The factors affecting the recovery of bloodstain evidence from buried clothing.
… project investigates the potential loss of bloodstain evidence on clothing that occurs following violent crimes. Throughout the current project, it is identified that there is a prominent lack of literature that focuses on determining what soil parameters impact the survival of buried …

Alteration of bloodstain patterns by Diptera: objective analysis based on Wonder’s 2001 criteria.
… operationally relevant to the field of bloodstain pattern analysis (BPA); in which approximately 500 flies per experiment were exposed to tray of 500ml of horse blood in a sealed 3m x 3m gazebo for a period of approximately 72 hours. The resulting patterns, consisting of a total of …

Investigating the influence of substrate on the ambiguity of features of drip and transfer patterns in bloodstain pattern analysis
In bloodstain pattern analysis (BPA), two common bloodstain patterns that have been under-researched are transfer (especially wipes and swipes) and drip patterns. The works presented in this thesis investigate the features present in these pattern types and their variability on different substrate …

The analysis of the artefacts produced by forensically significant blowfly (Diptera: Calliphoridae) activity and their effect on bloodstain pattern analysis
Violent crimes involving bloodshed may result in bloodstains spattering on the surrounding surfaces. Accurate analysis of bloodstains at the scene can provide investigators with insights into the series of events that occurred during the execution of a violent crime. At a crime scene, blowflies …

Characteristics of bloodstains on waterproof fabrics
… involved. Blood evidence can be the subject of bloodstain pattern analysis (BPA) to ascertain the details of a blood shedding event as well as deoxyribonucleic acid (DNA) analysis to identify potential individuals that were present at the event. BPA becomes more complicated when bloodstains are …

Computational and laboratory investigations of a model of blood droplet flight for forensic applications
… is to develop an accurate framework for forensic Bloodstain Pattern Analysis (BPA).

Impact, spreading, and drying of complex fluid drops
A liquid drop impacting a surface leaves behind a footprint that encodes the history of its deformation, transport, and drying. Yet the final stain is not determined by impact alone. It emerges from a sequence of coupled processes—rapid inertial spreading, capillary-driven relaxation, contact-line …

Mathematical modelling of blood spatter with optimization and other numerical methods
The current methods used by forensic experts to analyse blood spatter neglects the influence of gravitation and drag on the trajectory of the droplet. This research attempts to suggest a more accurate method to determine the trajectory of a blood droplet using multi-target tracking. The …
