Which of the following is an example of evidence that could be related to a crime scene?

• A. Bodily fluids
• B. A stapler from another room
• C. A random book
• D. A calendar

Answer: (D)

Evidence at a crime scene includes physical traces that can tie someone to what happened. Bodily fluids are one of the most direct forms of such evidence because they can carry DNA, blood, or other biological markers. This makes them capable of linking a person to the scene or to a victim, or showing that contact occurred at a specific time or location.

A calendar could help establish timing if it contains relevant entries, but on its own it doesn’t prove involvement in the crime. A random book might become evidence only if it contains linking information—like notes, handwriting, or traces such as fingerprints—that connect it to the incident. A stapler from another room is similarly dependent on a clear link, such as traces or context showing how it relates to the event. Without those connections, it’s less directly indicative of the crime than bodily fluids.
