"I DON'T WANT TO DIE," he wrote last week in a note left with the fishermen who brought him to the island, according to The Associated Press. "Would it be wiser to leave and let someone else to continue. No I don't think so."
The next day, Chau returned to the island. He never returned to the fishing boat. One of his fellow missionaries wrote in an email to Chau's mother that fishermen saw the tribe burying Chau's body on the beach, according to the Post.
Indian law protects North Sentinel, which is off-limits to visitors, and its isolated inhabitants. Since Chau's death, seven people believed to have helped him reach the island have been arrested and charged with culpable homicide not amounting to murder and with violating rules protecting aboriginal tribes, the Times reported.
Members of Chau’s family said in statement posted Thursday to Instagram that they forgive the people responsible for his death and asked that charges against the seven be dropped.
“He ventured out on his own free will and his local contacts need not be persecuted for his own actions,” the statement said. “He loved God, life, helping those in need, and had nothing but love for the Sentinelese people.”
Scholars know almost nothing about the island, from how many people live there to what language they speak. The Andamans once had other similar groups, long-ago migrants from Africa and Southeast Asia who settled in the island chain, but their numbers have dwindled dramatically over the past century as a result of disease, intermarriage and migration.
The Sentinelese killed a pair of Indian fishermen who accidentally washed up on the island in 2006, according to the Times. In the 1970s, a National Geographic documentary director was shot in the leg with an arrow on the island, the newspaper reported.
