How to make an evidence board

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 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]

Evidence boards are associated in fiction with both detective activities and obsessional interests, including those of delusional individuals pursuing conspiracy theories.[citation needed]

Evidence boards can be seen in numerous TV series, including Homeland, Fargo, Sherlock, The Bridge and True Detective.[5][3]

Evidence boards have also been used as a teaching tool.[6]

Use of the Anacapa charting system, as developed by Anacapa Sciences Inc., Santa Barbara, California 2, is currently the predominant form of network analysis within law enforcement. It is used particularly frequently within major fraud investigations and by Organized Crime Squads, where understanding of large and sometimes sophisticated criminal enterprises is required. Anacapa charts constitute a two-dimensional visual representation of link data (see Harper and Harris, 1975; Howlett, 1980; Klovdahl, 1981; Coady 1985). They provide a method of making visual sense of a mass of data. They are also an extremely useful tool for communicating the results of analysis (and thus are used as briefing aids as well as aids for analysis). Anacapa charts generally depict individuals by small circles, and relationships by lines (solid or dotted according to whether the relationship is confirmed or unconfirmed). The charts may also show rectangles enclosing one or more individuals as a method of representing membership of corporations or institutions. They clearly show who is central, who is peripheral, and visually reveal chains of links connecting one individual to another. To a network analyst they look like typical network diagrams.

In order to build your case and make a good decision, it’s important to start with a general overall Evidence Board.  To begin, make a list of pros and cons.  These pros and cons should be made up of any general idea you see that’s connected with the drama you face.  Remember that your #1 enemy is yourself.  Force yourself to look at all the clues; not just the ones you prefer to see.  (see resources for a picture of a detailed chart)

Imagine that you have just walked into a crime scene.  Of course, we don’t think your drama is a crime, but but for discussion ease…let’s view the situation as a mystery, a crime scene, a puzzle.  The first thing you should do in this investigation is to take a look around the room and make a note of the “general” information. 

What time of day is it?

How many people are in the room (or situation)?

Are they happy or sad?

Does the room (situation) look as if there’s been a fight with furniture or items out of place?

Are there any unusual sights, sounds, smells or uneven feelings in the room (situation)?

In other words, take stock of the room and your first impressions.  As you look at the situation you are investigating, include any pertinent information on your Evidence Board.  I place this type of information to the side so that I can pull it into my Decoder Map when necessary. 

Once you have a full Evidence Board and you have investigated all the general information, it’s time to move on to the Decoder Map.  Let’s use the example of a 9 year old child that has just received three F’s on his report card.  How should you handle that situation?  Your Evidence Board should look like the following:

Evidence Board

  • Crying

  • Sad

  • pouting

  • hungry

  • nose running

  • baseball glove thrown in hallway

  • crumpled report card

  • shredded homework

  • books open and scattered on desk

  • red letters on notebook “I’m dumb”

  • a towel covers the face of his portable TV

  • the computer monitor has been turned away from his desk

  • a mustache and horns have been drawn on a girl’s picture

All of these general clues must be considered when determining the “real” cause of his bad grades.  Any plan we design at this point would probably not be successful.  Even though some clues look suspicious, we do not have enough information to draw a conclusion.  The next step would be to begin our Decoder Map and see how much of our original evidence can be supported and connected.

Until you practice how to use this form to make good decisions, I suggest that you grab a piece of paper and do this manually.  Eventually you will get the hang of seeing all the clues in your head.  At that point you may venture to make decisions without physically writing all the clues down.  FYI – even after years of doing this in my head, some problems are so complicated and difficult that I still pull out pen and paper and plug my thoughts into an Evidence Board and Decoder Map.
