The criminal defense lawyers representing three men charged in connection to the murder of Washington attorney Robert Wone are fighting to block federal prosecutors from arguing at trial that Wone was restrained, drugged, sexually assaulted and tortured.

Defense lawyers Thomas Connolly, Bernard Grimm and Robert Spagnoletti said in court papers filed Feb. 26 in D.C. Superior Court that the government should not be allowed to introduce evidence of uncharged misconduct that the defense attorneys call “grossly prejudicial.” A hearing is scheduled for March 12, and trial is set for May.
