Forensic Science Facts: Fingerprint Processing

Question

Of the following pieces of evidence at a crime scene, which would be the most difficult to lift a latent fingerprint off of the surface? Any idea why?

1. The sticky side of recovered duct tape
2. A fired cartridge casing
3. A wet car door
4. A piece of notebook paper

Answer 1

I would say a piece of notebook paper. Reason to this is the property of adhesive properties of each material. Abc allows the fingerprint(s) to adhere to the material easier and hold the oil secretions firmly. Whereas, the notebook paper has poor adhesion and isn’t too realistic. This is based off adhesion properties, covalent bonding of water, and material. Hope this helps
