Victimology is the study of victimization, including the psychological effects on victims, the relationship between victims and offenders, the interactions between victims and the criminal justice system—that is, the police and courts, and corrections officials—and the connections between victims and other social groups and institutions, such as the media, businesses, and social movements.
A serial killer is typically a person who murders three or more people, usually in service of abnormal psychological gratification, with the murders taking place over more than a month and including a significant period of time between them. While most authorities set a threshold of three murders, others extend it to four or lessen it to two.
Mass murder is the act of murdering a number of people, typically simultaneously or over a relatively short period of time and in close geographic proximity. The FBI defines mass murder as murdering four or more people during an event with no "cooling-off period" between the murders. A mass murder typically occurs in a single location where one or more people kill several others.
Homicide occurs when a person kills another person. A homicide requires only a volitional act or omission that causes the death of another, and thus a homicide may result from accidental, reckless, or negligent acts even if there is no intent to cause harm. Homicides can be divided into many overlapping legal categories, including murder, manslaughter, justifiable homicide, assassination, killing in war, euthanasia, and capital punishment, depending on the circumstances of the death. These different types of homicides are often treated very differently in human societies; some are considered crimes, while others are permitted or even ordered by the legal system.
A spree killer is someone who commits a criminal act that involves two or more murders or homicides in a short time, in multiple locations. The U.S. Bureau of Justice Statistics defines a spree killing as "killings at two or more locations with almost no time break between murders".
A lust murder is a homicide in which the offender searches for sexual satisfaction by killing someone. Lust murder is associated with the paraphilic term erotophonophilia, which is sexual arousal or gratification contingent on the death of a human being. The term lust killing stems from the original work of Richard von Krafft-Ebing in his 1898 discussion of sadistic homicides. Commonly, this type of crime is manifested either by murder during sexual activity, by mutilating the sexual organs or areas of the victim's body, or by murder and mutilation. The mutilation of the victim may include evisceration, displacement of the sexual organs, or both. The mutilation usually takes place postmortem. Although the killing sequence may include an act of sexual intercourse, sexual intercourse does not always occur, and other types of sexual acts may be part of the homicide.

A murder–suicide is an act in which an individual kills one or more people before killing themselves. The combination of murder and suicide can take various forms:
Femicide or feminicide is a hate crime broadly defined as "the intentional killing of women or girls because they are female," though definitions vary depending on cultural context. Feminist author Diana E. H. Russell first defined the term in 1976 as "the killing of females by males because they are female." Others include the killing of females by females.
In the United States, the relationship between race and crime has been a topic of public controversy and scholarly debate for more than a century. Crime rates vary significantly between racial groups. Academic research indicates that the over-representation of some racial minorities in the criminal justice system can in part be explained by socioeconomic factors, such as poverty, exposure to poor neighborhoods, poor access to public education, poor access to early childhood education, and exposure to harmful chemicals and pollution. Racial housing segregation has also been linked to racial disparities in crime rates, as Blacks have historically and to the present been prevented from moving into prosperous low-crime areas through actions of the government and private actors. Various explanations within criminology have been proposed for racial disparities in crime rates, including conflict theory, strain theory, general strain theory, social disorganization theory, macrostructural opportunity theory, social control theory, and subcultural theory.
Jack Levin specializes in research on murder, prejudice and hate, sociology of aging and sociology of conflict at Northeastern University in Boston, Massachusetts. He has interviewed and corresponded with brutal killers, such as the Hillside Strangler and Charles Manson, and other violent criminals: serial killers and rapists, mass murderers, and vicious hatemongers. He is also asked by news and television reports to comment on important occurrences of homicide or hate. Along with interviews, writing material, teaching classes, and research Levin has also given talks about violence or hate to groups including the White House Conference on Hate Crimes, Department of Justice, the Department of Education, OSCE’s Officer for Democratic Institutions and Human Rights and the International Association of Chiefs of Police. Jack Levin has authored and co-authored over 30 books and has written and published over 200 articles.
Gun violence in the United States results in tens of thousands of deaths and injuries annually, and was the leading cause of death for children 19 and younger in 2020. In 2018, the most recent year for which data are available as of 2021, the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics reports 38,390 deaths by firearm, of which 24,432 were by suicide. The rate of firearm deaths per 100,000 people rose from 10.3 per 100,000 in 1999 to 12 per 100,000 in 2017, with 109 people dying per day or about 14,542 homicides in total, being 11.9 per 100,000 in 2018. In 2010, there were 19,392 firearm-related suicides, and 11,078 firearm-related homicides in the U.S. In 2010, 358 murders were reported involving a rifle while 6,009 were reported involving a handgun; another 1,939 were reported with an unspecified type of firearm. In 2011, a total of 478,400 fatal and nonfatal violent crimes were committed with a firearm. Gun crimes are covered by 18 USC 922 and 18 USC 924, which are the principal federal firearm statutes.
A familicide is a type of murder or murder-suicide in which one kills multiple close family members in quick succession, most often children, spouses, siblings, or parents. In half the cases, the killer lastly kills themselves in a murder-suicide. If only the parents are killed, the case may also be referred to as a parricide. Where all members of a family are killed, the crime may be referred to as family annihilation.
Jonathan Simon is an American academic who is the Lance Robbins Professor of Criminal Justice Law and former Associate Dean of the Jurisprudence and Social Policy Program at the UC Berkeley School of Law. Simon’s scholarship concerns the role of crime and criminal justice in governing contemporary societies, risk and the law, and the history of the interdisciplinary study of law.
The Macdonald triad is a set of three factors, the presence of any two of which are considered to be predictive of, or associated with, violent tendencies, particularly with relation to serial offenses. The triad was first proposed by psychiatrist J. M. Macdonald in "The Threat to Kill", a 1963 article in the American Journal of Psychiatry. Small-scale studies conducted by psychiatrists Daniel Hellman and Nathan Blackman, and then FBI agents John E. Douglas and Robert K. Ressler along with Ann Burgess, claimed substantial evidence for the association of these childhood patterns with later predatory behavior. Although it remains an influential and widely taught hypothesis, subsequent research has generally not validated this line of thinking.

There is a lack of consensus on how to define a mass shooting. Most terms define a minimum of three or four victims of gun violence in a short period of time, although an Australian study from 2006 required a minimum of five; and added a requirement that the victims actually died as opposed to being shot and injured but not necessarily killed.

Mass shootings are incidents involving multiple victims of firearm-related violence. The precise inclusion criteria are disputed, and there is no broadly accepted definition. One definition is an act of public firearm violence—excluding gang killings, domestic violence, or terrorist acts sponsored by an organization—in which a shooter kills at least four victims. Using this definition, one study found that nearly one-third of the world's public mass shootings between 1966 and 2012 occurred in the United States. Using a similar definition, The Washington Post records 163 mass shootings in the United States between 1967 and June 2019.
