After more than four decades spent alone in a cell measuring six feet by nine feet, Albert Woodfox walked free on Friday, his 69th birthday.

A federal appeals court ruled on Monday that Louisiana may retry Albert Woodfox, the last member of the “Angola 3” still incarcerated, who a lower court ordered freed in June, The Advocate reports. Woodfox has been in solitary confinement for nearly all of the past 43 years.
