The Prince William Board of County Supervisors sued the Department of Homeland Security for records on the agencySSRqs handling of an illegal immigrant who was released by federal officials and later charged with drunken driving in a car crash that killed a nun. County officials argue that Homeland Security is unlawfully withholding records the Board of Supervisors requested about Carlos Martinelly-Montano, who Prince William County police turned over to Immigration and Customs Enforcement almost two years ago, according to a complaint filed in U.S. District Court on Tuesday.

ICE released Martinelly-Montano back into the community while he awaited his deportation hearing. He was charged in August 2010 with drunken driving in a fatal crash that killed one nun and left two others injured. He had two previous drunken-driving convictions.
