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 Wyoming, involuntary manslaughter is addressed under Wyoming Statutes Title 6. Crimes and Offenses, specifically in Chapter 2 - Offenses Against the Person. Involuntary manslaughter in Wyoming is defined as the unlawful killing of a human being without malice, expressed or implied, and without any mixture of deliberation. It can occur either in the commission of an unlawful act not amounting to a felony, or in the commission of a lawful act which might produce death, in an unlawful manner, or without due caution and circumspection. This offense is typically classified as a felony, and the penalties can include imprisonment, fines, or both. The specific classification of the felony and the range of potential penalties 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 who can provide legal advice tailored to the specifics of their case.
