Michael Rockefeller disappeared in New Guinea

Michael Rockefeller

Michael C. Rockefeller (born 1938 - died November 18, 1961?), was a member of the Rockefeller family and youngest son of Governor Nelson Rockefeller who disappeared during an expedition in the Asmat region of southwestern New Guinea.
Rockefeller graduated from Harvard University cum laude in 1960, served for six months as a private in the U.S. Army, then went on an expedition for Harvard's Peabody Museum of Archaeology and Ethnology which studied the Dani tribe of western New Guinea. The expedition produced "Dead Birds", a renowned ethnographic documentary film produced by Robert Gardner, and for which Rockefeller was the sound recordist. Rockefeller and a friend briefly left the expedition to study the Asmat tribe of southern New Guinea. After returning home with the Peabody expedition, Rockefeller returned to New Guinea to study the Asmat and collect Asmat art.
"It's the desire to do something adventurous," he explained, "at a time when frontiers, in the real sense of the word, are disappearing."
On November 18, 1961, Rockefeller and Dutch anthropologist René Wassing were in a 40-foot dugout canoe about three miles from shore when their double pontoon boat was swamped and overturned. Their two local guides swam for help, but it was slow in coming. After drifting for some time, Rockefeller said to Wassing "I think I can make it" and swam for shore. Wassing was rescued the next day, while Rockefeller was never seen again, despite an intensive and lengthy search effort. At the time, Rockefeller's disappearance was a major world news item. No body was found, and he was finally declared dead in 1964.
Most believe that Rockefeller either drowned or was attacked by a shark or crocodile. Because headhunting and cannibalism were still present in some areas of Asmat in 1961, some have speculated that Rockefeller was killed and eaten by local people. Reports have surfaced of a white man living with the natives, but this has no credibility to those who are familiar with the area.
In 1969, journalist Milt Machlin traveled to New Guinea to investigate Rockefeller's disappearance. He dismissed reports of Rockefeller's living as a captive or as a Kurtz-like figure in the jungle, but concluded that there was circumstantial evidence to support the idea that he was killed. Several leaders of Otsjanep village, where Rockefeller likely would have arrived had he made it to shore, were killed by a Dutch patrol in 1958. Neither cannibalism nor headhunting in Asmat were indiscriminate, but rather were part of a tit-for-tat revenge cycle, and so it is possible that Rockefeller found himself the inadvertent victim of such a cycle started by the Dutch patrol.
A book called "Rocky Goes West" by author Paul Toohey claims that, in 1979, Rockefeller's mother hired a private investigator to go to New Guinea and try to resolve the mystery of his disappearance. The reliability of the story has been questioned, but Toohey claims that the private investigator swapped a boat engine for the skulls of the three men that a tribe claimed were the only white men they had ever killed. The investigator returned to New York and handed these skulls to the family, convinced that one of them was the skull of Rockefeller. If this event did actually occur, the family has never commented on it.
Many of the Asmat artifacts Rockefeller collected are part of the Michael C. Rockefeller collection at the Metropolitan Museum of Art in New York City.
