Mock Forensic Crime Scene Evidence Presentation

~3 min read

Abstract

This paper presents a mock forensic crime scene evidence report documenting the collection and preliminary analysis of physical evidence recovered from a homicide scene at a construction supply warehouse. The report covers standard crime scene procedures, including the supervised repositioning of a waste container to preserve the victim's position, and catalogs both organic evidence — such as blood samples, human tissue, skin, and hair — and inorganic evidence, including shoe imprints, latent fingerprints, and personal effects. The report demonstrates the systematic documentation and chain-of-custody protocols used in forensic investigations.

What makes this paper effective

Uses precise, professional forensic language consistent with real crime scene documentation, lending authenticity to the mock report format.
Systematically organizes evidence into organic and inorganic categories, mirroring standard forensic practice and making the report easy to follow.
Includes specific quantitative details (e.g., droplet sizes of 1.0–2.0 mm, exact dollar amounts, strand counts) that demonstrate attention to evidentiary specificity.

Key academic technique demonstrated

The paper demonstrates the use of technical report writing in a forensic science context. Rather than constructing a discursive argument, the author structures information as an official evidentiary record, using passive voice and precise measurements to simulate the objective, depersonalized tone required in actual forensic documentation. This is a valuable model for students learning professional and scientific writing formats.

Structure breakdown

The report opens with a narrative background section establishing the crime scene context and supervisor decisions made on-site. It then proceeds to two evidentiary sections — organic and inorganic — each cataloging specific items recovered. A brief references section closes the paper. The structure directly mirrors the format of a real forensic evidence report, making it useful as a template for understanding how such documents are organized and composed.

Background and Scene Overview

The victim was found facedown behind an industrial waste container on the premises of a construction supply warehouse. After standard measurements and crime scene photography were completed, the waste container was moved under the direction of the crime scene supervisor to facilitate direct access without disturbing the condition of the corpse to the extent that would otherwise have been necessary. The crime scene supervisor determined that preserving the precise position of the victim outweighed the comparative value of preserving the position of the waste container. The procedure was video recorded and the scene re-secured by detectives immediately afterwards.

Organic Evidence Collected

A substantial amount of blood was collected from a pool underneath the victim's head, together with smaller amounts of blood from sixteen other points within the immediate vicinity of the victim. Each individual sample was preserved under standard collection protocol and stored separately. A tissue containing blood was also recovered from the area and preserved separately. All blood samples were subsequently determined to be of human origin. Of the seventeen samples, twelve were positively identified as belonging to the victim, and the remaining five were identified as having come from a different individual. Those five samples were recovered from the victim's mouth and chin and from a series of small (1.0–2.0 mm) droplets found successively further away from the victim.

A piece of human flesh subsequently identified as a portion of the outer left ear — originating from the same unknown source as the five blood specimens not associated with the victim — was recovered from the inner portion of the victim's button-down cotton shirt.

After completion of standard measurements and photographs of the victim, the hands were separately bagged to preserve any evidence contained thereon. Subsequent forensic examination and analysis disclosed organic evidence in the form of human skin and blood identified as originating from the same source as the other blood and tissue samples not associated with the victim. Thirty-six strands of hair subsequently positively identified with the victim were recovered from the external clothing, as well as nine strands of human hair not identified with the victim.
