Yamashita himself was convicted of war crimes and executed by the United States Army on February 23, 1946, in Los Baños, Laguna, the Philippines.
[5][b] Sterling Seagrave alleged that Santa Romana (Santy) tortured Yamashita's driver Major Kojima Kashii to obtain the probable locations of the loot.
[6] Ray Cline believes that both Robert Anderson and Paul Helliwell created 176 "black gold" banking accounts in 42 countries after moving the loot by ship to support future United States operations.
[citation needed][c] The stolen property reportedly included many different kinds of valuables looted from banks, depositories, other commercial premises, museums, private homes, and religious buildings.
As the War in the Pacific progressed, United States Navy submarines and Allied warplanes inflicted increasingly heavy sinkings of Japanese merchant shipping.
"[16] Philippines National Historical Institute chairman and historian Ambeth Ocampo commented: "Two of the wealth myths I usually encounter are the Yamashita treasure and gossip that the Cojuangco fortune was founded on a bag of money..." Ocampo also said: "For the past 50 years, many people, both Filipinos and foreigners, have spent their time, money and energy in search of Yamashita's elusive treasure."
Professor Ocampo noted "What makes me wonder is that for the past 50 years, despite all the treasure hunters, their maps, oral testimony and sophisticated metal detectors, nobody has found a thing."
Roxas claimed that within the next few years he formed a group to search for the treasure, and obtained a permit for the purpose from a relative of Ferdinand, Judge Pio Marcos.
In 1971, Roxas claimed, he and his group uncovered an enclosed chamber on state lands near Baguio where he found bayonets, samurai swords, radios, and skeletal remains dressed in a Japanese military uniform.
Two individuals representing prospective buyers examined and tested the metal in the Buddha, Roxas said, and reported it was made of solid, 20-carat gold.
[18] In 1998, the Hawaii Supreme Court held that there was sufficient evidence to support the jury's finding that Roxas found the treasure and that Marcos converted it.
