Manslaughter has two forms, involuntary and voluntary. Involuntary manslaughter refers to a killing that is unintentional that results from recklessness or criminal negligence. An example of involuntary manslaughter is when a person in driving down the road over the speed limit and wrecks the vehicle, killing a passenger. There was no intent to kill the passenger, but the reckless driving was the cause. Voluntary manslaughter refers to killing another person without any intent during the heat of passion. The heat of passion refers to any circumstance that would cause an otherwise reasonable person to experience emotional or mental shock. For example, a husband and wife are arguing when the wife finds out her husband has been having an affair. During the argument, the wife pushes her husband down the stairs, where he hits his head and dies. This would be voluntary manslaughter because during the heat of passion, the wife pushed her husband down the stairs which led to his death.

Shoe prints, footprints and tire prints can be found to answer the same question. Impressions of these types of prints can be made to find out how many suspects were on the scene. The order in which the events took place can even be determined by the prints found on scene. Other common types of physical evidence found at crime scenes are glass, fibers, cloth fragments, string, cord, rope, tape, fingerprints and paint.

Examining a piece of glass can tell investigators what type of glass it was, as well as the direction the glass was broken or shot through. Cloth fragments, string, cord and rope may be evidence at the scenes of violent crimes such as homicide and murder. Hair and blood are other examples of physical evidence that can be transferred from suspects to victims. While there are many more forms of physical evidence
