Mai Mai rebels are described as community-based militia groups frequently involved in banditry. Another ranger was wounded in the attack and a rebel was captured. That arrest has resulted in several leads in the investigation.
"The Mai Mai are seeking to wear down the rangers because they don't want the park to exist. They want to cultivate and poach in the park," said Samantha Newport, communications director for the refuge.
The ranger's name was Safari Kakule, and he was called "exceptional." Here is a brief Youtube video of him. He left a wife and three children.
