The guy was probably innocent. He may have been a stranger in the area hence the reason Matiangi says he is still unknown. Such horror happened a to neighbor of mine who had ventured into Kisii land for greener pastures some few years ago. Alikatakatwa na villagers same style.
This is something that has been happening. That's why the onlookers are unmoved by the heinous act. Someone had the audacity even to record the whole gory event.
