John Sharkey of "The Washington Post" found records that Marcos was in the list of those that were released due to either "having severe health problems and those whose families have cooperated with the Japanese military authorities." Since Marcos's name did not appear in the 1942 "Manila Tribune" list of ailing prisoners that were released by the Japanese, Sharkey believed that Marcos may have been freed due to his connections with his father. Mariano Marcos was known to have collaborated with Japanese authorities, and at the end of the war was caught by Filipino guerillas and was tied to four water buffalos and was quartered. His remains were also displayed in public by the guerillas.
