Which item is not part of the evidence triangle?

• A. Motive
• B. Location
• C. Witness
• D. Clue

Answer: (C)

The evidence triangle centers on three elements that connect a crime to its context: motive, location, and clues. Motive explains why someone would commit the crime, location fixes where the crime occurred or where evidence originates, and clues are the physical traces found at the scene that guide investigation. Witness, while crucial as a source of information, falls under testimonial evidence rather than being a structural part of the triangle. It provides accounts from people rather than the direct links the triangle emphasizes. So the item not part of the evidence triangle is the witness.
