1. An investigator conducting a crime scene search at the scene of a violent crime has certain responsibilities and procedures to follow related to evidence collection. Of the following steps, which one is not required of the on-scene investigator?

A. Recognize or discover relevant physical evidence.

B. Handle and package evidence to avoid breakage, loss, contamination, or questionable chain of custody problems.

C. Record where, how, and by whom the evidence was collected.

D. Test blood samples collected for the presence of DNA.

is it D

2. When an investigator moves from examining related pieces of evidence at a crime scene to drawing an inference or developing an explanation of the crime from separate pieces of evidence or observations, the investigator is said to be using:

inductive reasoning.

deductive reasoning.

procedural reasoning.

preconceived notions.

is it A

I agree with both of your answers.

To answer the first question, the investigator does not need to perform option D, which is testing blood samples for the presence of DNA. This step typically falls under the jurisdiction of a forensic laboratory and would not be performed on-scene by the investigator.

To answer the second question, when an investigator moves from examining related pieces of evidence at a crime scene to drawing an inference or developing an explanation of the crime from separate pieces of evidence or observations, they are using inductive reasoning. Inductive reasoning involves using specific observations or evidence to make general conclusions or predictions. Deductive reasoning, on the other hand, starts with general premises and uses logic to arrive at specific conclusions. In this case, the investigator is using inductive reasoning to create an explanation based on separate pieces of evidence.
