Murder Law



Find a Law Firm:

Murder is defined as the unlawful and malicious or premeditated killing of one human being by another as well as any killing done while committing some other felony such as rape or robbery. Not all States have adopted the Model Penal Code to classify murder, however, it serves and continues to serve as a basis for the replacement of existing criminal codes in over two-thirds of US states.

Murder Law - US

  • (DPIC) - Federal Laws Providing for the Death Penalty

    Although not listed by BJS, the following offenses are also punishable by death under the federal statute, though it is not clear that the death penalty would be constitutional for these offenses under Kennedy v. Louisiana (2008) since they do not require a murder: -Trafficking in large quantities of drugs (18 U.S.C. 3591(b)) -Attempting, authorizing or advising the killing of any officer, juror,or witness in cases involving a Continuing Criminal Enterprise, regardless of whether such killing actually occurs. (18 U.S.C. 3591(b)(2)).

  • Bureau of Justice Statistics (BJS) - Violent Crimes

    Violent crime includes murder, rape and sexual assault, robbery, and assault. Information about murder is obtained on a yearly basis from the FBI’s Uniform Crime Reports. There are two measures for non-fatal violence—the Uniform Crime Reports (UCR) and the National Crime Victimization Survey (NCVS). NCVS measures rape/sexual assault, robbery, and aggravated and simple assault.

  • First Degree Murder vs Second Degree Murder

    In general, 1st degree murder is grave murder planned and committed in a cruel way against one or more persons, under special circumstances. The special circumstances include accompaniment of other offenses such as, kidnapping, hijacking, robbery, with an intention of financial gain, assault on pregnant women or government officials on public duty, or involving extreme torture. This is considered more serious if the person committing the offence has committed such a crime before. 2nd degree murder, in general, is premeditated murder against spouse or relatives, or due to personal gain and interest, without the presence of special circumstances. It is considered slightly less grave than first degree murder. In some countries second degree murder is also defined as unplanned killing due to an accident.

  • Laci and Conner's Law - Unborn Victims of Violence Act

    In a landmark right-to-life victory, President George W. Bush on April 1 signed into law the Unborn Victims of Violence Act, also known as "Laci and Conner's Law."

  • Matthew Shepard Hate Crimes Prevention Act

    This legislation seeks to expand upon 1969 U.S. federal hate-crime law by extending its scope towards bodily crimes motivated by a victim’s actual or perceived gender, sexual orientation, gender identity, or disability, in addition to the current provisions of bodily crimes motivated by a victim's actual or perceived race, color, religion, and national origin. It would also codify and expand the funding and investigative capabilities of federal officials for aiding their local counterparts.

  • Murder - Definition

    Murder, as defined in common law countries, is the unlawful killing of another human being with intent (or malice aforethought), and generally this state of mind distinguishes murder from other forms of unlawful homicide (such as manslaughter). As the loss of a human being inflicts enormous grief upon the individuals close to the victim, as well as the fact that the commission of a murder deprives the victim of their worldly existence, most societies both present and in antiquity have considered it a most serious crime worthy of the harshest of punishment. A person convicted murder is typically given a life sentence or even the death penalty for such an act.

  • Murder - Overview

    Murder occurs when one human being unlawfully kills another human being. The precise legal definition of murder varies by jurisdiction. Most states distinguish between different degrees of murder. Some other states base their murder laws on the Model Penal Code.

  • Serial Killers vs Mass Murderers

    First, mass murderers are generally apprehended or killed by police, commit suicide, or turn themselves in to authorities. Serial killers, by contrast, usually make special efforts to elude detection. Indeed, they may continue to kill for weeks, months, and often years before they are found and stopped-if they are found at all. In the case of the California Zodiac killer, the homicides appeared to have stopped, but an offender was never apprehended for those crimes.

  • The Model Penal Code - Murder

    The Model Penal Code moved away from the traditional common law approach to murder. A key feature of the MPC is its use of standardized mens rea (criminal mind) terms to determine levels of mental states, just as homicide is considered more severe if done intentionally rather than accidentally. These terms are (in descending order) "purposefully", "knowingly," "recklessly", and "negligently", with a fifth state of "strict liability".

  • US Sentencing Commission - Sentencing Guidelines for Offenses Against the Person

    Chapter Two pertains to offense conduct. The chapter is organized by offenses and divided into parts and related sections that may cover one statute or many. Each offense has a corresponding base offense level and may have one or more specific offense characteristics that adjust the offense level upward or downward. Certain factors relevant to the offense that are not covered in specific guidelines in Chapter Two are set forth in Chapter Three, Parts A (Victim-Related Adjustments), B (Role in the Offense), and C (Obstruction); Chapter Four, Part B (Career Offenders and Criminal Livelihood); and Chapter Five, Part K (Departures).

  • Violent Crime Control and Law Enforcement Act of 1994

    The Violent Crime Control and Law Enforcement Act of 1994 represents the bipartisan product of six years of hard work. It is the largest crime bill in the history of the country and will provide for 100,000 new police officers, $9.7 billion in funding for prisons and $6.1 billion in funding for prevention programs which were designed with significant input from experienced police officers. The Act also significantly expands the government's ability to deal with problems caused by criminal aliens.
