Oyamo, key suspect in Sharon’s murder was Governor Obado's student

Michael Juma Oyamo, the key suspect in the murder of university student Sharon Otieno, was once Migori Governor Okoth Obado's student at St Joseph's Rapogi High School.

Mr Obado, also an alumnus of Rapogi High in Uriri, Migori County, was posted to the school in the mid '90s after graduating with a bachelor's degree in education from Kenyatta University.

Mr Oyamo, who would become the governor's personal assistant 22 years later, has been described as one of Obado's favourite physics and accounting students.
