Investigation Ordered in Killing of Chut Wutty in Cambodia Prime Minister Hun Sen has ordered an investigation into the death of a prominent environmentalist during a confrontation with military police. The environmentalist, Chut Wutty, was killed Thursday as he accompanied two journalists investigating illegal logging in a protected forest. The police said an officer shot Mr. Chut Wutty and then killed himself. The prime minister's order, issued Monday, followed calls by rights groups for an investigation.
