Bloodstain patterns are some of the most crucial evidence that can be located at a crime scene. These patterns are created in such distinct manners that investigators may be able to recreate nearly every movement within a crime scene. Physics dictate the way that blood will travel throughthe air and the way that it will disperse once it makes contact with a surface. Through the years, crime scene investigators have been trained to understand the laws of physics and thephysical properties ofblood. Although these investigators have, for the most part, done an outstanding job, some cases have proved that not all investigators are able to accurately analyze bloodstain patterns. In these cases a physicist with specialization in forensic science may be employed to give their opinion of the actions within a crime scene.

A physicist trained in forensics or an investigator with physics training wouldmake a better bloodstain pattern analyst. Why?
