to the due process of the law."
