Computer guru and plant operator: Experts who enforced Mackenzie’s evil plan jailed for 160 years

One was trained in computer programming and had worked in the hotel industry, while the other operated heavy machinery and was involved in major infrastructure projects, including the Standard Gauge Railway.

Yet their professional lives took a dramatic turn when both became key figures in Paul Mackenzie's religious movement, eventually emerging as enforcers in the deadly Shakahola settlement.

Smart Deri Mwakalama, Mackenzie's deputy and logistics chief, and Steven Sanga Muye, the settlement's head of security, will each serve 160 years in prison for their roles in the murder of 191 people, including 190 children, in Shakahola Forest.
