    1. 2. FBI MISSION STATEMENT The mission of the FBI is to protect and defend the United States against terrorist and foreign intelligence threats, to uphold and enforce the criminal laws of the United States, and to provide leadership and criminal justice services to federal, state, municipal, and international agencies and partners.

    5. 6. Federal Bureau of Investigation United States Department of Justice Illustrations of Various Fingerprint Patterns The presence or existence of whorls in finger impressions is used as the basis for the determination of the chief or the primary classification. Each whorl appearing in an or all of the ten fingers has a certain arbitrary or fixed value. The addition of the values represented by such whorls and the indication of the total value is known as the primary classification. Illustrations of the whorl types which are shown on the right of this chart. Illustrations of the other types are shown on the left.

    6. 7. FINGERPRINT PATTERN FREQUENCY
    7. 13. LOOP Definition: A LOOP is that type of pattern in which one or more ridges enter upon either side, recurve, touch or pass an imaginary line between delta and core and pass out or tend to pass out upon the same side the ridge entered.
    8. 14. FLOW OF RIDGES ULNAR LOOP ULNAR LOOP RADIAL LOOP THE ABOVE PATTERNS SHOW THE DIRECTION RIDGES FLOW IF LOCATED IN THE RIGHT HAND.

    11. 17. SUFFICIENT RECURVE A SUFFICIENT RECURVE consists of the space between the shoulders of a loop free of any appendages which abut upon it at a right angle on the outside of the recurve. 1. 2. 3. 4. 5. 6. 8. 7. S S S S S S S S S S S S S S S S Shoulders
    12. 18. SUFFICIENT RECURVE THE SHOULDERS OF A LOOP are the points at which the recurving ridge definitely turns inward or curves. S S S S S S 9. 10. 11.
    13. 19. APPENDAGE Attachment or Connection An appendage striking the outside of the recurve at a right angle will spoil that recurve.
    14. 20. LOOP PATTERN AREA PATTERN AREA includes the CORE, DELTA, and RIDGES which are used in the classification of a loop. T T PATTERN AREA
    15. 21. TYPELINES T T T T
    16. 22. Definition: The two innermost ridges that are parallel and surround or tend to surround the pattern area. T T T T TYPELINES
    17. 23. DELTA THE DELTA IS THAT POINT ON A RIDGE AT OR NEAREST THE POINT OF DIVERGENCE OF TWO TYPELINES, AND LOCATED AT OR DIRECTLY IN FRONT OF THE POINT OF DIVERGENCE. Area to be considered in front of the point of divergence of two typelines.

    19. 25. CORE THE APPROXIMATE CENTER OF THE PATTERN PLACED UPON OR WITHIN THE INNERMOST SUFFICIENT RECURVE. LOCATED ON THE SHOULDERS OF THE INNERMOST LOOP FARTHEST FROM THE DELTA. CORE CORE CORE CORE

    48. 54. ULNAR LOOP Ulnar Loops flow toward the little finger. 03 01 02 03 03 03 03 02 03 02 The direction of flow applies to the finger on the hand, not as they appear on the fingerprint card.
    49. 55. RADIAL LOOP Radial Loops flow toward the thumb. 03 52 03 53 01 55 01 53 01 01 The direction of flow applies to the fingers on the hand, not as they appear on the fingerprint card.
    50. 56. NOTE: RADIUS RIGHT HAND ULNA When a loop enters and exits from the THUMB side of the hand, the pattern will always be a “Radial Loop.” When a loop enters and exits from the PINKY finger, the pattern will always be an “Ulnar Loop.” There are NO exceptions to this rule!
