Analysis of blood stains at a crime scene can be critical in solving a crime. Often the blood type can be determined and matched to potential suspects. Students will utilize simulated blood and blood typing sera to learn the principles of blood typing procedures. They will extract and type blood from items found at a mock crime scene and determine possible connections to potential suspects. The materials can be easily adapted to your own crime scene scenario and can be used to produce crime scene stains of your own design. No blood or blood products are used.
