Over 30 days after second-year UVA student and West Potomac alumna Hannah Graham was last seen on a surveillance tape in Charlottesville’s Downtown Mall, Charlottesville police and the Virginia Department of Emergency Management are continuing their search.

Graham’s parents John and Sue made a statement via the UVA website on Oct. 13, marking the one-month mark, urging people to speak up, or search their own property if they haven’t already.

“We truly appreciate the enormous effort that is being made to find Hannah,” they said. “It is heart-breaking for us that the person or persons who know where Hannah is have not come forward with that information. It is within their power both to end this nightmare for all, and to relieve the searchers of their arduous task.”
