Timeline of bloodstain pattern analysis
Surprisingly to me the study of bloodstain patterns has been going on since the 1800’s. On the following page is a time line showing the history of bloodstain patterns interpretation/analysis. The timeline I made begins in the 1860’s and goes through the 1970’s, not every significant moment is included on this particular timeline.
1970’s – MacDonell worked under a LEAA grant, and completed 3 different articles through the 1990’s. He has trained many in law enforcement and has developed courses to continue to train analysts.

    In crime scenes, forensic scientist uses mathematics skills like geometry, trigonometry, distance and angle in bloodstain pattern analysis (BPA). BPA is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed. When determining BPA, analysts examine the size, shape, distribution, and location of the bloodstain to form opinions about what did or did not happen. Analysts uses those math skills to determine where the blood came from, how were the victim and perpetrator positioned when the crime happened, and what direction was the victim wounded.…

    This was however not the case for wallpaper where the blood could be seen moving up and down the bloodstain before finally forming the bloodstain. This may have been due to the amount of friction the blood encountered when moving along the surface – there would not have been much friction force in the case of the cardboard, however on the wallpaper, because it is a textured surface, there would have been a greater friction force. Given this finding, it would have been expected that the time taken for a bloodstain to form on the wood surface would have taken approximately the same time as the time taken for a bloodstain to form on wallpaper. This was however not the case, with the bloodstain forming in only 39.6 ms on wood. It was seen in the high-speed video of a bloodstain forming on wood that the blood travelled continuously in a downward direction meaning no extra time was spent with blood moving up and down the bloodstain. The bloodstains that took the shortest amount of time to form had the longest wave…
