Sharon Otieno was seven months pregnant and a student at Rongo University when she was abducted alongside Nation journalist Barrack Oduor.
On Wednesday, her lifeless body was found at Kodera Forest.
Her mother Melida Auma, who was overwhelmed, recalled to journalists how she had opposed her daughter's relationship with "a politician".
"I remember at her early stages of pregnancy, I asked her to tell us who was responsible for it and she told me it was Governor Obado. At one time she even said he had promised to buy her a house, take care of her pregnancy and the baby when it was born," Ms Auma said.
She went on: "Little did I know she would meet her death in such a brutal way."
Governor Obado's spokesman Nicholas Anyuor said the governor will not be drawn into the matter, "which is under police investigation, because he has not been implicated in it".
He will only comment if he is required to do so by the police, he added.
Sharon's grief-stricken father Douglas Otieno, who identified the body, spoke only briefly to the Nation.
Her body is at Rachuonyo Level IV Hospital in Oyugis, Homa Bay County where relatives and friends viewed it.
Reports indicated the body was found at Kodera Forest, but the Kenya Forest Service station manager Justus Kyambo said it was found some 15 kilometres away from the forest.
"Normally, police inform us whenever a body is found here but in this case, they didn't. We heard it was found about 15 kilometres from here," Mr Kyambo said.
BODY FOUND IN A THICKET
Homa Bay CID boss Daniel Wachira later said the body was picked from a thicket after "members of the public called police".
And in Migori, students of Rongo University staged demonstrations along Rongo-Migori-Sirare highway causing a huge tragic snarl-up.
The students demanded that police question Mr Obado over their colleague's death.
"We are demanding for the unconditional arrest of Governor Obado to explain what he knows about Sharon's death," said Peter Otieno, a student.
Merceline Nanjala added: "The arrest of the governor's right-hand man -- his personal assistant speaks volumes. The police must go for him and get down to the bottom of this matter."
Until her death, Sharon was a second year Medical records and information student at Rongo University.
