CHARLOTTESVILLE, Va. (AP) _ Authorities in Virginia have scheduled a news conference to provide an update in the case of a man linked to two college students who disappeared and were later found dead. The briefing by Albemarle County’s police chief and its prosecutor is set for 11 a.m. Tuesday. Officials said in their announcement that they will not answer questions before the press conference. Jesse Matthew Jr. is charged with abduction with intent to defile in the case of University of Virginia student Hannah Graham. The 18-year-old Graham disappeared in September and was found dead in Albemarle County a few weeks later. Police have said forensic evidence also links Matthew to the 2009 disappearance and death of Virginia Tech student Morgan Harrington, whose body also was found in the county.
