(Web Desk) - The world's longest-serving death row prisoner has been acquitted after a court in Japan ruled he wasn't behind a 1966 multiple murder.
Iwao Hakamada, 88, had spent 48 years behind bars, more than 45 of them on death row, longer than any other inmate.
The ex-boxer was sentenced to death in 1968 for killing his former boss, his wife, and two of their children and setting fire to their home.
He was acquitted on Thursday by a court in Shizuoka in central Japan, after the presiding judge, Koshi Kunii, said he wasn't guilty and evidence used against him had been made up, Japanese public broadcaster NHK said.
Hakamada originally denied being behind the murders, before confessing, which he later said he was forced to do after a violent interrogation by police.
Questions arose over blood-stained clothes investigators said belonged to him, which were found more than a year after his arrest, hidden in a tank of fermented soybean paste, or miso.
In 2023, a Tokyo High Court accepted evidence that clothing soaked in miso for more than a year turns too dark for bloodstains to be seen and admitted the evidence may have been concocted by investigators.
Furthermore, blood samples did not match Hakamada's DNA, and the trousers that prosecutors submitted as evidence were too small for him.
His planned execution was delayed by lengthy appeals and the retrial process, which meant he'd been in jail for 27 years by the time his first appeal for a retrial was turned down.
