Bloodstain Pattern Analysis: Forensic Types & Classification
When multiple free-falling drops of blood are produced from a stationary source onto a horizontal surface, it is known as a drip pattern. It results from blood drops falling into previously deposited wet blood stains or small pools of blood.
When examining drip trails and flows, the bloodstains appear to lead from one area to another. A bloodstain pattern resulting from an object striking liquid blood. A stain where the minor axis is narrower than the major axis. A bloodstain where the major axis and minor axis are equal lengths.
Bloodstain pattern analysis (BPA) is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed. Analysts examine the size, shape, distribution and location of the bloodstains to form opinions about what did or did not happen.
Characterizing drip patterns in bloodstain pattern analysis: An ...
2019年8月1日 · A drip pattern is a type of bloodstain pattern that is created when blood droplets impact another liquid, such as blood, to form a pattern that contains a parent stain with surrounding satellite spatter (Fig. 1) [1]. Important features of a drip pattern include the size and shape of the parent stain, and the distribution of its surrounding ...

2019年8月1日 · This work characterizes fundamental features of static drip patterns simulated for forensic bloodstain pattern analysis. The purpose of this study was to determine if and how two independent variables, impact velocity and droplet number, influence the parent stain size, shape and satellite spatter distribution of drip patterns created with ...
