FBI Correspondence Regarding Animal and Cattle Mutilations (1974-1976)

This collection of documents chronicles the Federal Bureau of Investigation's (FBI) response to a wave of livestock mutilations reported across several U.S. states between 1974 and 1976. The records consist primarily of correspondence between FBI Director Clarence M. Kelley and U.S. Senators Carl T. Curtis and Floyd K. Haskell, alongside internal memoranda from various field offices, including Denver, Minneapolis, and Springfield. The incidents, which involved cattle found with specific organs removed—such as ears, eyes, lips, and sexual organs—and reports of blood being drained, generated significant public concern and media attention. Senators Curtis and Haskell repeatedly urged the FBI to intervene, citing the widespread nature of the events and the potential for interstate criminal activity. However, the FBI consistently maintained that it lacked investigative jurisdiction. The Bureau argued that there was no evidence of federal law violations, such as the interstate transportation of stolen cattle, and that the matter fell under the purview of local law enforcement and state agencies. Internally, the FBI sought expert opinions to explain the phenomenon. Dr. Don Wilson of the U.S. Fish and Wildlife Service suggested that the mutilations were consistent with natural predation by small mammals like foxes and opossums, which often target soft tissues on carcasses. Despite pressure from political figures and the press, the FBI remained firm in its refusal to initiate a federal investigation, fearing that doing so would overstep its statutory authority and lead to the perception of the FBI as a national police force. The documents reflect a tension between public demand for federal action on mysterious phenomena and the Bureau's strict adherence to its defined jurisdictional boundaries.
