Involuntary manslaughter is a serious criminal charge in New Mexico for an unintentional killing. This offense occurs without premeditation or the intent to cause death, distinguishing it from murder, and the law defines specific actions that can lead to this charge, along with significant penalties.
Defining Involuntary Manslaughter Under New Mexico Law
Under New Mexico Statutes Annotated § 30-2-3, involuntary manslaughter is defined as the unlawful killing of a human being without malice. The statute outlines two specific pathways by which this crime can be committed. A person can face these charges for a death that occurs while they are committing an unlawful act that is not a felony, such as a misdemeanor. The second way is by causing a death during a lawful act that might produce death, but doing so in an unlawful manner or “without due caution and circumspection.” This phrase points to the legal concept of criminal negligence. It involves a reckless disregard for the safety of others by failing to recognize an obvious risk that a reasonable person would have noticed.
Examples of Actions Leading to Involuntary Manslaughter Charges
For the first type, where a death results from a non-felony unlawful act, a common example involves a simple assault or battery. If two people get into a minor physical altercation and one person pushes the other, causing them to fall, hit their head, and die, the person who initiated the push could be charged with involuntary manslaughter.
For the second type, involving a lawful act performed with criminal negligence, one scenario is the grossly negligent mishandling of a firearm. If an individual is cleaning a loaded gun they believed was unloaded and it discharges, killing someone, their failure to follow basic firearm safety rules could be seen as acting without due caution and circumspection. Another example is leaving a young child unattended in a hot car, leading to the child’s death.
These examples highlight that the core of the offense is not an intent to harm. Instead, it is a death caused by either a lesser crime or by engaging in an otherwise normal activity with a degree of recklessness that the law deems unacceptable.
Penalties and Sentencing for Involuntary Manslaughter
The offense is classified as a fourth-degree felony under the state’s criminal code.1Justia Law. New Mexico Statutes Section 30-2-3 (2024) – Manslaughter This classification dictates the range of punishments a judge can impose.
The law provides a presumptive prison sentence of 18 months for a fourth-degree felony, and a conviction can also result in a fine of up to $5,000.2Justia Law. New Mexico Statutes Section 31-18-15 (2024) – Sentencing authority; noncapital felonies; basic sentences and fines The court also has the discretion to impose a period of probation, either in lieu of or following a prison sentence. Other court-ordered sanctions may be included, such as requirements to pay restitution to the victim’s family to cover expenses like funeral costs or counseling.3Justia Law. New Mexico Statutes Section 31-17-1 (2024) – Victim restitution The court might also mandate that the convicted individual attend specific counseling or treatment programs.
Involuntary Manslaughter Involving a Vehicle
When a death occurs as a result of a person’s driving, the situation can sometimes fall under the general involuntary manslaughter statute. While New Mexico has a specific “homicide by vehicle” law that applies to cases involving driving while intoxicated or reckless driving, involuntary manslaughter may be charged in other circumstances.4Justia Law. New Mexico Statutes Section 66-8-101 (2024) – Homicide by vehicle; great bodily harm by vehicle If a death results from criminal negligence that doesn’t meet the elements of the vehicular homicide statute, a charge of involuntary manslaughter is possible.
For example, a driver who knowingly operates a vehicle with a severe mechanical failure, like faulty brakes, and causes a fatal accident could be prosecuted. In such a case, the act of driving is lawful, but doing so with a known, life-threatening defect could be seen as criminally negligent. This application of the law ensures a legal framework exists to address fatal incidents caused by grossly negligent driving that may not fit into more specific vehicular homicide definitions.
