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 …

Alteration of bloodstain patterns by Diptera: objective analysis based on Wonder’s 2001 criteria.
… the blood feeding activity, and blood artefact patterns created by flies following a blood meal. The respective trials were undertaken in a staged environment that can be considered operationally relevant to the field of bloodstain pattern analysis (BPA); in which approximately 500 flies per …

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 …

Impact, spreading, and drying of complex fluid drops
… spatial segregation and alter deposition patterns beyond single-component expectations. Together, these results establish a unified physical picture in which droplet footprints are understood as the cumulative outcome of impact, transport, and evaporation across multiple timescales. This …
