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.

A comparison must be made between the genetic markers in the victim s blood and the suspect's blood.
Potential crime scene evidence such as saliva, bite marks, semen, hair, skin tissue under the finger nails, and other trace materials may be found on the victim(s). Transferred evidence such as cosmetics, vaginal fluid, hair from the victim, and blood may also be found on the suspect.
