Observation and Recall Flashcards

An officer witnesses a vehicle collision at an intersection. The striking vehicle was a blue sedan with partial plate 'KLM'. The driver, a heavyset male in his 40s wearing a red jacket, fled on foot heading northwest. Which detail is MOST critical to broadcast first?

Answer: The partial plate number

A partial plate number is the most actionable identifying detail for locating a specific vehicle quickly.

During a foot patrol, you observe a suspicious male loitering near a jewelry store. You note he is approximately 5'10", wearing a gray hoodie, blue jeans, and white sneakers, and has a tattoo on his left forearm. Twenty minutes later, a robbery is reported. What information should you radio in FIRST?

Answer: The full physical description and last known direction

A complete physical description combined with last known direction gives responding officers the best chance of locating the suspect.

You are asked to recall a scene you observed 30 minutes ago. Which memory strategy is MOST effective for accurately recalling specific details of a crime scene?

Answer: Write down everything immediately after leaving the scene

Writing notes immediately after observation preserves accurate detail before memory fades or becomes contaminated by later input.

A witness describes a getaway car as 'dark colored, maybe black or dark blue, four-door, with a loud exhaust.' An officer should record this description as:

Answer: A dark-colored four-door vehicle, possibly black or dark blue, with a loud exhaust

Officers must record witness descriptions exactly as given, including uncertainty, rather than making assumptions.

While on patrol, you drive past a house and notice the front door is ajar, a lamp is knocked over inside, and an elderly woman is standing on the porch looking distressed. Which observation is the STRONGEST indicator of a possible crime?

Answer: The combination of the open door, overturned lamp, and distressed resident

Multiple simultaneous indicators together — not any single one — constitute the strongest signal of a potential crime.

An officer studying a crime scene photograph later testifies about what she observed. Defense counsel challenges her recollection because the photo shows a detail she did not mention. What is the BEST explanation for this gap?

Answer: Selective attention causes observers to encode only salient or relevant details, missing background elements

Selective attention is a well-documented phenomenon where observers naturally focus on salient elements and miss peripheral details.

You observe two males arguing outside a bar. Male #1 is tall, blond, wearing a green shirt; Male #2 is shorter, dark hair, wearing a black jacket. Male #2 suddenly shoves Male #1 and runs east. To describe Male #2 accurately, you should note:

Answer: Height relative to Male #1, hair color, jacket color, and direction of flight

A complete description includes physical characteristics, clothing, and direction of travel so other officers can identify and locate the subject.
