The alert gets officers to the scene. The Investigative Lead Summary (ILS) and Detailed Forensic Report (DFR) get the case to court. The ILS surfaces investigative intelligence quickly, helping detectives build a timeline and identify leads in the early hours of an investigation. The DFR goes deeper, providing verified acoustic data, round count, firing sequence, and technical documentation precise enough to embed directly into a search warrant application. When Lancaster brought that documentation before a judge who had never encountered gunshot detection evidence, the report explained the technology so thoroughly that prosecutors didn't have to. If your agency is not pulling ILS and requesting DFR reports on significant incidents, you are leaving your investigators and prosecutors without their strongest tools. This video is part of a series on how Lancaster PD built a ShotSpotter deployment that delivers value from first response through final verdict.
