Question 1

What is the purpose of a 'baseline measurement' technique in crime scene sketching?

Accepted Answer

To establish a fixed reference line from which measurements to evidence are taken

Answer

The baseline technique uses a straight reference line (often a wall) from which perpendicular measurements locate evidence precisely on the sketch.

Question 2

Which type of crime scene sketch shows a bird's-eye view of the scene?

Accepted Answer

Floor plan (overhead) sketch

Answer

A floor plan or overhead sketch depicts the scene from directly above, showing the spatial relationship between evidence and fixed structures.

Question 3

When documenting bite mark evidence on a victim, the most critical supplemental measurement tool is:

Accepted Answer

An ABFO No. 2 scale

Answer

The ABFO No. 2 scale is the forensic standard for bite mark photography because it provides circular reference points and L-shaped rulers for accurate distortion correction.

Question 4

A supplemental report filed after the initial crime scene report typically documents:

Accepted Answer

New evidence, additional interviews, or updated findings discovered after initial filing

Answer

Supplemental reports capture new information, follow-up actions, and updated findings that arise after the initial report has been filed.

Question 5

The 'triangulation' method in crime scene sketching involves:

Accepted Answer

Measuring the distance from an evidence item to two fixed points

Answer

Triangulation locates evidence by measuring its distance from two fixed, known points, creating a triangle that precisely fixes the item's position.
