Crime Scene Analysis: Hijacking and Kidnapping Investigation
This paper presents a forensic crime scene analysis of a hijacking and kidnapping scenario involving multiple suspects, two victims, and three distinct crime scenes. The analysis identifies each scene — the lorry trap and stop, the field abduction, and the derelict building hideout — and systematically examines the trace evidence opportunities at each location. The paper addresses evidence collection priorities for the Senior Investigating Officer (SIO), including fingerprints, hair fibers, tire tracks, footprints, blood, and cigarette DNA. It also outlines field scene processing procedures, from initial terrain survey and photography through detailed close inspection and evidence tagging for laboratory analysis.

What makes this paper effective
- Systematically organizes a multi-scene investigation by moving logically from the initial crime location outward to subsequent scenes, mirroring the actual sequence of events.
- Applies specific forensic vocabulary — trace evidence, fiber transfer, tire mark analysis, chain of custody tagging — in a practical, scenario-grounded manner.
- Balances breadth (covering all three scenes) with depth, providing concrete examples of evidence types at each location rather than speaking in generalities.
Key academic technique demonstrated
The paper demonstrates applied forensic reasoning: given a factual scenario, the writer identifies evidentiary significance in specific physical actions (e.g., a raider stepping back onto the verge, a smashed window, a cigarette left in a cab). This technique of linking physical events to evidence categories is central to forensic science writing and distinguishes analytical work from mere description.
Structure breakdown
The paper is organized into six numbered responses, each addressing a distinct forensic question. Sections 1–2 identify and characterize the crime scenes; Sections 3–4 catalog trace evidence opportunities at the lorry and field scenes respectively; Section 5 advises the SIO on evidence priorities once suspects are located; and Section 6 outlines step-by-step field scene processing methodology. The numbered format reflects an exam or structured assignment response style.
Identifying the Crime Scenes
There are three primary crime scenes in this case.
The first can be called the trap and stop scene. It begins at the point at which the raiders, driving a car with a faulty light, lured the lorry into slowing down by posing as a party in need of help. When the lorry slowed, the drivers of the 4x4 cut it off and deliberately caused the accident and forced a full stop. At this point, the lorry itself becomes a primary crime scene — both in terms of the assault on the occupants and, subsequently, during the hijacking and larceny.
The second scene takes place in the field, where Philip and Alison were separated and kidnapped. There are actually three sub-areas of evidence and thus three individual crime scenes under the same general rubric: the 4x4, the vehicle with the broken taillight, and the surrounding exterior areas. Philip was placed in the 4x4 and Alison in the other vehicle. Prior to being forced inside, however, Alison put up a struggle on the ground — making that ground the primary area of investigation until the two vehicles are located.
Finally, the derelict building provides the third general crime scene and is the location where the actual theft of the contents of the crates took place. The derelict building appears to have served as a hideout, and it is where Alison and Philip were taken following the kidnapping.
Trace Evidence at the Lorry Scene
The first crime scene involves a large number of opportunities for the detection of trace evidence. The driver's side window had been smashed with a metal bar, which could have been the same weapon later used to assault Philip. Two men opened the doors to the cab — both the passenger's side and the driver's side — and both doors may therefore contain trace evidence, including fingerprints and possible hair or clothing fibers. It should be noted that any blood found on the passenger cab door is likely to be Alison's, but it should be collected and analyzed regardless.
Evidence Opportunities During Unloading
During the unloading of the lorry, the potential for trace evidence transfer is high at several points. At least one of the raiders must have assisted in raising the roller shutter tailgate and lifting the tail before the crates were discovered inside. These actions required direct points of contact, and even if the raider had been wearing gloves, trace evidence such as clothing fibers would remain at those contact points. Because of the size of the crates, the raiders needed to open them while they were still housed inside the lorry, offering ample opportunity for depositing trace evidence — including fingerprints, hair, clothing fibers, and footprints.
Alison's mobile phone had most likely been taken by one of the raiders and could potentially be traced. Given that there was a strong smell of cigarettes in the cab after the raid, it is highly likely that investigators might recover a cigarette butt containing additional trace evidence and possibly DNA.
