Police officers in Kawethei in Kangundo, Machakos County, are investigating the death of Charles Kituku Muthusi of Mukunike.
The man belongs to AIC church, police said.
The preacher’s body was reportedly discovered early Tuesday morning and dumped in a maize plantation, some 50 meters away from his house.
The motive of the murder is yet to be known.
The body had head injuries, and the eyes had been gouged out.
Officers from the Kawethei police post who arrived at the scene collected several pieces of rock that appeared to have been used to kill the preacher.
Police also recovered a screwdriver near the scene believed to have been part of the murder weapon.
His brother, Reverend Peter Muthusi, expressed his shock at the cold-hearted murder, saying their other brother had met a similar fate in Nairobi a while back.
The body was moved to the Kangundo Level 4 Hospital pending investigations.
