Obtaining Fingerprint Impressions > Procedures for Unusual Circumstances

Fingerprinting Deformities (Extra or Webbed Fingers)

If a subject has more than 10 fingers, as occasionally happens, the thumbs and the next 4 fingers should be printed, and any remaining fingers should be printed in the additional information field on the face side of the fingerprint card with a notation made to the effect that these impressions are extra fingers.  When a person with more than 10 fingers has an intentional amputation performed, it is invariably the extra finger on the little finger side which is amputated.

It also happens, not infrequently, that a subject will have two or more fingers webbed or grown together making it impossible to roll such fingers on the inside.  Such fingers should be rolled, however, as completely as possible, and a notation made to the effect that they are joined.

Split thumbs, i.e., thumbs having two nail joints are classified as if the joint toward the outside of the hand were not present.  In other words the inner joint is used, and no consideration whatever is given to the outer joint.

The above situations can also present a problem when taking prints on a livescan device.  Basically, the same rules should apply.  For any extra fingers, do not roll fingers and/or thumbs located on the outside of the hand.  Only capture the inside thumb and the next 4 fingers of each hand.  For all webbed fingers, capture only one side at a time to insure an image is in each box even though you will probably be unable to make a complete roll.  A notation should be made in the “Additional Information/Basis for Caution” box of the fingerprint card.

NOTE:  Agencies are urged to contact the Crime Information Bureau for assistance when unusual circumstances not covered in the Section are encountered.
