  4. Agenda09.08.08 • Review: Fingerprint Classifications • Notes: Taking Legible Fingerprints

  5. Taking Legible Fingerprints The How To’s of the FBI

  6. Why Take Fingerprints? • Identify Suspects • Establish Innocence • Identify Victims • Document People • Other Ideas?

  7. Who Can Be Fingerprinted? • Any individual arrested for a crime. • Civilians seeking employment with government agencies. • Immigrants or individuals entering the country on a visa may be fingerprinted. • Civilians required to undergo background checks.

  8. Fingerprint Equipment • Ink or Chemicals • Standard Fingerprint Card • Livescan (electronic)

  9. “10-Card” Examples

  10. Taking Fingerprints • The two types of impressions: • Rolled Impression • Plain Impressions

  11. Fingerprinting Steps • Fingers to be printed must be clean and dry. • The individual being fingerprinted should stand in front of and at a forearm's length from the fingerprinting device. The examiner should stand to the right and rear of the person taking the fingerprints.

  12. Fingerprinting Steps • Encourage the individual to relax. Ask them to look at a distant object to distract them. • Grasp the individual's right hand at the base of the thumb with your right hand. Cup your hand over the their fingers, tucking under those fingers not being printed. Guide the finger being printed with your left hand.

  13. Fingerprinting Steps • Roll the finger on the pad so that the entire fingerprint pattern area is evenly covered with ink. The ink should cover from one edge of the nail to the other and from the crease of the first joint to the tip of the finger.

  14. Fingerprinting Steps • To take rolled impressions the side of the bulb of the finger is placed upon the card and the finger is rolled to the other side until it faces the opposite direction.

  15. Fingerprinting Steps • The hand should be rotated from the more difficult position to the easiest position.This requires that the thumbs be rolled toward and the fingers away from the body. • Roll each finger from nail to nail taking care to lift each finger up, to avoid smudging.

  16. Fingerprinting Steps • Plain impressions are printed last, at the bottom of the card. Press the individual's four fingers (on the right hand), keeping the fingers together, on the surface of the fingerprint card at a forty-five degree angle. • Print both thumbs simultaneously in the plain impression thumb blocks.

  17. Fingerprinting Steps • Complete the information at the top of the fingerprint card.

  18. Special Circumstances • Can you think of any special circumstances that would interfere with the fingerprinting process?

  19. What Do You Do With: • Amputations: • The condition should be noted in the appropriate block of the fingerprint card. • Amputation (AMP) • XX • Missing at Birth (MAB)

  20. What Do You Do With: • Bandaged Fingers or Hands: • Place the notation, "Unable to Print" or "UP" in the appropriate finger block.

  21. What Do You Do With: • Scars: • Fingerprints should be taken as they exist. • Scars can be noted as "Scarred," but it is not required.

  22. What Do You Do With: • Deformities: • Special equipment (e.g. a fingerprint spoon) may be needed.

  23. What Do You Do With: • Worn Fingerprints: • Light pressure and very little ink are used. • “Milking the fingers" can be used. • Apply pressure or rub the fingers in a downward motion from palm to fingertip.

  24. What Do You Do With: • Extra Fingers: • The thumbs and the next four fingersshould be printed only.

  25. What Do You Do With: • Webbed Fingers or Split Thumbs: • Print if possible or make a notation.

  26. What Do You Do With: • Webbed Fingers or Split Thumbs: • Print if possible or make a notation.
