The story of Iwao Hakamada, a former professional boxer and death-row inmate, 82, who continues to battle to clear his name over a 1966 quadruple murder, will be adapted into a manga series, supporters of the convict announced Wednesday.

Hakamada was sentenced to hang in 1968 by the Shizuoka District Court, but was freed in March 2014 after nearly 48 years in prison on death row. Much of that time was spent awaiting his retrial, which has yet to be held.

But a group of Hakamada's supporters who believe the former boxer is innocent want to retell the events in his case in the form of a manga, to convey his side of the story to younger generations.
