Though the use of blood type in a forensic investigation is not enough to prove guilt, it may aid in exonerating
a potential suspect. In this activity, students act as lab technicians and assist
investigators by examining evidence collected at a crime scene. Students first use a
presumptive blood test to determine if a substance on a stained piece of cloth may
be blood, and then determine the blood type of a sample collected at the scene.
Students then compare their results to those of samples provided from two suspects.
