In February 1971 all the media was abuzz with rumors that one of the astronauts on the Apollo 14 mission was conducting a Moon-to-Earth ESP experiment with a psychic-sensitive somewhere on Earth. On February 26, Life magazine was revealed that Chicago-based Olof Jonsson was the psychic who had been chosen to participate with astronaut Edgar Mitchell in the experiment. Jonsson was considered the most tested, tried, laboratory-evaluated psychic-sensitive in the United States and Scandinavia.
In March 1952, Jonsson's psychic detective work led to a murderer responsible for the deaths of 13 victims. In each instance, the man attempted to destroy evidence by torching the home of his victim. The murderer turned out to be the police officer assigned to work closely with Jonsson on the investigation. When the officer realized the investigation was directed toward him, he committed suicide.
Jonsson came to the United States in 1953 to be investigated by the well-known parapsychologist Dr. J. B. Rhine. For the next 14 years Jonsson submitted to testing at various ESP testing laboratories. He would sit guessing Zener cards—the classic testing deck consisting of the symbols cross, square, wavy line, circle, and star—by the hundreds or the thousands.
In 1978, Olof Jonsson joined a crew of 11 treasure hunters, including President Ferdinand Marcos (1917–1989) of the Philippines, to locate the gold that had been plundered by Japanese officers during World War II and hidden on the islands. Jonsson was instrumental in locating several mineshafts containing more than $2 billion in gold. Jonsson and a number of the other treasure hunters recalled later how the mine shafts were filled with the sorrowful spirits of the men and women the Japanese military had enslaved to do the digging.
Throughout the 1970s and 1980s, Jonsson joined numerous treasure hunters who sought the watery graves of ships that had gone down with cargo on board. Although he continued to be successful in these quests, Jonsson received little income from these enterprises.
