Edward John (blood spatter analysis pioneer)

Edward John was a pioneering figure in blood spatter analysis, a forensic science used to interpret patterns of bloodstains at crime scenes. His work helped establish that the shape, size, and distribution of blood drops can reveal critical details about how an injury occurred, the position of the victim and perpetrator, and the sequence of events. By developing methods to analyze bloodstain patterns systematically, John contributed significantly to crime scene investigation and testified in court to support investigations, making blood spatter analysis a valuable tool in modern forensic science.
