Etymology
The modern English word "murder" descends from the
Proto-Indo-European ''*mŕ̥-trom'' which meant "killing", a noun derived from ''*mer-'' "to die".
Proto-Germanic in fact had two nouns derived from this word, later merging into the modern English noun: ''*murþrą'' "death, killing, murder" (directly from Proto-Indo-European''*mŕ̥-trom''), whence
Old English
Old English (, ), or Anglo-Saxon, is the earliest recorded form of the English language, spoken in England and southern and eastern Scotland in the early Middle Ages. It was brought to Great Britain by Anglo-Saxon settlement of Britain, Anglo ...
''morðor'' "secret or unlawful killing of a person, murder; mortal sin, crime; punishment, torment, misery"; and ''*murþrijô'' "murderer; homicide" (from the verb ''*murþrijaną'' "to murder"), giving Old English ''myrþra'' "homicide, murder; murderer". There was a third word for "murder" in Proto-Germanic, continuing Proto-Indo-European ''*mr̥tós'' "dead" (compare
Latin ''mors''), giving Proto-Germanic ''*murþą'' "death, killing, murder" and Old English ''morþ'' "death, crime, murder" (compare German ''Mord'').
The ''-d-'' first attested in
Middle English ''mordre, mourdre, murder, murdre'' could have been influenced by
Old French ''murdre'', itself derived from the Germanic noun via
Frankish ''*murþra'' (compare
Old High German ''murdreo, murdiro''), though the same sound development can be seen with ''burden'' (from ''burthen''). The alternative ''murther'' (attested up to the 19th century) springs directly from the Old English forms. Middle English ''mordre'' is a verb from Anglo-Saxon ''myrðrian'' from Proto-Germanic ''*murþrijaną'', or, according to the ''
Oxford English Dictionary'', from the noun.

convicted of murder in a court of law. After arrest, for example, journalists may instead write that the person was "arrested on suspicion of murder", or, after a prosecutor files charges, as an "accused murderer".
Opponents of abortion consider abortion a form of murder. In some countries, a fetus is a legal person who can be murdered, and killing a pregnant woman is considered a double homicide.

'' set out the
common law definition of murder, which by this definition occurs
The elements of common law murder are:
* unlawful
* killing
* through criminal act or omission
* of a human
* by another human
* with malice aforethought.
* ''Unlawful'' – This distinguishes murder from killings that are done within the boundaries of law, such as capital punishment, justified
self-defense, or the killing of enemy
combatant
Combatant is the legal status of an individual who has the right to engage in hostilities during an armed conflict. The legal definition of "combatant" is found at article 43(2) of Additional Protocol I (AP1) to the Geneva Conventions of 1949. It ...

collateral damage to
non-combatants during a war.
* ''Killing'' – At common law life ended with

– the total and irreversible cessation of blood circulation and respiration.
With advances in medical technology courts have adopted irreversible cessation of all brain function as marking the end of life.
* ''Criminal act or omission'' – Killing can be committed by an act or an
omission.
* ''Of a human'' – This element presents the issue of when life begins. At common law, a fetus was not a human being. Life began when the fetus passed through the vagina and took its first breath.
* ''By another human'' – In early common law,
suicide
Suicide is the act of intentionally causing one's own death. Mental disorders (including depression, bipolar disorder, schizophrenia, personality disorders, anxiety disorders), physical disorders (such as chronic fatigue syndrome), and s ...
was considered murder.
The requirement that the person killed be someone other than the perpetrator excluded suicide from the definition of murder.
* ''With malice aforethought'' – Originally ''
malice aforethought'' carried its everyday meaning – a deliberate and premeditated (prior intent) killing of another motivated by ill will. Murder necessarily required that an appreciable time pass between the formation and execution of the intent to kill. The courts broadened the scope of murder by eliminating the requirement of actual premeditation and deliberation as well as true malice. All that was required for malice aforethought to exist is that the perpetrator act with one of the four states of mind that constitutes "malice".
The four states of mind recognized as constituting "malice" are:
Under state of mind (i), intent to kill, the ''deadly weapon rule'' applies. Thus, if the defendant intentionally uses a
deadly weapon
A deadly weapon, sometimes dangerous weapon (although some jurisdictions differentiate between the two) or lethal weapon, is an item that can inflict mortal or great bodily harm. By statutory definition, certain items, especially firearms, are de ...
or instrument against the victim, such use authorizes a permissive inference of intent to kill. Examples of deadly weapons and instruments include but are not limited to guns, knives, deadly toxins or chemicals or gases and even vehicles when intentionally used to harm one or more victims.
Under state of mind (iii), an "abandoned and malignant heart", the killing must result from the defendant's conduct involving a reckless indifference to human life and a conscious disregard of an unreasonable risk of death or serious bodily injury. In Australian jurisdictions, the unreasonable risk must amount to a foreseen probability of death (or grievous bodily harm in most states), as opposed to possibility.
[; but the common law has been modified in NSW: .]
Under state of mind (iv), the felony-murder doctrine, the felony committed must be an inherently dangerous felony, such as burglary, arson, rape, robbery or kidnapping. Importantly, the underlying felony ''cannot'' be a
lesser included offense such as assault, otherwise all criminal homicides would be murder as all are felonies.
In Spanish criminal law, murder takes place when any of these requirements concur: Treachery (the use of means to avoid risk for the aggressor or to ensure that the crime goes unpunished), price or reward (financial gain) or viciousness (deliberately increasing the pain of the victim). After the last reform of the
Spanish Criminal Code
The Criminal Code is a law that codifies most criminal offences in Spain. The Code is established by an organic law, the Organic Law 10/1995, of 23 November, of the Criminal Code (''Ley Orgánica 10/1995, de 23 de noviembre, del Código Penal' ...
, in force since July 1, 2015, another circumstance that turns homicide into murder is the desire to facilitate the commission of another crime or to prevent it from being discovered.
As with most legal terms, the precise definition of murder varies between jurisdictions and is usually codified in some form of legislation. Even when the legal distinction between murder and manslaughter is clear, it is not unknown for a jury to find a murder defendant guilty of the lesser offense. The jury might sympathize with the defendant (e.g. in a
crime of passion, or in the case of a bullied victim who kills their tormentor), and the jury may wish to protect the defendant from a sentence of life imprisonment or execution.
Degrees of murder
Some jurisdictions divide murder by degrees. The distinction between first- and second-degree murder exists, for example, in
Canadian murder law and
U.S. murder law.
The most common division is between first- and second-degree murder. Generally, second-degree murder is common law murder, and first-degree is an aggravated form. The aggravating factors of first-degree murder depend on the jurisdiction, but may include a specific intent to kill, premeditation, or deliberation. In some, murders committed by acts such as
strangulation,
poisoning, or
lying in wait
In criminal law, lying in wait refers to the act of hiding and waiting for an individual with the intent to kill or inflict serious bodily harm to that person. Because lying in wait involves premeditation, some jurisdictions have established that ...
are also treated as first-degree murder. A few states in the U.S. further distinguish
third-degree murder, but they differ significantly in which kinds of murders they classify as second-degree versus third-degree. For example, Minnesota defines third-degree murder as
depraved-heart murder, whereas Florida defines third-degree murder as
felony murder
The rule of felony murder is a legal doctrine in some common law jurisdictions that broadens the crime of murder: when someone is killed (regardless of intent to kill) in the commission of a dangerous or enumerated crime (called a felony in s ...
(except when the underlying felony is specifically listed in the definition of first-degree murder).
Some jurisdictions also distinguish premeditated murder. This is the
crime of wrongfully and intentionally causing the death of another human being (also known as murder) after rationally considering the timing or method of doing so, in order to either increase the likelihood of success, or to evade detection or apprehension. State laws in the United States vary as to definitions of "premeditation". In some states, premeditation may be construed as taking place mere seconds before the murder. Premeditated murder is one of the most serious forms of homicide, and is punished more severely than manslaughter or other types of homicide, often with a
life sentence without the possibility of
parole, or in some countries, the
death penalty
Capital punishment, also known as the death penalty, is the state-sanctioned practice of deliberately killing a person as a punishment for an actual or supposed crime, usually following an authorized, rule-governed process to conclude that t ...
. In the U.S,
federal law () criminalizes premeditated murder, felony murder and second-degree murder committed under situations where federal jurisdiction applies. In Canada, the
criminal code classifies murder as either first- or second-degree. The former type of murder is often called premeditated murder, although premeditation is not the only way murder can be classified as first-degree.
Common law
According to Blackstone, English
common law identified murder as a ''public wrong''. According to common law, murder is considered to be ''
malum in se'', that is, an act which is evil within itself. An act such as murder is wrong or evil by its very nature, and it is the very nature of the act which does not require any specific detailing or definition in the law to consider murder a crime.
Some jurisdictions still take a common law view of murder. In such jurisdictions, what is considered to be murder is defined by
precedent case law or previous decisions of the courts of law. However, although the common law is by nature flexible and adaptable, in the interests both of certainty and of securing convictions, most common law jurisdictions have
codified their criminal law and now have statutory definitions of murder.
Exclusions
General
Although laws vary by country, there are circumstances of exclusion that are common in many legal systems.
* The killing of enemy combatants who have not surrendered, when committed by lawful combatants in accordance with lawful orders in war, is generally not considered murder. Illicit killings within a war may constitute murder or homicidal
war crimes; see
Laws of war.
*
Self-defense: acting in self-defense or in defense of another person is generally accepted as legal justification for killing a person in situations that would otherwise have been murder. However, a self-defense killing might be considered manslaughter if the killer established control of the situation before the killing took place. In the case of self-defense, it is called a "justifiable homicide".
* Unlawful killings without malice or intent are considered manslaughter.
* In many common law countries,
provocation is a partial defense to a charge of murder which acts by converting what would otherwise have been murder into manslaughter (this is voluntary manslaughter, which is more severe than involuntary manslaughter).
* Accidental killings are considered homicides. Depending on the circumstances, these may or may not be considered criminal offenses; they are often considered manslaughter.
* Suicide does not constitute murder in most societies. Assisting a suicide, however, may be considered murder in some circumstances.

* In some countries, the killing of a woman or girl in specific circumstances (e.g., when she commits
adultery and is killed by her husband or other family members, known as
honor killing) is not considered murder.
* In the United States, in some states and in federal jurisdiction, a killing by a police officer is excluded from prosecution if the officer believes they are being threatened with deadly force by the victim. This may include such actions by the victim as reaching into a glove compartment or pocket for license and registration, if the officer thinks that the victim might be reaching for a gun.
Victim
All jurisdictions require that the victim be a natural person; that is, a human being who was still alive before being murdered. In other words, under the law one cannot murder a
corpse, a corporation, a non-human animal, or any other non-human organism such as a plant or bacterium.

in his dissent, because women carrying nonviable fetuses may not be visibly pregnant, it may be possible for a defendant to be convicted of intentionally murdering a person they did not know existed.
Mitigating circumstances
Some countries allow conditions that "affect the balance of the mind" to be regarded as
mitigating circumstances. This means that a person may be found guilty of "manslaughter" on the basis of "diminished responsibility" rather than being found guilty of murder, if it can be proved that the killer was suffering from a condition that affected their judgment at the time.
Depression,
post-traumatic stress disorder and medication
side-effects are examples of conditions that may be taken into account when assessing responsibility.
Insanity
Mental disorder may apply to a wide range of disorders including
psychosis caused by
schizophrenia and
dementia, and excuse the person from the need to undergo the stress of a trial as to liability. Usually,
sociopathy and other
personality disorders are not legally considered insanity. In some jurisdictions, following the pre-trial hearing to determine the extent of the disorder, the defense of "not guilty by reason of insanity" may be used to get a not guilty verdict. This defense has two elements:

infanticide
Infanticide (or infant homicide) is the intentional killing of infants or offspring. Infanticide was a widespread practice throughout human history that was mainly used to dispose of unwanted children, its main purpose is the prevention of reso ...
. According to Susan Friedman, "Two dozen nations have infanticide laws that decrease the penalty for mothers who kill their children of up to one year of age. The United States does not have such a law, but mentally ill mothers may plead not guilty by reason of insanity." In the
law of the Republic of Ireland, infanticide was made a separate crime from murder in 1949, applicable for the mother of a baby under one year old where "the balance of her mind was disturbed by reason of her not having fully recovered from the effect of giving birth to the child or by reason of the effect of lactation consequent upon the birth of the child". Since independence, death sentences for murder in such cases had always been
commuted;
the new act was intended "to eliminate all the terrible ritual of the
black cap and the solemn words of the judge pronouncing sentence of death in those cases ... where it is clear to the Court and to everybody, except perhaps the unfortunate accused, that the sentence will never be carried out." In Russia, murder of a newborn child by the mother has been a separate crime since 1996.
Unintentional
For a killing to be considered murder in nine out of fifty states in the US, there normally needs to be an element of intent. A defendant may argue that they took precautions not to kill, that the death could not have been anticipated, or was unavoidable. As a general rule,

killing, but manslaughter also includes criminally negligent (i.e. grossly negligent) homicide.
Unintentional killing that results from an involuntary action generally cannot constitute murder. After examining the evidence, a judge or jury (depending on the jurisdiction) would determine whether the killing was intentional or unintentional.
Diminished capacity

diminished capacity may be a defense. For example,

Felony murder rule
A legal
doctrine in some common law jurisdictions broadens the crime of murder: when an offender kills in the commission of a dangerous crime, (regardless of intent), he or she is guilty of murder. The felony murder rule is often justified by its supporters as a means of preventing dangerous felonies, but the case of
Ryan Holle shows it can be used very widely.

accused of murder is not guilty if the victim survives for longer than
one year and one day after the attack. This reflects the likelihood that if the victim dies, other factors will have contributed to the cause of death, breaking the chain of
causation; and also means that the responsible person does not have a charge of murder "hanging over their head indefinitely". Subject to any
statute of limitations, the accused could still be charged with an offense reflecting the seriousness of the initial assault.
With advances in modern medicine, most countries have abandoned a fixed time period and test causation on the facts of the case. This is known as "delayed death" and cases where this was applied or was attempted to be applied go back to at least 1966.
In England and Wales, the "year-and-a-day rule" was abolished by the
Law Reform (Year and a Day Rule) Act 1996. However, if death occurs three years or more after the original attack then prosecution can take place only with the
attorney-general's approval.
In the United States, many jurisdictions have abolished the rule as well.
Abolition of the rule has been accomplished by enactment of statutory criminal codes, which had the effect of displacing the common-law definitions of crimes and corresponding defenses. In 2001 the
Supreme Court of the United States

held that retroactive application of a state supreme court decision abolishing the year-and-a-day rule did not violate the
Ex Post Facto Clause of
Article I of the United States Constitution.
The potential effect of fully abolishing the rule can be seen in the case of 74-year-old William Barnes, charged with the murder of a Philadelphia police officer Walter T. Barclay Jr., who he had shot nearly 41 years previously. Barnes had served 16 years in prison for attempting to murder Barkley, but when the policeman died on August 19, 2007, this was alleged to be from complications of the wounds suffered from the shooting – and Barnes was charged with his murder. He was acquitted on May 24, 2010.

Incidence
The
World Health Organization reported in October 2002 that a person is murdered every 60 seconds. An estimated 520,000 people were murdered in 2000 around the globe. Another study estimated the worldwide murder rate at 456,300 in 2010 with a 35% increase since 1990. Two-fifths of them were young people between the ages of 10 and 29 who were killed by other young people. Because murder is the least likely crime to go unreported, statistics of murder are seen as a
bellwether of overall crime rates.
Murder rates vary greatly among countries and societies around the world. In the
Western world, murder rates in most countries have declined significantly during the 20th century and are now between 1 and 4 cases per 100,000 people per year.
Latin America and the Caribbean, the region with the highest murder rate in the world, experienced more than 2.5 million murders between 2000 and 2017.
Murder rates by varies countries
Murder rates in jurisdictions such as Japan, Singapore,
Hong Kong, Iceland, Switzerland, Italy, Spain and Germany are among the lowest in the world, around 0.3–1 cases per 100,000 people per year; the rate of the United States is among the highest of
developed countries, around 4.5 in 2014, with rates in larger cities sometimes over 40 per 100,000. The top ten highest murder rates are in Honduras (91.6 per 100,000), El Salvador, Ivory Coast, Venezuela, Belize, Jamaica,

The following absolute murder counts per-country are not comparable because they are not adjusted by each country's total population. Nonetheless, they are included here for reference, with 2010 used as the base year (they may or may not include justifiable homicide, depending on the jurisdiction). There were 52,260 murders in Brazil, consecutively elevating the record set in 2009. Over half a million people were shot to death in Brazil between 1979 and 2003. 33,335 murder cases were registered across India, approximately 17,000 murders in Colombia (the murder rate was 38 per 100,000 people, in 2008 murders went down to 15,000), approximately 16,000 murders in South Africa, approximately 15,000 murders in the United States, approximately 26,000 murders in Mexico, about 8,000 murders committed in Russia, approximately 13,000 murders in Venezuela, approximately 4,000 murders in El Salvador, approximately 1,400 murders in Jamaica, approximately 550 murders in Canada and approximately 470 murders in Trinidad and Tobago. Pakistan reported 12,580 murders.
Murder in the United States
In the United States, 666,160 people were killed between 1960 and 1996. Approximately 90% of murders in the US are committed by males. Between 1976 and 2005, 23.5% of all murder victims and 64.8% of victims murdered by intimate partners were female. For women in the US, homicide is the leading cause of death in the workplace.

's Supplementary Homicide Report indicated that nearly half of the 14,990 murder victims that year were Black (7421). In the year 2007, there were 3,221 black victims and 3,587 white victims of non-negligent homicides. While 2,905 of the black victims were killed by a black offender, 2,918 of the white victims were killed by white offenders. There were 566 white victims of black offenders and 245 black victims of white offenders. The "white" category in the
Uniform Crime Reports (UCR) includes non-black
Hispanics.
Murder demographics are affected by the improvement of
trauma care, which has resulted in reduced lethality of violent assaults – thus the murder rate may not necessarily indicate the overall level of social violence.

. Using properly filtered data, it is possible to make the case for or against either of these issues. For example, one could look at murder rates in the United States from 1950 to 2000, and notice that those rates went up sharply shortly after a
moratorium on death sentences was effectively imposed in the late 1960s. This fact has been used to argue that capital punishment serves as a deterrent and, as such, it is morally justified. Capital punishment opponents frequently counter that the United States has much higher murder rates than Canada and most
European Union countries, although all those countries have abolished the death penalty. Overall, the global pattern is
too complex, and on average, the influence of both these factors may not be significant and could be more social, economic, and cultural.

History of murder rates
According to scholar Pieter Spierenburg
homicide rates
The list of countries by UNODC homicide rate is typically expressed in units of deaths per 100,000 individuals per year. A mortality rate of 30 (out of 100,000) in a population of 100,000 would mean 30 deaths per year in that entire population, or ...

New Yorker, November 9, 2009
In the United States, murder rates have been higher and have fluctuated. They fell below 2 per 100,000 by 1900, rose during the first half of the century, dropped in the years following World War II, and bottomed out at 4.0 in 1957 before rising again. The rate stayed in 9 to 10 range most of the period from 1972 to 1994, before falling to 5 in present times.
The increase since 1957 would have been even greater if not for the significant improvements in medical techniques and emergency response times, which mean that more and more attempted homicide victims survive. According to one estimate, if the lethality levels of criminal assaults of 1964 still applied in 1993, the country would have seen the murder rate of around 26 per 100,000, almost triple the actually observed rate of 9.5 per 100,000.
A similar, but less pronounced pattern has been seen in major European countries as well. The murder rate in the United Kingdom fell to 1 per 100,000 by the beginning of the 20th century and as low as 0.62 per 100,000 in 1960, and was at 1.28 per 100,000 . The murder rate in France (excluding Corsica) bottomed out after World War II at less than 0.4 per 100,000, quadrupling to 1.6 per 100,000 since then.
The specific factors driving this dynamics in murder rates are complex and not universally agreed upon. Much of the raise in the U.S. murder rate during the first half of the 20th century is generally thought to be attributed to gang violence associated with
Prohibition. Since most murders are committed by young males, the near simultaneous low in the murder rates of major developed countries circa 1960 can be attributed to low birth rates during the Great Depression and World War II. Causes of further moves are more controversial. Some of the more exotic factors claimed to affect murder rates include the availability of abortion and the likelihood of chronic exposure to
lead during childhood (due to the use of leaded paint in houses and
tetraethyllead as a gasoline additive in internal combustion engines).
Investigation
The success rate of
criminal investigations into murders (the
clearance rate) tends to be relatively high for murder compared to other crimes, due to its seriousness. In the United States, the clearance rate was 62.6% in 2004.
