INTRODUCTION Mass murder cases are defined by the FBI as an incident or more than three people were killed on the same day (Petersen & Farrington, 2007). Mass killers are complex and can be examined through a number of common factors, such as violent incidents, weapon choices, mental illnesses. The motivation and method of running the Holocaust can be easily categorized into specific groups Through these definitions and review of specific cases, the thoughts of mass murderers can be understood.
All murders are tragedies, but carnival, continuous homicide, mass murder are considered to be particularly visible. First of all, these homicides lack a clear motive; for most homicides, the reason is either to demand retaliation or to gain economic benefits. This is usually not the case when a person kills an unknown person, but people who can only understand violence or try to mark them and those who commit them. Imitation of the killing brought another knot to the entanglement - these homicides were already caused by the murder of others. Some people think that this type of murderer was born in 1912. Media coverage on Jack's murder case caused many similar criminal acts and the term "imitation effect" was born.
Mass murder cases have been well documented throughout the 20th century. In the most comprehensive study of events in the 20 th century America, Grant Dewey investigated a group of 909 murder cases between 1900 and 1999. He has confirmed a unique and attractive pattern of group murder over the years (1). The 20th century is characterized by two large murder peaks or waves. One wave appeared in the 1920's and 1930's, the second wave appeared in the mid-1960's and lasted until the mid-1990's. The period separating the two peaks - the decades of the 1940s and 1950s - represents a relatively quiet phase of mass murder (2).
According to statistics, there is a direct relationship between men who commit domestic violence and collective killers. Both Stephen Paddock and Devin Kelley abuse their spouses. Charles Whitman, one of the most infamous slaughter, killed 14 women and killed his wife and mother before ramping up to the tower. The link has been confirmed many times. NPR recently reported that 54% of large shooting games are committing close partner violence. New Yorkers also reported this link. What are general clues? In the last two cases, domestic violence allegations did not prevent them from acquiring weapons. What are you doing to solve this problem? No Well, more guns because it solved everything
