An evidence board (also known as a "conspiracy board," "crazy wall," or "murder map") is a common background feature in thriller and detective fiction movies and TV. [1] [2] It features a collage of media from different sources, pinned to a pinboard or stuck to a wall, and frequently interconnected with (usually red) string to mark connections. [3] A more technical related name for these sorts of visualizations and charts within law enforcement are Anacapa charts which are used for social network analysis. [4]
