Homicide Law

What is Homicide Law?

Homicide law is an umbrella term used to describe a number of offenses that can be charged when the defendant has wrongfully caused the death of another human being. The specific homicide offense charged in a given case will depend upon the defendant’s mental state and subjective intentions at the time the crime was committed. Some homicides occur unintentionally, as the result of extremely reckless behavior. Others are committed following a period of deliberation and forethought by the defendant.

These factors can lead to vastly different sentences following a conviction. A lenient sentence may be appropriate in cases involving accidental death. Conversely, premeditated killings are punishable by life in prison, or by the death penalty in states that have not abolished it. Homicide cases are among the most serious of all criminal proceedings. Those accused of any type of homicide crime should seek immediate assistance from a qualified criminal defense attorney.

Statutory Murder Classifications

Historically, crimes such as homicide were a matter of common law, meaning they were created and defined through an evolving body of court decisions. In modern times, homicide laws are established by state legislatures and set forth in penal codes. The most egregious of these statutory offenses are typically labeled murder in the first degree, and murder in the second degree.

First degree murder is unique in that it requires that the defendant acted deliberately, dispassionately, and in a premeditated manner. For at least a brief moment before the killing took place, the defendant must have pondered the matter, and then consciously decided to commit the act. Second degree murder, on the other hand, does not require the element of premeditation. Besides that, the two crimes are identical.

The distinction between first and second degree murder will control which defenses are available. For example, because first degree murder requires that the defendant had a pre-existing intent to commit the crime, the defense of intoxication may be invoked. That is to say, if the defendant was too intoxicated to premeditate on the act, then the element of intent is missing, and the defendant cannot be convicted. Second degree murder does not require a specific mental state, so intoxication is not available as a defense.

Manslaughter Offenses

Criminal justice systems have always recognized some form of reduced culpability for killings that are committed in the “heat of passion.” Modern penal codes define the crime of voluntary manslaughter as murder provoked by a sudden and intense passion that caused the defendant to lose control. The events that brought about the emotional reaction must have been of a type that would lead a reasonable person to lose control. Thus, if the defendant reacted irrationally, the reduced charge of voluntary manslaughter is not appropriate.

Whether a murder charge will be reduced to voluntary manslaughter can also depend upon the amount of time that passed between the provocation and the killing. The longer this cooling off period, the less likely the killing will qualify as voluntary manslaughter.

The related crime of involuntary manslaughter differs greatly from both voluntary manslaughter and murder, in that these killings are not committed on purpose. Rather, they are a result of criminal negligence by the defendant. To sustain a conviction for involuntary manslaughter, it must have been foreseeable that the defendant’s extreme carelessness could lead to the death of the victim.

Death Caused in the Commission of a Felony

A large percentage of homicide convictions are based on killings that occur while defendants are engaged in the commission of a separate crime. Often referred to as “felony murder,” these homicides are based on the idea that a person who commits a dangerous crime should be held responsible for the resulting collateral damage. Nevertheless, the law places some limits on this type of criminal liability.

For example, to be guilty of felony murder, the underlying crime must be a serious one. Penal codes contain lists of these crimes. They usually include robbery, arson, rape, and other violent felonies. The government must also prove the defendant is guilty of the underlying crime. Therefore, if the jury finds the evidence is insufficient to convict the defendant of the underlying crime, the defendant must also be acquitted of felony murder.

There are also restrictions on whose death can form the basis of a felony murder charge. The killing of bystanders, police officers, and other innocent victims will satisfy these statutes, but the killing of a co-conspirator generally will not. Finally, once the underlying crime (and the defendant’s flight from the crime scene) is complete, liability for felony murder homicide ends. Any subsequent deaths cannot be charged under this theory.

Homicide Defense Requires a Skilled Attorney

  • Euthanasia, Physician Assisted Suicide, Mercy Killing - Justifiable Homicide

    Assisted suicide laws around the world are clear in some nations but unclear – if they exist at all – in others. Just because a country has not defined its criminal code on this specific action does not mean all assisters will go free. It is a complicated state of affairs. A great many people instinctively feel that suicide and assisted suicide are such individual acts of freedom and free will that they assume there are no legal prohibitions. This fallacy has brought many people into trouble with the law. While suicide is no longer a crime – and where it is because of a failure to update the law it is not enforced – assistance remains a crime almost everywhere by some statute or other.

In some states, legislation has increased the criminal penalties for crimes involving pregnant women. These laws have focused on the harm done to a pregnant woman and the subsequent loss of her pregnancy, but not on the rights of the fetus.
