6.3 Physical Description Accuracy, Facial Features & Vehicle Identification
Key Takeaways
- The standardized Head-to-Toe physical description protocol encodes suspect descriptors systematically from gross demographic categories down to footwear and carried weapons.
- Facial composite comparison prioritizes permanent morphological landmarks (jawline geometry, nasal bridge profile, attached vs free ear lobes) over transient features (hair dye, facial hair, eyeglasses).
- The CYMBAL mnemonic (Color, Year, Make, Body style, And License) provides the universal protocol for rapid vehicle identification and BOLO radio broadcasts.
- Automotive body style analysis distinguishes 3-box sedans (separate trunk compartment) from 2-box hatchbacks and crossovers (shared passenger/cargo volume with rear liftgate).
- High-value vehicle identifiers include aftermarket wheels, window tint gradations, roof accessories, unique body damage, and Alberta licence plate categories.
6.3 Physical Description Accuracy, Facial Features & Vehicle Identification
Executive Summary: Rapid, accurate encoding and transmission of suspect physical descriptions and vehicle identifiers is a life-safety skill in police operations. On the Alberta Police Cognitive Ability Test (APCAT), candidates are tested on their ability to systematically record suspect descriptors using the standardized Head-to-Toe methodology, differentiate permanent facial morphological features from transient cosmetic alterations, and classify motor vehicles using the CYMBAL protocol. This section covers the standardized taxonomies used across Canadian law enforcement.
Systematic Suspect Encoding: The Head-to-Toe Methodology
When a frontline officer broadcasts a Be On the Lookout (BOLO) or logs an entry into the CPIC Person Category, descriptions must follow a strict, standardized sequence. This ensures dispatchers and perimeter containment units receive information in an intuitive, prioritized order.

The Operational Rationale for Top-to-Bottom Sequencing
- Demographics & Build First: Establishes the broad physical profile so officers can immediately rule out non-matching individuals from a distance.
- Face & Permanent Marks Second: Provides immutable identifiers that cannot be discarded during flight.
- Clothing & Footwear Third: Garments can be shed or altered (e.g., discarding an outer hoodie), but footwear is rarely changed during immediate foot flight.
- Weapons & Property Last: Alerts responding units to immediate tactical threats and stolen evidence.
Facial Composite Feature Comparison & Morphological Analysis
In photographic line-ups and suspect composite audits, investigators must analyze facial geometry. Criminals frequently alter their appearance following an offence (e.g., shaving beards, dying hair, donning glasses). Candidates must learn to distinguish between permanent anatomical landmarks and transient cosmetic features.

Permanent Anatomical vs. Transient Alterable Features
| Feature Category | Specific Attributes | Reliability Index | Forensic Utility |
|---|---|---|---|
| Permanent (Morphological) | Jawline bone structure, nasal bridge cartilage, attached vs. free ear lobes, inter-pupillary distance, facial scars, permanent tattoos. | High (Immutable) | Cannot be altered without extensive plastic surgery; primary basis for photo-pack identification. |
| Transient (Cosmetic) | Hair color/dye, hair length, facial hair (beard/mustache), eyeglasses, cosmetic makeup, baseball hats. | Low (Easily Altered) | Can be shaved, dyed, removed, or donned in minutes to disguise identity. |
Key Identification Rule: An attached ear lobe (where the ear lobe fuses directly to the side of the head without a hanging notch) is a genetically determined physical trait. A suspect with attached lobes cannot be the person shown in a clear photo with prominent free/detached hanging lobes.
Vehicle Identification & The CYMBAL Protocol
The CYMBAL mnemonic is the universal law enforcement standard for transmitting vehicle descriptions over police radio and Computer-Aided Dispatch networks.
┌─────────────────────────────────────────────────────────────────────────┐
│ THE CYMBAL VEHICLE PROTOCOL │
├──────────────┬──────────────────────────────────────────────────────────┤
│ C - Color │ Primary base color; secondary two-tone or matte wrap │
├──────────────┼──────────────────────────────────────────────────────────┤
│ Y - Year │ Approximate model year range (e.g., 2018 - 2022) │
├──────────────┼──────────────────────────────────────────────────────────┤
│ M - Make │ Manufacturer brand (e.g., Ford, Honda, Toyota, Dodge) │
├──────────────┼──────────────────────────────────────────────────────────┤
│ B - Body │ Specific structural configuration (Sedan, Hatchback, │

├──────────────┼──────────────────────────────────────────────────────────┤
│ A - And │ Conjunction linking body style to license details │
├──────────────┼──────────────────────────────────────────────────────────┤
│ L - License │ Plate alphanumeric characters & jurisdiction (Alberta) │
└──────────────┴──────────────────────────────────────────────────────────┘
Alberta Licence Plate Standards
- Standard Passenger Format: 7 characters (3 letters, 4 numbers, e.g.,
ABC-1234) on a white background with red lettering ("Wild Rose Country"). - Support Our Troops Format: 5 characters (1 letter, 4 numbers, e.g.,
T-1234orA-1234) with yellow ribbon insignia. - Commercial / Trailer Formats: Specific prefixes and numbering layouts.
- Mounting Rule: In Alberta, passenger vehicles are legally required to display a licence plate on the rear bumper only (no front plate required).
Distinguishing Automotive Structural Body Configurations
APCAT observation tests require candidates to distinguish between subtle automotive body configurations. Understanding structural pillars (A, B, C, and D pillars) and structural "boxes" is essential.

Automotive Body Classification Matrix
| Body Configuration | Box Architecture | Pillar Structure | Defining Structural Features |
|---|---|---|---|
| Sedan | 3-Box (Engine / Cabin / Trunk) | A, B, and C Pillars | 4 doors; fixed rear window; separate enclosed trunk with lid located below the rear glass. |
| Hatchback | 2-Box (Engine / Shared Cabin) | A, B, and C Pillars | 3 or 5 doors; rear liftgate incorporates rear window glass and opens full cargo volume. |
| Coupe | 3-Box or 2-Box | A and B/C Pillars | 2 passenger doors; sloping sporty roofline; shorter wheelbase. |
| Crossover (CUV) / SUV | 2-Box (Elevated Cabin) | A, B, C, and D Pillars | Elevated ride height; higher ground clearance; roof rails; top-hinged rear liftgate. |
| Pickup Truck | 2-Box / Cab-and-Bed | A, B, and C Pillars | Enclosed passenger cab (Regular, Extended, Crew) with a separate open rear cargo bed. |
| Minivan | 2-Box (Low Floor Unibody) | A, B, C, and D Pillars | Dual sliding side passenger doors; low step-in height; large 3-row cabin. |
High-Value Distinguishing Modifications & Damage
When standard make and model match numerous vehicles on the road, frontline officers rely on distinct aftermarket modifications and physical damage markers to establish positive identification:
- Aftermarket Wheels & Rims: Custom black alloy rims, chrome multi-spoke wheels, or missing hubcaps exposing black steel wheels.
- Window Tint Gradients: Factory rear privacy glass vs. dark limousine tint; illegal front driver/passenger side window tint (strictly restricted under the Alberta Traffic Safety Act).
- Roof Accessories: Roof racks, aerodynamic ski boxes, bicycle mounts, or LED light bars.
- Physical Body Damage: Dents in specific quarter panels, cracked windshields, mismatched replacement body panels, or distinct rust patterns along wheel wells.
- Decals & Badging: Bumper stickers, dealer badges, or removed manufacturer emblems.
A frontline patrol officer observes a vehicle fleeing an armed commercial robbery in Lethbridge. The officer must broadcast an immediate radio alert following the standardized CYMBAL protocol. Which of the following broadcasts correctly follows the complete CYMBAL sequence while providing accurate structural body classification?
A recruit officer is preparing an operational Be On the Lookout (BOLO) broadcast for a robbery suspect who fled on foot into a residential subdivision. Following the standardized Canadian police Head-to-Toe methodology, what is the proper sequence for structuring the suspect's physical profile?
A detective compares a surveillance image of a robbery suspect against historical booking photographs. In the surveillance image, the suspect displays dyed red hair, thick black-framed eyeglasses, a clean-shaven face, and distinctly attached ear lobes (fused to the head without a hanging notch). A candidate booking photograph shows an individual with brown hair, no glasses, a full beard, and prominent free (detached) hanging ear lobes. Which morphological feature conclusively demonstrates that the individual in the booking photo is NOT the robbery suspect?
During a hit-and-run investigation, an officer must distinguish between a compact hatchback, a sedan, and a subcompact crossover utility vehicle (CUV). Which structural design characteristic definitively classifies a motor vehicle as a 3-box sedan rather than a hatchback or crossover?
