Procedures for collecting/lifting fingerprints

1. Photograph any visible fingerprints that you observe.

2. Carefully dip the brush into the appropriate powder. Apply a small amount of powder to the tip of the brush.

3. Apply the powder to the surface with a light twirling motion over the area to be processed. If a heavy deposit appears on a fingerprint, gently brush off the excess powder with a light twirling motion.

4. Photograph any latent fingerprints that have been developed.

5. Apply a short piece of lifting tape. This must be pressed well onto the surface.

6. Slowly remove the lifting tape from the surface and place it on a backing card that is of contrasting color to the powder being used.

7. Properly fill out the back of the backing card with the proper information.
