Fig. 1 Work flow schematic: DNA profiles from latent ridge impressions. A) Starting material: latent ridge impression enhanced with powder (fingerprint). B) Lifted fingerprint on hinge card (suitable for imaging). C) ‘Ghost’ fingerprint left on evidence post-lifting. D) Exposed fingerprint on lift card, note transparent liner being held by gloved hand. E) Collection of ‘left-behind’ material using swab and collection buffer. F) Represents total of fingerprint evidence=lift card+recovered left-behind material. G) Immobilized lift card in lysis chamber, note O-ring, binder clips. H) Swab used to recover left-behind material is used to collect extract from incubated lysis chamber. I) total lysate recovered after spin basket; note that a second proteolytic digestion is performed on this material. J) Combined lysate=lysate from lift card+lysate from reserved swab purified on Xs column; note retained powder in column (left) and clear purified lysate (right). K) GeneScan electropherogram of CE analyzed PowerPlex 16 PCR reaction.
