Which of the following is a sign used for tracking persons from crime scenes?

• A. Foot/tire impressions
• B. Vehicle fluids
• C. Blood
• D. Scents

Answer: (A)

Tracking signs at a crime scene come from physical indicators left by a person as they move. Foot and tire impressions provide the most direct trail of movement, showing the direction traveled and enough detail to estimate size, gait, and speed. Casts or photographs of those impressions can be preserved and later compared to a suspect’s footwear or a vehicle’s tires, helping to reconstruct the path taken. Blood, while crucial for identifying who was present through DNA and linking a person to the scene, doesn’t give a reliable path of travel. Vehicle fluids can signal that a vehicle was involved but don’t map out the person’s exact route. Scents can be used in tracking with trained dogs, but the sign itself isn’t the human-tracking track evidence investigators use directly without canine assistance.
