The Investigative Arm of the National Park Service
The special agents of the National Park Service Investigative Services Branch (ISB) are a specialized and highly trained team of criminal investigators. Together with program and victim support specialists as well as an intelligence analyst, the team works year-round and around the clock to investigate complex, sensitive, and long-term cases for crimes throughout the national park system. ISB personnel are stationed among America's more than 420 national parks and report directly to NPS headquarters in Washington, D.C.
