Lawyers for 75-year-old William Barnes said Thursday that Pennsylvania's parole board has granted Barnes' parole. It's not clear when exactly he will be released.
Barnes has been incarcerated since Officer Walter Barclay died in 2007. Prosecutors said Barclay's death was directly caused by Barnes' shooting and paralyzing him 41 years earlier.
Barnes served his full sentence for shooting Barclay. In 2010, a jury acquitted him of murdering Barclay, but he's still in prison.
The District Attorney's Office declined to comment.
