James Riley was a veterinarian.
Riley got a call from and then soon a visit from Ian Detweiler who wanted a tranquilizer drug. Riley obliged and gave him a substitute. Unbeknownst to Riley, Detweiler was using it to suppress his wanshang dhole form. When Riley was locking up later, he saw Detweiler in his animal form and escaped, calling the police. Officer Jeffrey Cahn arrived and made a shot in the dark, seemingly shooting the wrong dog. It was actually Detweiler in a different dog form, which Riley then operated on and fixed. Once finished and alone, Detweiler turned into his wanshang dhole form and killed Riley. (TXF: "Alpha")
