1. crime scene investigators believe the suspect left a fingerprint on a ransom note written on notebook paper. which method should be use to visualize and collect the prints?

a. photography
b. powder
c. super glue fuming
d. ninhydrin

Explanation:

1. Visible prints are visible to the naked eye. Patent prints are a type of visible print. Plastic prints are three - dimensional impressions. Latent prints are not visible and require development techniques.
2. Footprints are not commonly used because they are not commonly found on crime scenes and there is no extensive database of known footprints compared to fingerprints.
3. Visible prints can be photographed directly. Tape is used for latent prints on non - porous surfaces, powder for latent prints on porous surfaces, and super glue fuming for latent prints on non - porous surfaces.
4. The image (assuming it has a central core with ridges flowing in a circular pattern) is a whorl. An arch has ridges that rise in the center and flow out, and a loop has ridges that enter from one side, loop, and exit from the same side.
5. Cyanoacrylate fumes (used in super glue fuming) are created from superglue.
6. The first image (assuming it is a developed latent print with powder) is a latent print (B).
7. The second image (assuming it is a three - dimensional impression) is a plastic print (C).
8. The third image (assuming it is a visible print) is a patent print (A).
9. Ninhydrin reacts with amino acids in fingerprints on porous surfaces like notebook paper. Photography is for visible prints, powder for some latent prints (but not typically on paper as well as ninhydrin), and super glue fuming for non - porous surfaces.
