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 Oklahoma, involuntary manslaughter is addressed under the state's penal code, specifically in Title 21 of the Oklahoma Statutes. The offense is defined as the unintentional killing of another person that occurs either due to criminal negligence or during the commission of a misdemeanor or a low-level felony that is not inherently dangerous. This could include actions such as reckless driving or operating a vehicle under the influence of alcohol or drugs. Involuntary manslaughter in Oklahoma is considered a felony, and those convicted may face substantial penalties, including prison time, fines, and probation. The exact punishment can vary based on the circumstances of the case and the defendant's criminal history. It is important for individuals facing such charges to consult with an attorney to understand the specific implications of the law and the potential defenses that may be available to them.
