Question 1

In forensic science, 'class characteristics' of evidence are features that:

Accepted Answer

Narrow the source of evidence to a group but cannot identify a single unique source

Class characteristics, such as caliber of a bullet or general tread pattern of a tire, limit the possible sources but cannot definitively match evidence to one specific item.

Question 2

The method of documenting a crime scene using a sketch with measurements and compass orientation is called:

Accepted Answer

Rough sketch followed by a finished scale diagram

Answer

A rough sketch drawn at the scene includes measurements and compass bearings, which are later used to produce an accurate, to-scale finished diagram for court.

Question 3

Superglue (cyanoacrylate) fuming is used to develop latent fingerprints on:

Accepted Answer

Nonporous surfaces such as plastic, glass, and metal

Answer

Cyanoacrylate vapors polymerize on the amino acids in latent print residue, producing a white, durable deposit on nonporous surfaces.

Question 4

Which type of search pattern is best suited for a large outdoor crime scene with multiple investigators walking in parallel lines?

Accepted Answer

Strip/lane search

Answer

The strip (lane) search assigns investigators to parallel rows so the entire area is systematically covered without leaving unsearched gaps.

Trace evidence consists of minute quantities of material transferred through Locard's principle, including hairs, fibers, soil, glass, and paint chips.
