Bloodthirst 2: Revenge of the Chupacabras (2005)

Detective Steve Andrews is investigating the disappearance of a pretty college co-ed when he gets a call that an inmate at the Hagerthy Psychiatric Hospital might know something about the case. The inmate, Charles Parker, has been telling the strange story of a vicious vampire-like beast called the Chupacabras that he claims he trapped in a nearby mine and destroyed after it had savagely killed a number of the local citizenry.
