Isaiah Murangiri, a police officer suspected of fatally shooting 29-year-old Rex Masai during the June 18, 2024 protests in Nairobi, has denied any involvement in the killing. Despite video footage and phone data showing Murangiri at the scene and on Uhuru Highway, he maintains he was not the armed officer responsible. During the inquest into Rex Masai's death, Tiberius Ekisa, the former Deputy County Inspector of Police (DCIO) for Nairobi Central, testified that he neither knows Murangiri nor gave him any orders related to the shooting. Ekisa stated that Murangiri was not under his command and emphasized that no bullets were recovered in connection to the incident. Murangiri remains the primary suspect in the case, which continues to draw attention amid conflicting evidence and testimonies.
