This map follows each piece of evidence tied to Derik Brown from the agency that first held it to every agency it went to after. Each row is an agency. Each colored line is one piece of evidence, moving left to right in date order. A solid dot is a handoff a document shows. A dashed red ring is a step the record shows happened, but whose paperwork is not found in the discovery materials available to us. Not found is not the same as never existed; see Missing Records.
