The Lignarius in Charleston

One of her hands went up to her forehead.  The IV stuck in her forearm pulled against the tape holding it in. He noticed bruises there, too. Big welts in purple and gross red.

                 “So, miss? What can you tell me?”
                 “Not much.  We went for a walk down at the Battery.  By the seawall.”  She finished speaking, her voice slurred slightly, or maybe that was her accent he was hearing. 
                 “I saw that earlier today.”
                   After taking a deep breath, Natalie blinked away tears and continued, each word coming out slowly. “It was late; I just started walking back to campus because I had a book to finish reading. Earl, my friend, stayed behind, it was dark and even with the street lights, there were shadows moving. The trees, the leaves moving in a breeze…things looked as if they were moving but it was just shadows.”
                   Jim nodded, hoping she would get to the point. “So, what happened then? A noise, a chill perhaps?”
                     A huge tear ran down her cheek. She wiped it away and swallowed audibly. “They came at him. There was a rush of motion, barking, screaming…Earl yelled ‘Run! Run!’…and I did. I looked back, saw…saw dogs…lots of dogs…they brought him down. He screamed, I started back toward him, one of the dogs, a pit bull, I think, looked directly at me and I took off.  I ran….”
                     Dogs?  Could this be a feral pack?  Not a vampire at all?
