Defense to Seek New Trial in Chandra Levy Case Lawyers for the man convicted of killing Washington intern Chandra Levy say his prosecution was "predicated on a lie," and they intend to file a motion for a new trial. The arguments from attorneys for Ingmar Guandique (gwahn-DEE'-kay) were included in records of previously closed hearings in the case that were unsealed Tuesday. Levy was an intern for the U.S. Bureau of Prisons whose 2001 murder attracted attention because of her romantic relationship with a California congressman. Guandique is an illegal immigrant from El Salvador and was convicted in 2010. He is serving a 60-year prison sentence. The case hinged on a jailhouse informant who said Guandique had confessed to killing Levy. The documents show prosecutors learned a year ago about a problem with a witness but it's not clear if that person was the informant.
