John Chau, 26, was allegedly killed on Nov. 17 by people of the Sentinelese tribe who inhabit the North Sentinel Island in the Andaman and Nicobar island chain. Chau’s family said in a social media post he was a Christian missionary and mountaineer. Police are now investigating if Chau had help from other people to travel to North Sentinel, Vijay Singh, senior superintendent of police (SSP) in the Andaman and Nicobar islands, said in a statement.
