The Katuic peoples live mainly in central Vietnam's Truong Son region and the highlands of south eastern Laos. The peoples include the Katu, Ta Oi, Pacoh, Bru (Van Kieu) in Vietnam and the Kuy. The Katuic groups in Laos include the Kuy, Bru, Ta'oih, Kantu, Dakkang, Triw, Chatong and Ngeq. The French military officer Le Pichon, who was stationed among the Katu in 1938, wrote a short book about entitled Les Chasseurs de Sang (The Blood Hunters) about the (now non-existent) practice of the Katu to hunt people to please certain spirits.
