Assignment 2 Semester 1 2025
Unique Number: 524227

QUESTION 1.1
The Locard Exchange Principle states that whenever two objects come into contact, there is
always a mutual exchange of materials. In forensic science, this principle is foundational, as
it implies that a perpetrator of a crime will bring something into the crime scene and leave
with something from it. This exchange can include microscopic materials such as fibers, hair,
skin cells, or soil particles (Van der Westhuizen, 2021).
In the context of the case study, the Locard Principle can be applied to the suspects'
vehicles—the BMW X1 and the Audi A4. These vehicles are crucial contact points between
the suspects, their environment, and any weapons or tools used during the attempted
robbery. Investigators can examine the interior and exterior of the cars for trace evidence
such as gunshot residue, hair, skin flakes, or fibers from the suspects' clothing. Moreover,
evidence such as fingerprints or DNA on door handles, steering wheels, and seatbelts can
link specific suspects to specific roles or activities. Even soil or plant matter from a previous
crime scene might be recovered from the wheels or undercarriage, potentially connecting
the suspects to other CIT robberies.

QUESTION 1.2
Several types of physical and biological evidence may be transferred between the
suspects and the vehicles during the commission of a crime. According to the Locard
Exchange Principle, this interaction results in mutual contamination between the
environment, the suspect, and the vehicle (Van der Westhuizen, 2021).
First, biological evidence such as hair, blood, saliva, or sweat may be transferred
when suspects touch or bleed onto vehicle surfaces. DNA from such materials can
directly identify individuals. Second, trace evidence like fibers from clothing or
upholstery may be left behind, helping to confirm physical presence inside a specific
vehicle. Latent fingerprints may be deposited on smooth surfaces like door
handles, dashboards, and weapons, linking suspects to objects or roles. Gunshot
residue (GSR) on the seats, doors, or floor mats could confirm that firearms were
discharged within the vehicle. In addition, footwear impressions on the mats or dirt
