There is no specific classification for some of the vilest acts in society that are above murder in the first degree.
The person committing these crimes is known as a spree killer. They pick off their victims at random most of the time, but they do so in large numbers all at once or over a very short time period.
This book contains 10 names and stories of people that have committed such a horrendous crime. You might remember the tragedy that they perpetrated but not be familiar with their personal story.
