An 88-year-old former boxer, Iwao Hakamada, was acquitted by a Japanese court after a retrial for a 1966 quadruple murder, reversing his status as the world’s longest-serving death row inmate. The Shizuoka District Court found evidence was fabricated by investigators. Hakamada’s acquittal, the fifth in postwar Japan, may spark debate on the death penalty. His 91-year-old sister celebrated the ruling after a 58-year legal battle. Hakamada spent 48 years in prison, mostly on death row. Prosecutors have not decided whether to appeal, and the defense may sue the government for the flawed investigation.
