The judgment in Malindi marks the first time Mackenzie will face a verdict on the most serious charges of murder. Authorities have said over 400 bodies were found in shallow graves in the Shakahola forest near the Kenyan coast, where Mackenzie led his followers after shutting down his main church in 2019.
Seventeen men from a nearby town were hired to dig up the graves, some paid about $8 a day. James, one of the gravediggers, told the BBC: "Every grave we found had at least three bodies. Some of the remains were of children as young as a few weeks old. We once found 12 bodies of children in a line inside a grave. It was massive, the bodies were arranged like clothes. One on top of another."
Mackenzie established Good News International Ministries in 2003, growing a following of thousands through branches across Kenya and a television station called Times TV. His sermons included conspiracy theories labelling education as evil, healthcare as against doctrine, and digital ID cards as the mark of the devil.
Stephen Mwiti, 48, lost all six of his children to the cult. Speaking to the BBC, he said: "If I met Pastor Mackenzie today, one of us will have to die." His former wife is among those accused alongside Mackenzie.
Peter Shukrani, 23, attended Mackenzie's church from age eight and described him as his "spiritual father". Rescued from the forest in March 2023, Shukrani said his mother threw away medicine because of the doctrine. Despite nearly dying, he told the BBC: "Mackenzie didn't force anyone to fast. People made those choices by themselves because of their beliefs. I still love him and he is still my pastor."
Mackenzie's son, Dan Paul Mackenzie, who worked as a cameraperson for the church, took a different view. "He was the leader, he was someone who they were looking [up to]. So he is a murderer of mass killing," he said.
The 298-page charge sheet lists all 191 victims as children. Many bodies remain unidentified due to advanced decomposition. Mackenzie and his co-accused also face additional cases for terrorism, radicalisation, and denying children education.
Mackenzie's former head of security, Enos Amanya Ngala, initially accused in the case, entered a plea deal and became a prosecution witness.
