The role of a bloodstain pattern in an investigation can evolve significantly from crime scene to court. Through this process the BPA evidence can be considered by multiple actors with various remits, from the initial investigation and into the subsequent court process … and beyond. The investigator may initially use the distribution of bloodstains to identify possible mechanisms of production. When suspects are identified, the bloodstaining will be evaluated in light of the accounts that have been provided.
Throughout the criminal justice process, the analyst will be required to present an evidence-base that substantiates their observations and supports the conclusions that they present to the court. This can include to decision-makers whose only experience of BPA is from the television.
The BPA findings may also be assessed by other scientists, instructed on behalf of the defence or as part of a post-conviction review, and their role may include consideration of the original case record against a completely new set of propositions.
The original bloodstain pattern analyst must therefore ensure that their records can support every stage of the enquiry. The record must be consistent, comprehensive and complete, so that anyone who reviews their work can investigate the bloodstains as though they were looking through the original investigators eyes.
In this talk, I will discuss the role of bloodstain patterns across a number of criminal case investigations and, with the help of the audience, attempt to interpret some of the bloodstain patterns that have recently gained notoriety, thanks to Netflix
