Involuntary manslaughter is a criminal offense defined as the unintentional killing (homicide) of another person as a result of criminal negligence, recklessness, or during the commission of a misdemeanor (driving while intoxicated), infraction (speeding), or a felony crime that was not inherently dangerous. Involuntary manslaughter is usually a felony offense and often includes significant jail or prison time as potential punishment.

Involuntary manslaughter laws vary from state to state and are generally located in a state’s statutes—often in the penal or criminal code.

In Kentucky, involuntary manslaughter is referred to as 'Manslaughter in the Second Degree' and is codified under Kentucky Revised Statutes (KRS) 507.040. This statute defines the offense as the unintentional killing of another person as a result of a person's wanton or reckless behavior. It does not require an intent to cause death or injury, but it does require conduct that shows a disregard for human life or an awareness of an unjustifiable risk that death or serious physical injury could occur. Manslaughter in the Second Degree is classified as a Class C felony in Kentucky, which can result in a prison sentence ranging from 5 to 10 years. The specific circumstances of the offense, such as committing manslaughter while driving under the influence, can influence the severity of the punishment. It is important for individuals facing such charges to consult with an attorney who is knowledgeable in Kentucky's criminal law to understand the charges and potential defenses.
