Often latent fingerprints can be developed from the surface of adhesive tapes. Additionally tape composition, construction, and color can be compared with known sources. Comparisons can be made with the torn end of tape and a suspect roll of tape. The Laboratory will examine duct, vinyl electrical, and packaging tapes but will not examine cellulose acetate tape (e.g., Scotch tape). See Tape Database Document.
IMPOUNDING OFFICER PROCEDURES
Whenever possible, submit tape still adhered to the substrate. This minimizes the loss of trace evidence, latent fingerprints, or contact impressions. If it is not possible to submit the substrate, the tape may be manually removed and placed adhesive side down on a clean, colorless piece of plastic sheeting (e.g., overhead transparency film or Kapak tubular rollstock), not on cardboard, paper, or vinyl document protectors. Do not distort or tear the tape during removal.
If the tape is cut during removal, document and initial each cut. Use a method that produces a unique cutting pattern (e.g., pinking shears).
EVIDENCE OFFICER PROCEDURES
