D Correct answer
Explanation

DNA analysis is a forensic technique used to identify individuals based on their genetic material. It is not typically used in forensic psychology, which focuses on the psychological aspects of criminal behavior.

Multiple choice

Which of the following is NOT a common type of evidence used in criminal profiling?

  1. Physical evidence

  2. Behavioral evidence

  3. Testimonial evidence

  4. DNA evidence
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Testimonial evidence, such as witness statements, is not typically used in criminal profiling. Criminal profiling relies primarily on physical evidence and behavioral evidence to infer the criminal's characteristics and behavior.
