According to Kim

Shortly after Thursday night’s vigil the parents of Hannah Smith received a call from one of Hannah’s friends saying they were chatting on Facebook.  Hannah’s father sent her a friend request and they began to chat.  This has to be comforting for Mr. and Mrs. Smith, knowing that she is ok, but at the same time she is still not home.  They still do not know where Hannah is and will not be totally relieved until she is safely home.  Hopefully this Facebook chat is the beginning to a happy ending for Hannah and her family.
