Kevin Martin has been out of prison for five years now, after spending 26 years behind bars for a 1982 D.C. killing he did not commit. But Monday was a special day for Martin, 50, who was declared “actually innocent” by a Superior Court judge on the basis of recent DNA testing. Still, Martin’s exoneration remains part of a larger tragedy in which faulty FBI hair analysis put at least four other men behind bars for D.C. crimes they did not commit. U.S. Attorney Ronald C. Machen Jr. continues to examine old cases for similar evidence issues, The Washington Post’s Keith Alexander and Spencer Hsu report, and while the D.C. review is winding down, a national review is also underway — meaning many more Kevin Martins might be out there. More from WTTG-TV’s Paul Wagner.
