What does the triangle of evidence refer to in crime scene analysis?

• A. Demonstrates the chain of custody
• B. Connects both the suspect and the victim to a scene
• C. Establishes the admissibility of testimony
• D. Determines the time of death

Answer: (B)

The triangle of evidence is a visual tool that shows how evidence connects three elements: the scene, the victim, and the suspect. It helps investigators see how pieces of evidence link the suspect to the location of the crime and to the victim, establishing presence, access, or opportunity. This framing supports evaluating alibis and motives by illustrating the relationships among who was at the scene and who the victim was with or connected to. It isn’t about the chain of custody (which tracks evidence handling), nor does it determine admissibility of testimony (a legal standard), and it doesn’t directly establish time of death (a forensic determination).
