Unexplained disappearances in U.S. national parks reveal a pattern: missing hikers vanish where search dogs fail, bodies appear in previously searched areas, and abduction accounts suggest non-human entities at work. Former law enforcement investigator David Paulides has documented over 1,500 cases with anomalous circumstances—no tracks, impossible locations, missing clothes—pointing to something beyond natural explanation. Search dogs with multiple handlers repeatedly fail to track missing persons in national parks, despite professional trainers and teams succeeding in nearly all other scenarios, suggesting missing people were not present during searches or were removed by non-standard means.
