The parents of a missing University of Virginia student made a heartbreaking plea today.

It was one month ago today that UVA student Hannah Graham vanished. Jesse Matthew has been charged in her kidnapping, but Graham is still missing.

In a statement, her parents said, "It is now a month since our precious daughter Hannah disappeared [...] We truly appreciate the enormous effort that is being made to find Hannah. 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. Again, we would like to urge anyone who has not already searched their property in the city of Charlottesville, or any of the neighboring counties, to please do so today."

Her mother recently said in a video, “Somebody listening to me today either knows where Hannah is or knows someone who has that information. We appeal to you to come forward and tell us where Hannah can be found. Please, please, please help end this nightmare."

Courteney Stuart, of C-Ville Weekly, discussed the case on this evening’s “On The Record.” Watch more above.
