Murder is the unlawful killing of another human without justification or valid excuse, especially the unlawful killing of another human with malice aforethought. This state of mind may, depending upon the jurisdiction, distinguish murder from other forms of unlawful homicide, such as manslaughter. Manslaughter is killing committed in the absence of malice, brought about by reasonable provocation, or diminished capacity. Involuntary manslaughter, where it is recognized, is a killing that lacks all but the most attenuated guilty intent, recklessness.
Life imprisonment is any sentence of imprisonment for a crime under which convicted people are to remain in prison for the rest of their natural lives or indefinitely until pardoned, paroled, or otherwise commuted to a fixed term. Crimes for which, in some countries, a person could receive this sentence include murder, torture, terrorism, child abuse resulting in death, rape, espionage, treason, drug trafficking, drug possession, human trafficking, severe fraud and financial crimes, aggravated criminal damage, arson, kidnapping, burglary, and robbery, piracy, aircraft hijacking, and genocide, crimes against humanity, war crimes or any three felonies in case of three-strikes law. Life imprisonment can also be imposed, in certain countries, for traffic offences causing death. Life imprisonment is not used in all countries; Portugal was the first country to abolish life imprisonment, in 1884.
Capital punishment is a legal punishment in Louisiana.
Vehicular homicide is a crime that involves the death of a person other than the driver as a result of either criminally negligent or murderous operation of a motor vehicle.
In the United States, habitual offender laws have been implemented since at least 1952, and are part of the United States Justice Department's Anti-Violence Strategy. These laws require a person who is convicted of an offense and who has one or two other previous serious convictions to serve a mandatory life sentence in prison, with or without parole depending on the jurisdiction. The purpose of the laws is to drastically increase the punishment of those who continue to commit offenses after being convicted of one or two serious crimes.
In United States law, depraved-heart murder, also known as depraved-indifference murder, is a type of murder where an individual acts with a "depraved indifference" to human life and where such act results in a death, despite that individual not explicitly intending to kill. In a depraved-heart murder, defendants commit an act even though they know their act runs an unusually high risk of causing death or serious bodily harm to a person. If the risk of death or bodily harm is great enough, ignoring it demonstrates a "depraved indifference" to human life and the resulting death is considered to have been committed with malice aforethought. In some states, depraved-heart killings constitute second-degree murder, while in others, the act would be charged with "wanton murder," varying degrees of manslaughter, or third-degree murder.
Gregg v. Georgia, Proffitt v. Florida, Jurek v. Texas, Woodson v. North Carolina, and Roberts v. Louisiana, 428 U.S. 153 (1976), is a landmark decision of the U.S. Supreme Court. It reaffirmed the Court's acceptance of the use of the death penalty in the United States, upholding, in particular, the death sentence imposed on Troy Leon Gregg. The case is referred to by a leading scholar as the July 2 Cases, and elsewhere referred to by the lead case Gregg. The court set forth the two main features that capital sentencing procedures must employ in order to comply with the Eighth Amendment ban on "cruel and unusual punishments". The decision essentially ended the de facto moratorium on the death penalty imposed by the Court in its 1972 decision in Furman v. Georgia 408 U.S. 238 (1972).
Mandatory sentencing requires that offenders serve a predefined term for certain crimes, commonly serious and violent offenses. Judges are bound by law; these sentences are produced through the legislature, not the judicial system. They are instituted to expedite the sentencing process and limit the possibility of irregularity of outcomes due to judicial discretion. Mandatory sentences are typically given to people who are convicted of certain serious and/or violent crimes, and require a prison sentence. Mandatory sentencing laws vary across nations; they are more prevalent in common law jurisdictions because civil law jurisdictions usually prescribe minimum and maximum sentences for every type of crime in explicit laws.
In England and Wales, life imprisonment is a sentence that lasts until the death of the prisoner, although in most cases the prisoner will be eligible for early release after a minimum term set by the judge. In exceptional cases, however, a judge may impose a "whole life order", meaning that the offender is never considered for parole, although they may still be released on compassionate grounds at the discretion of the Home Secretary. Whole life orders are usually imposed for aggravated murder, and can only be imposed where the offender was at least 21 years old at the time of the offence being committed.
Coker v. Georgia, 433 U.S. 584 (1977), held that the death penalty for rape of an adult woman was grossly disproportionate and excessive punishment, and therefore unconstitutional under the Eighth Amendment to the U.S. Constitution. A few states continued to have child rape statutes that authorized the death penalty. In Kennedy v. Louisiana (2008), the court expanded Coker, ruling that the death penalty is unconstitutional in all cases that do not involve homicide or crimes against the State.
Murder is an offence under the common law of England and Wales. It is considered the most serious form of homicide, in which one person kills another with the intention to cause either death or serious injury unlawfully. The element of intentionality was originally termed malice aforethought, although it required neither malice nor premeditation. Baker, chapter 14 states that many killings done with a high degree of subjective recklessness were treated as murder from the 12th century right through until the 1974 decision in DPP v Hyam.
In the English law of homicide, manslaughter is a less serious offence than murder, the differential being between levels of fault based on the mens rea or by reason of a partial defence. In England and Wales, a common practice is to prefer a charge of murder, with the judge or defence able to introduce manslaughter as an option. The jury then decides whether the defendant is guilty or not guilty of either murder or manslaughter. On conviction for manslaughter, sentencing is at the judge's discretion, whereas a sentence of life imprisonment is mandatory on conviction for murder. Manslaughter may be either voluntary or involuntary, depending on whether the accused has the required mens rea for murder.
Manslaughter is a common law legal term for homicide considered by law as less culpable than murder. The distinction between murder and manslaughter is sometimes said to have first been made by the ancient Athenian lawmaker Draco in the 7th century BC.
Antti Olavi Taskinen is a Finnish double-murderer, who is responsible for the deaths of at least two men in Tampere and Heinola. He was sentenced to life in prison on May 31, 2006.
In the United States, life imprisonment is amongst the most severe punishments provided by law, depending on the state, and second only to the death penalty. According to a 2013 study, 1 of every 20,000 inhabitants of the U.S. were imprisoned for life as of 2012. Many U.S. states can release a convict on parole after a decade or more has passed, but in California, people sentenced to life imprisonment can normally apply for parole after seven years. The laws in the United States categorize life sentences as "determinate life sentences" or "indeterminate life sentences," the latter indicating the possibility of an abridged sentence, usually through the process of parole. For example, sentences of "15 years to life," "25 years to life," or "life with mercy" are called "indeterminate life sentences", while a sentence of "life without the possibility of parole" or "life without mercy" is called a "determinate life sentence". The potential for parole is not assured but discretionary, making it an indeterminate sentence. Even if a sentence explicitly denies the possibility of parole, government officials may have the power to grant an amnesty to reprieve, or to commute a sentence to time served.
In Germany, life imprisonment has an indeterminate length and is the most severe punishment that can be imposed. A person sentenced to life imprisonment may normally apply for parole after having served 15 years. If the parole court rejects the application, the inmate may reapply after a court determined blocking period no longer than two years. If the court has determined a "severe gravity of guilt" exists, parole is delayed for a non-specific period beyond 15 years.
The Portuguese Penal Code was adopted in 1982 and has been revised on several occasions, most recently in 2007. It devotes a whole chapter on "crimes against human life". In fact, the very first crime addressed on that code is murder.
In the United States, the law for murder varies by jurisdiction. In most US jurisdictions there is a hierarchy of acts, known collectively as homicide, of which first-degree murder and felony murder are the most serious, followed by second-degree murder and, in a few states, third-degree murder, followed by voluntary manslaughter and involuntary manslaughter which are not as serious, followed by reckless homicide and negligent homicide which are the least serious, and ending finally in justifiable homicide, which is not a crime. However, because there are at least 52 relevant jurisdictions, each with its own criminal code, this is a considerable simplification.
Graham v. Florida, 560 U.S. 48 (2010), was a decision by the Supreme Court of the United States holding that juvenile offenders cannot be sentenced to life imprisonment without parole for non-homicide offenses.
