Madison police have identified the man taken into custody after he reportedly fired a gun on the porch of a Williamson Street residence Monday as Forest Shomberg, who spent six years in prison for a sexual assault a judge determined he didn?t commit. Shomberg was released from prison in November 2009 after the Wisconsin Innocence Project presented DNA and other evidence that raised doubt about his conviction for a March 8, 2002, incident in which a UW-Madison student was pulled from State Street and violently groped.
