For Odhiambo's family, the day's outcome was devastating. His mother, Elizabeth Auma, stood at the edge of the site, her face etched with grief and disbelief.
"I am not satisfied at all. These sites looked disturbed, and I believe they moved the bodies. But what is hidden will be revealed. If they took my son's body from here and buried it elsewhere, we will find him," she vowed.
Brian's wife, Alvy Aoko, was equally distraught.
"Tomorrow marks exactly two months since my husband disappeared. We just want the truth. My children are suffering," she said.
Human rights activists and lawyers condemned the obstacles placed before investigators by the KWS management.
"This information came to light on Thursday. Since then, everyone has urged KWS to allow access to the site to verify whether the witness's claims were true," said Hussein Khalid, an official from Haki Africa, a human rights group.
His sentiments were echoed by family lawyer Mogendi Abuya, who revealed that on Thursday, KWS denied investigators and the family entry, citing the need for approval from a higher office.
