Manslaughter is the unlawful killing or homicide of a human being without the premeditation or malice (malice aforethought) required for the criminal offense of murder. Many states have two types of manslaughter: (1) voluntary manslaughter—the defendant intended to kill the victim, but did so in self-defense, or in the heat of passion and without premeditation, or the defendant was insane and did not understand that the killing was wrong; and (2) involuntary manslaughter—the defendant negligently or recklessly caused the death of another person—such as when a person is intoxicated while operating a motor vehicle and causes an accident that results in the death of another person.
Some states do not have separate criminal offenses for voluntary and involuntary manslaughter—these states may have the offense of manslaughter and identify certain aggravating factors that may enhance the penalties upon a conviction for manslaughter. Manslaughter is a felony offense and may be punished by a lengthy prison term. Manslaughter laws are generally located in a state's statutes—often in the penal or criminal code.
In Texas, manslaughter is considered a second-degree felony under Texas Penal Code Section 19.04. The state recognizes a single general category of manslaughter, which is defined as recklessly causing the death of an individual. Texas does not formally distinguish between voluntary and involuntary manslaughter in its statutes. However, there is a related offense called 'criminally negligent homicide' (Texas Penal Code Section 19.05) which is a state jail felony and involves causing a death through criminal negligence, which is a lesser degree of culpability than the recklessness required for manslaughter. Manslaughter in Texas is punishable by imprisonment for any term of not more than 20 years or less than 2 years, in addition to possible fines. It's important to note that Texas also recognizes the 'heat of passion' defense under certain circumstances, which can reduce a murder charge to manslaughter if the defendant acted immediately upon a provocation that would cause an ordinary person to become temporarily impassioned.
