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 Kansas, involuntary manslaughter is addressed under Kansas Statutes Annotated (K.S.A.) 21-5405. It is defined as the unintentional killing of a human being committed: (1) recklessly, (2) in the commission of a lawful act in an unlawful manner, or (3) during the commission of a misdemeanor or a low-level felony that is not considered inherently dangerous. Involuntary manslaughter is considered a severity level 5, person felony in Kansas. The penalties for involuntary manslaughter can include a prison sentence, fines, and probation, depending on the circumstances of the case and the defendant's criminal history. The specific sentencing guidelines are outlined in the Kansas Sentencing Guidelines, which take into account the severity of the offense and the criminal history of the offender. It is important for individuals facing such charges to consult with an attorney to understand the potential legal consequences and to navigate the complexities of the legal system.
