After the conduct of an autopsy, lead pathologist Bernard Midia said Albert Ojwang's injuries were externally inflicted and ruled out suicide.
"The pattern of the injury, especially on the trauma I found on the head, hitting against a blunt substance like a wall would have a pattern," Midia said, pointing out that Ojwang's injuries also showed signs of struggle.
Ojwang was arrested on June 7 and charged with "cyber harassment" after critical posts he made about Deputy Inspector General Eliud Lagat.
There have been growing concerns by local and international stakeholders about the government's handling of dissent.
