Manslaughter
Manslaughter is a serious felony involving the unlawful killing of a person but is considered less severe than murder. It is characterized by a lack of premeditation, often occurring in moments of heightened emotional distress, referred to as "heat of passion." There are two primary categories of manslaughter: voluntary and involuntary. Voluntary manslaughter, or first-degree manslaughter, involves killings driven by intense emotions such as anger or fear, while involuntary manslaughter, sometimes termed negligent homicide, involves deaths resulting from reckless or dangerous behavior without intent to kill. The penalties for manslaughter can vary significantly across different states in the U.S., ranging from probation for involuntary manslaughter to lengthy prison sentences for voluntary manslaughter. Importantly, those convicted of manslaughter cannot face the death penalty, reflecting its distinction from murder charges. Understanding these classifications and penalties can provide insight into the legal ramifications of involuntary and impulsive actions resulting in loss of life.

Manslaughter
SIGNIFICANCE: While manslaughter is considered a felony and a very serious offense involving the unlawful killing of a human being, it is a lesser included offense of murder and is thus punished less severely.
Manslaughter generally is the unplanned or sudden killing of a person. In the United States, persons who commit manslaughter cannot be punished by the death penalty. Manslaughter is distinguishable from the more serious offenses of first and second-degree murder by the reduced degree of intent with which the killing is done. Manslaughter is a killing done suddenly, without planning or “premeditation,” which is the hallmark of first-degree murder. It is often committed in a highly emotional state without calm or cool reflection, described in the law as “heat of passion.” Although a person who commits manslaughter does not plan or premeditate the offense and does not coolly or calmly reflect or deliberate upon it, manslaughter is not an accidental killing. Thus, it is unlawful.
There are two types of manslaughter: voluntary and involuntary. Some states call these crimes manslaughter in the first degree and manslaughter in the second degree. Voluntary (or first-degree) manslaughter is the more serious of the two offenses. Voluntary manslaughter is a homicide that occurs through impassioned actions, such as anger, jealousy, or fear. When these emotions are sufficiently heightened, a person is said to be unable to deliberate or reflect upon the act of killing. A voluntary manslaughter committed in a calm and thoughtful frame of mind would be a murder.
Involuntary manslaughter is a homicide that occurs through very reckless or dangerous actions, which may even be minor crimes such as careless driving. In some U.S. states involuntary manslaughter is called “negligent homicide.” Involuntary manslaughter requires only a serious lack of care concerning a dangerous or possibly dangerous situation that causes a death. A typical example of involuntary manslaughter is an unintended death that occurs because someone committed a very risky or dangerous act, such as drag racing on a public street or leaving a vicious dog inadequately fenced in. Some states have defined a special type of manslaughter involving the reckless use of a motor vehicle that causes death. This offense is variously called “vehicular manslaughter,” “vehicular homicide,” or simply manslaughter. In February 2024, a jury convicted a mother of involuntary manslaughter in relation to her teenager, who committed a mass shooting. The instance was the first time a parent was held responsible for a child's violent crime via a charge of manslaughter. Penalties for manslaughter in the United States vary between states but generally can range from probation or short periods in jail for involuntary manslaughter to long terms of imprisonment of more than ten years for voluntary manslaughter.
