Which are two common examples of forensic evidence?

• A. DNA analysis and fingerprint analysis
• B. Eyewitness testimony and alibi notes
• C. Motive assessment and intent
• D. Surveillance video and audio recordings

Answer: (D)

Forensic evidence consists of material traces that investigators can analyze to reconstruct events and establish facts. Surveillance video and audio recordings fit this idea because they capture real-world events in a format that can be objectively examined, preserved, and authenticated. They provide verifiable timelines, identify people or actions, and can be processed with forensic techniques to improve clarity, extract metadata, and verify authenticity, making them reliable sources in investigations. In contrast, eyewitness testimony and alibi notes rely on memory or statement-based information, which can be biased or incomplete, while motive and intent concern internal states that aren’t observable traces.
