However, in resting horses, a heart rate over 80 can be a sign of a serious problem. If a calm horse has a pulse that is consistently over 60, it can also be a problem. Things that can increase the horse's heart rate include exercise, fear, pain, stress, and excitement.
Because blood analysis is a comparison analysis (comparison of the victim's blood and the suspect's blood to blood found at the crime scene), reference blood samples are needed from the victim and suspect. A comparison must be made between the genetic markers in the victim s blood and the suspect's blood.
In the episodes where the blood is spattered or in a large pool, the pattern of the blood varies from scene to scene. For example: A man is killed and the blood is sprayed across a desk. The pattern in scene 1 (finding the body) will be different than in scene 2 (going back to the crime scene for further evidence).
