Wanted notices
All wanted notices containing fingerprints, including the wanted notices inserted in the FBI Law Enforcement Bulletin, should be filed in the fingerprint file by classification formula, and the names appearing on these wanted notices should be indexed and placed in the name files. Concerning the small wanted notices inserted in the FBI Law Enforcement Bulletin, a suggested procedure would be to paste each individual notice on a blank 8- by 8-inch white card. The wanted notices are filed by the fingerprint classification and the names indexed and placed in the name file. When an apprehension notice is received concerning the wanted notice, a proper notation should be made on the name card and the wanted notice in the fingerprint file. If these canceled wanted notices endanger the efficiency of the file, it is suggested that the name-index card and the fingerprint-wanted notice be destroyed. Should the bureau adopt this practice it is suggested that the 8- by 8-inch cards be used again for other wanted notices. In this manner it would be possible to use the blank card for eight of these notices.
The Federal Bureau of Investigation will make available to law enforcement agencies a special "Wanted Notice" form (No. 1-12) in order that they can place wanted notices against the fingerprints in the files of the FBI.
Photographs
Arrangements should be made to procure a camera for taking photographs of the persons fingerprinted. This is known as a "mugging" camera and various types are on the market. It is believed that the photographs should include a front and side view of the person. In most instances a scale for indicating height can be made a part of the picture even though only the upper portion of the individual photographed is taken. Of course, if the scale is used, the person photographed should be standing even though only the upper portion of the body appears in the photograph. The necessary lights should be provided for obtaining photographs. A standard set of scales should be obtained in order that the correct weight can be ascertained.
The negatives and photographs can be filed by fingerprint number in a separate file. In those cases where the individual has more than one arrest all the photographs can be placed in the jacket-folder number file. The negatives, in these instances, can remain in the photograph file.
Latent fingerprints
To adequately develop the latent prints at crime scenes, it is necessary that the proper equipment be provided. This equipment includes latent fingerprint powders, brushes, lifting tape, fingerprint camera, searchlight, and scissors. All of this equipment can be obtained from commercial fingerprint supply companies. Figure 419 shows some of the equipment used by the FBI. The techniques of developing latent fingerprints and their uses are more fully explained in the following chapters.
