A Rockford man who spent more than 13 years in prison for a murder he didn't commit has been formally declared innocent of the 1993 killing of a college student. Alan Beaman's conviction was reversed in 2008 after DNA testing excluded him as the killer of Illinois State University student Jennifer Lockmiller. Thursday's court declaration of his innocence allows Beaman to formally clear his name. He's also suing police and prosecutors for violating his civil rights. No other suspects have been charged.
