LW60075E - Crime Scene Analysis: Forensic Investigation Case Study

This case study presents a detailed analysis of a crime scene at a university building, focusing on the forensic investigation process. The initial report outlines the scene's description, including the victim's position, potential entry points, and objects found, such as a passport, wallets, wine bottles, a handcuff, and a blood-stained shirt. As a forensic investigator, the actions taken involve collecting biological evidence (blood samples), latent print evidence (fingerprints), trace evidence (hair fibers), digital evidence (mobile phone data), and drug evidence (wine analysis). The collected samples are sent to the forensic laboratory for further investigation, and the report emphasizes the importance of securing the scene, documenting findings, and communicating with colleagues. The final report, including DNA analysis, will be crucial for the simulated courtroom scenario.

10. Hair found on the sofa.
 Potential murder weapon: The knife found lying beside the bed is supposed to be the
potential murder weapon.
Role as Forensic Investigator
 Samples collected: a wide range of physical evidence has been collected from the crime
scene, which can be deemed probative for further investigation and analysis.
1. Biological evidences: blood sample collected from the shirt and the cloth, sent for
DNA detection.
2. Latent print evidence: the coin, the bolt, the wine bottles, the glasses, the wallets
and the knife has been sent for finger print detection. Footprint samples are
collected from the carpet.
3. Trace evidence: hair fiber samples sent for DNA recognition.
4. Digital evidence: the mobile phone found from the scene is sent for data and call
log recovery.
5. Drug evidence: the wine bottles are sent for detecting the presence of any foreign
particle or irregular chemical composition.
 Several Photographs and paper documents are collected which are sent for thorough
review of the investigation team.

3CRIME SCENE ANALYSIS
 The areas of likely contact of the victim and the murdered is swabbed thoroughly for
collecting low-level DNA traces.
 Communication with fellow colleagues at the crime scene to understand and assess the
scene better and to consider the different perspectives that would help to draw a
conclusion.
Actions taken
The scene has been guarded, secured and thoroughly assessed as quickly as possible to
prevent the contamination and tampering of the evidences. The significant area of the crime
scene has been identified and marked. The physical evidences has been collected, preserved,
packaged and sent to the forensic laboratory for further investigation. Detailed report and log of
the found objects has been done for data tracking. The physical evidences has been sent to the
forensic laboratory. A primary survey has been conducted to find out the potentially significant
evidences. The entire crime has been documented and the situations has been recorded minutely.
The analysis of the objects found and the samples collected would be incorporated in the
final report of the Forensic Investigator, which would be complete after assessing the DNA
report.
