The Ultimate Guide to Criminally Negligent Homicide
What You Need to Know About Criminally Negligent Homicide in Texas
Criminally negligent homicide occurs when a person causes another’s death through criminal negligence—meaning they failed to perceive a substantial and unjustifiable risk that a reasonable person would have recognized. In Texas, this charge is the lowest level of culpable homicide, but it still carries serious felony consequences that can change your life forever.
Key Facts About Criminally Negligent Homicide:
- Legal Classification: State jail felony under Texas Penal Code § 19.05
- Prison Sentence: 180 days to 2 years in state jail
- Maximum Fine: Up to $10,000
- Mental State Required: Criminal negligence (failure to perceive risk), not intent to kill
- Key Difference from Manslaughter: Manslaughter requires recklessness (consciously disregarding a known risk), while criminally negligent homicide involves failing to perceive a risk.
- Common Examples: Fatal DWI accidents, leaving a child in a hot car, discharging a firearm negligently, driving with known dangerous vehicle defects
The line between a tragic accident and a crime is at the heart of every criminally negligent homicide case. The outcome depends on whether your actions were a “gross deviation” from what an ordinary person would do—a vague standard when you’re facing charges in Houston or Harris County.
These cases are emotionally profound because they typically involve no intent to harm. They arise from human error or a failure to appreciate danger that leads to the worst possible outcome. The legal system must decide if that failure rises to the level of criminal negligence, which is far more serious than ordinary carelessness.
I’m Herman Martinez, founder of The Martinez Law Firm in Houston. I’ve spent over 25 years on both sides of these cases—first as a Chief Prosecutor for the Harris County District Attorney’s Office and now as a defense attorney. This unique perspective shows me that winning often depends on how effectively your attorney challenges the prosecution’s claims about what you “should have known.”
Understanding Criminally Negligent Homicide in Texas
When someone dies because of another’s actions, Texas law must determine culpability. Criminally negligent homicide is the least severe homicide charge, but it’s a state jail felony with life-altering consequences.
What makes this charge unique is the lack of intent. The accused didn’t mean for anyone to die or even consciously take a known risk. Instead, they failed to see a danger that a reasonable person would have spotted. It is this failure—this blind spot—that the law deems criminal.
But how is this different from ordinary carelessness that might lead to a lawsuit? The answer is “gross deviation from the standard of care.” Texas law doesn’t punish every mistake. Criminal negligence requires a profound failure to recognize an obvious, substantial danger.
What is the legal definition of criminally negligent homicide?
Under Texas Penal Code § 19.05, a person commits this offense by causing a death through criminal negligence. The key is defining “criminal negligence.”
Texas Penal Code § 6.03(d) states you act with criminal negligence when you ought to be aware of a substantial and unjustifiable risk but fail to perceive it. This failure must be a gross deviation from the standard of care an ordinary person would exercise.
In plain English, this means:
- A substantial and unjustifiable risk existed.
- A reasonable person would have recognized this danger.
- The accused failed to perceive the risk.
- This failure was a gross deviation from reasonable behavior, not a simple oversight.
Criminally negligent homicide involves the inadvertent creation of risk. The person wasn’t thinking about the danger. In my years defending clients in Houston, I’ve seen how this element of “should have known” becomes the central battleground of the case.
How It Differs from Murder and Manslaughter
The Texas Penal Code has four culpable mental states: intentional, knowing, reckless, and criminally negligent. Understanding this hierarchy is essential.
- Murder (§ 19.02) is a first-degree felony (5-99 years or life) where a person intentionally or knowingly caused a death.
- Manslaughter (§ 19.04) is a second-degree felony (2-20 years) involving recklessness. The person was aware of a substantial risk of death but consciously disregarded it.
- Criminally negligent homicide (§ 19.05) is a state jail felony (180 days to 2 years). There is no intent and no conscious disregard of risk, only a failure to perceive a danger they should have seen.
| Offense | Mental State (Mens Rea) | Texas Penal Code Section | Punishment Range |
|---|---|---|---|
| Murder | Intentional/Knowing: Intentionally or knowingly causes death; or intends serious bodily injury and commits dangerous act causing death; or commits felony and dangerous act causes death. | § 19.02 | First-degree felony: 5 to 99 years or life imprisonment, up to $10,000 fine. |
| Manslaughter | Reckless: Consciously disregards a substantial and unjustifiable risk that death will occur. Aware of the risk, but proceeds anyway. | § 19.04 | Second-degree felony: 2 to 20 years imprisonment, up to $10,000 fine. |
| Criminally Negligent Homicide | Criminally Negligent: Ought to be aware of a substantial and unjustifiable risk, but fails to perceive it. Gross deviation from reasonable care. | § 19.05 | State jail felony: 180 days to 2 years in state jail, up to $10,000 fine. |
The mental state is everything. Prosecutors in Harris County may initially charge manslaughter, only for it to be reduced to criminally negligent homicide when evidence shows no conscious awareness of the risk. The case of Saunders v. State, 840 SW 2d 390 (Tex.Crim.App.1992), provides a detailed legal analysis of these distinctions.
International Perspectives: A Brief Comparison
Other legal systems grapple with similar issues. The UK’s “gross negligence manslaughter” requires a breach of a duty of care so severe it is considered criminal, as detailed by the Crown Prosecution Service. Canada’s “causing death by criminal negligence” can carry a life sentence and focuses on a “wanton or reckless disregard for the lives or safety of other persons.” These comparisons show the universal challenge of distinguishing a terrible accident from a criminal act.
Common Scenarios That Can Lead to Charges
The tragic reality of criminally negligent homicide is that it often arises from everyday situations where someone fails to recognize a deadly risk. In Houston and Harris County, a moment of inattention can quickly escalate into criminal charges.
The key question is always foreseeability: would a reasonable person have predicted that their actions—or inaction—might lead to someone’s death? This is the standard prosecutors use and the battleground where these cases are won or lost.
Vehicular Incidents
Many criminally negligent homicide charges in Houston stem from our busy roads, where the line between a tragic accident and criminal negligence can be thin.
- Driving under the influence: Even if not legally intoxicated, impairment can affect a driver’s ability to perceive risks that a sober person would see.
- Texting while driving: With the dangers of distracted driving well-known, looking at a phone instead of the road is often argued as a gross deviation from reasonable care.
- Street racing: The choice to race on public roads creates substantial and unjustifiable risks, making it difficult to argue a fatal crash was unforeseeable.
- Driving with known faulty equipment: Postponing repairs on critical parts like brakes or tires can lead to charges if those failures cause a fatal accident. Prosecutors will argue the driver should have been aware of the risk.
Public frustration over traffic fatalities, as noted in reports like “Vehicular homicide sentences not harsh enough, say victims’ families,” can lead to aggressive prosecution, making an experienced defense crucial.
Child Endangerment and Neglect
Cases involving children are among the most heartbreaking. The law expects a higher standard of care around children, and any breach can lead to criminally negligent homicide charges.
- Leaving a child in a hot car: A tragic mistake, but the law expects a reasonable person to be aware of the extreme danger of heatstroke in Houston’s climate.
- Unsafe storage of firearms: If a child accesses a loaded gun and an accident occurs, the adult who failed to secure it faces serious charges.
- Failure to provide necessary medical care: If a guardian fails to get medical help for a child with a condition a reasonable person would see as severe, charges may be filed.
- Manufacturing drugs in a home with children: This exposes children to chemicals and fire risks, which prosecutors view as a profound failure to perceive danger.
Other Negligent Acts
Beyond vehicles and child safety, charges can arise from various other situations.
- Improperly handling a loaded firearm: Waving a gun around or failing to follow basic safety rules can lead to charges if it accidentally discharges and kills someone.
- Workplace safety violations: In Houston’s industrial sectors, if a death occurs from a blatant safety hazard a supervisor should have recognized, criminal charges can follow.
- Negligent medical treatment: Though rare and typically a civil matter, criminal charges are possible in egregious cases where a medical professional’s actions are a gross deviation from the standard of care.
These situations are complex and rarely involve malicious intent. My job at The Martinez Law Firm is to challenge the prosecution’s narrative about what you “should have known” and ensure your actions are judged fairly.
Penalties and Legal Defenses in a Houston Courtroom
Facing a criminally negligent homicide charge in Houston is terrifying. The Harris County criminal justice system moves fast, and these cases carry a unique emotional burden. While there’s no alleged intent to harm, a life has been lost, and you are being held accountable. A strategic, aggressive defense is everything.
Penalties for a Conviction in Texas
A criminally negligent homicide conviction is a state jail felony with severe, life-changing consequences.
- Prison: The sentence is 180 days to two years in a state jail. Critically, you are generally not eligible for parole and must serve the full time, minus any good time credit.
- Fines: You can be fined up to $10,000.
Beyond the sentence, the collateral consequences of a felony conviction are devastating. Your future can be impacted by:
- Loss of employment and professional licenses.
- Difficulty finding housing due to background checks.
- Loss of civil rights, including the right to vote (while incarcerated), serve on a jury, or own a firearm.
- Social stigma that affects you and your family.
This is why we fight to prevent a charge from becoming a conviction that follows you forever.
Potential defenses for a criminally negligent homicide charge
The prosecution must prove every element of the charge beyond a reasonable doubt. My experience as a prosecutor taught me where these cases are vulnerable.
- Lack of Causation: We investigate whether an intervening event broke the chain of causation. For example, did a medical error, not the initial injury, cause the death? If so, your actions were not the legal cause.
- The Risk Was Not Substantial or Unjustifiable: The prosecution will portray the danger as obvious. We challenge this by showing that the risk was not as clear as it seems in hindsight. We may argue that similar actions are common and rarely result in tragedy.
- No Gross Deviation from the Standard of Care: This defense argues that what happened was a true accident, not a crime. We work to show that your actions were not a “gross deviation” from what an ordinary, prudent person might have done in the same circumstances.
- Insufficient Evidence: We scrutinize every piece of the State’s evidence—police reports, witness statements, forensics—for weaknesses, inconsistencies, and gaps. If the prosecution cannot meet its high burden of proof, we push for a dismissal or acquittal.
Every case is unique, and your defense strategy will be custom to the facts. Our commitment is to challenge the State’s narrative and protect your future.
Frequently Asked Questions about Criminally Negligent Homicide
When facing a potential homicide charge, you will have urgent questions. The legal terms are confusing, and the stakes are incredibly high. Here are straight answers to common questions we hear in our Houston office.
Is criminally negligent homicide the same as involuntary manslaughter in Texas?
No. This is a common point of confusion. Texas law does not use the term “involuntary manslaughter.” Instead, Texas has two distinct charges:
- Manslaughter requires recklessness. This means you were consciously aware of a substantial risk of death but chose to disregard it. You knew better but did it anyway.
- Criminally negligent homicide involves criminal negligence. This means you failed to perceive a risk that a reasonable person would have recognized. You should have known better but didn’t realize the danger.
This distinction is critical. Recklessness is about consciously ignoring a known risk, while negligence is about a profound failure of awareness. They require entirely different defense strategies.
Can I go to jail for a car accident that wasn’t my fault?
No. A tragic accident alone is not a crime. You cannot be convicted simply because you were the driver in a fatal accident.
The Harris County prosecutor must prove you acted with criminal negligence, a very high legal standard. They must show your actions were a gross deviation from what a reasonable person would do. Simple carelessness or a momentary lapse of attention is not enough.
If you were driving lawfully and an unforeseeable event occurred—like another driver running a red light—it is a tragedy, not a crime. However, if your conduct fell far below a reasonable standard (e.g., texting extensively, driving a car you knew was unsafe), the situation is more serious. Even then, the prosecution has a high burden of proof, and we can build a strong defense.
What is the first thing I should do if I’m investigated for criminally negligent homicide?
If law enforcement contacts you about a fatal incident, you must do two things immediately: exercise your right to remain silent and contact an experienced criminal defense attorney.
Do not speak to the police without a lawyer. It’s natural to want to explain yourself, but this is dangerous. As a former Chief Prosecutor in Harris County, I saw countless people talk their way into charges. Innocent statements can be twisted and used against you. You may think you are helping, but you could be building the prosecution’s case.
Exercising your right to remain silent is not an admission of guilt; it is smart. Once you have an attorney, we can assess the situation and protect your rights. The first hours are critical for preserving evidence and building your defense. The sooner you call, the better your chances of a favorable outcome.
Protect Your Future: Why You Need an Experienced Defense
When you’re facing charges after a tragic death, understanding the difference between an accident and criminally negligent homicide is critical. A conviction is a felony that carries jail time, fines, and a permanent criminal record that can ruin your future.
The entire case hinges on what you should have known. The prosecution will argue that any reasonable person would have seen the risk and that your actions were a “gross deviation” from common sense. Challenging this narrative requires an attorney who understands how to dismantle it.
At The Martinez Law Firm, we bring a crucial advantage to your defense: intimate knowledge of how Harris County prosecutors build their cases. As a former Chief Prosecutor for the Harris County District Attorney’s Office, Herman Martinez prosecuted these very charges. We know the playbook, we see the weaknesses in the State’s case, and we know what it takes to win in a Houston courtroom.
Too many people try to explain their way out of trouble, only to have their words used against them. Don’t make that mistake. Behind every charge is a human story, often a tragedy with no malicious intent. We are here to tell that story and fight for you.
If you are under investigation or have been charged, time is not on your side. Contact a Houston criminal defense attorney for a consultation and let us start protecting your future today.
