Michael Clark Rockefeller (born 1938 - presumed dead November 17, 1961), was the youngest son of New York Governor (later Vice President) Nelson Aldrich Rockefeller and Mary Todhunter Rockefeller and a fourth generation member of the Rockefeller family. He disappeared during an expedition in the Asmat region of southwestern New Guinea.
On November 17, 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. His body was never found. He was declared legally 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.
In 1969, the 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, and thus would have some rationale for revenge against someone from the "white tribe." 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. There was, however, a report on the History Channel that Rockefeller's mother did pay a $250,000 reward to the investigator which was offered for final proof whether or not Michael Rockefeller was alive or dead.
