The Virginia Court of Appeals on Tuesday exonerated a man convicted in a series of sexual assaults in 1984. DNA evidence showed that the man, Thomas Haynesworth, could not have committed the crimes in which such evidence had been preserved, and it pointed to another man. Gov. Bob McDonnell released Mr. Haynesworth on parole in March, but Mr. Haynesworth petitioned for full exoneration. Prosecutors in the counties where the assaults occurred supported his effort, as did the commonwealth’s attorney general, Kenneth T. Cuccinelli. The Court of Appeals initially heard the appeal and then asked for further briefs. Shawn Armbrust, executive director of the Mid-Atlantic Innocence Project, said, “After serving nearly 27 years for crimes that he didn’t commit, Mr. Haynesworth has had to register as a sex offender and abide by degrading conditions while the Court of Appeals took nearly nine months to conclude that the attorney general and the prosecutors were right that Mr. Haynesworth didn’t commit these crimes.”
