In November 2018, John Allen Chau, a 26-year-old US missionary trained and sent by Missouri-based All Nations, was killed during an illegal trip to the restricted island, planning to preach Christianity to the Sentinelese. Seven individuals were taken into custody by Indian police on suspicion of abetting Chau's illegal access to the island. Entering a radius of around the island is illegal under Indian law. Fishermen told police that they had seen the tribespeople dragging Chau's body around but the authorities had not been able to independently verify his death as of 25 November 2018. The case is being treated as a murder but there has been no suggestion that the tribesmen would be charged.
