Intoxication Manslaughter

What Is Intoxication Manslaughter in Texas?

Intoxication manslaughter represents one of the most serious charges in Texas criminal law. This offense occurs when someone causes the death of another person by accident or mistake while operating a motor vehicle, aircraft, watercraft, or amusement ride while intoxicated. Unlike murder charges, intoxication manslaughter doesn’t require proof that you intended to kill someone—the prosecution only needs to demonstrate that your intoxicated state led to someone’s death.

The charge applies whether you were under the influence of alcohol, drugs (including prescription medications), or any combination of substances that impaired your normal mental or physical faculties. Texas law defines “intoxicated” as having a blood alcohol concentration of 0.08 or higher, or lacking normal use of mental or physical faculties due to substance use.

Even if your BAC was below the legal limit, you can still face intoxication manslaughter charges if the prosecution can prove that drugs or alcohol impaired your ability to drive safely.

Real-World Impact

These charges often arise from tragic accidents where drivers had no intention of harming anyone. Even if your BAC was below the legal limit, you can still face charges if prosecutors can demonstrate that alcohol or drugs impaired your driving ability.

At McConathy Law, our experience includes defending clients facing intoxication manslaughter charges in complex situations involving questions of causation and intoxication levels.

Texas Penal Code § 49.08: Legal Definition & Elements

Texas Penal Code § 49.08 specifically outlines intoxication manslaughter as a second-degree felony. To secure a conviction, prosecutors must prove four key elements beyond a reasonable doubt:

1. Causation: You operated a motor vehicle, aircraft, watercraft, or amusement ride

2. Intoxication: You were intoxicated at the time of operation

3. Death: Your actions caused the death of another person

4. Accidental Nature: The death occurred by accident or mistake

The prosecution doesn’t need to prove you intended to cause harm—only that your intoxicated operation of a vehicle led to someone’s death. This lower standard of proof makes these cases particularly challenging to defend without experienced legal representation.

Legal Standards in Texas Courts

Texas courts apply strict standards when evaluating intoxication manslaughter cases:

• Causation Analysis: Courts examine whether your intoxication was a “but-for” cause of the death
  
  
• BAC Evidence: Blood alcohol tests conducted within three hours of driving create legal presumptions
  
  
• Timing Requirements: Prosecutors must prove intoxication at the time of driving, not just at the time of testing
  
  
• Accident vs. Intent: The accidental nature distinguishes this charge from murder or criminally negligent homicide

Penalties for Intoxication Manslaughter in Texas

Intoxication manslaughter is classified as a second-degree felony in Texas, carrying severe consequences that extend far beyond prison time:

Enhanced Penalties and Aggravating Factors

Several factors can increase the severity of your punishment, with significant enhancements added by the Texas Legislature in 2025:

New 2025 First-Degree Enhancements: Under recent legislative changes, intoxication manslaughter becomes a first-degree felony (5-99 years or life in prison) if you caused the death of more than one person during the same criminal transaction, or if you have a prior intoxication-related offense and were in violation of certain immigration-related offenses at the time.

Previous Convictions: Prior DWI convictions or felony records can elevate the offense to a first-degree felony, punishable by 5-99 years in prison.

High BAC Levels: Blood alcohol concentrations significantly above 0.08 may result in harsher sentencing recommendations.

Child Passenger: If a child under 15 was in your vehicle during the incident, you could face additional charges under Texas Penal Code § 49.045.

Commercial Vehicle Operation: Enhanced penalties apply if you were operating a commercial vehicle with a CDL.

The financial impact extends beyond criminal fines. Civil lawsuits from victim families can result in millions of dollars in damages, including wrongful death claims, lost earning capacity, and punitive damages. Our legal team works closely with clients to address both criminal charges and potential civil liability.

Common Scenarios Leading to Charges

Understanding how intoxication manslaughter charges typically arise can help illustrate the serious nature of these cases. Most charges stem from seemingly routine situations that spiral into tragedy:

Vehicle Collisions

The majority of cases involve car accidents where impaired driving contributes to fatal crashes. These often occur at intersections, during lane changes, or when drivers fail to maintain proper following distances.

Pedestrian Accidents

Intoxicated drivers frequently strike pedestrians who are crossing streets legally. Alcohol impairs depth perception and reaction time, making it difficult to spot and avoid pedestrians, especially in low-light conditions.

Single-Vehicle Crashes with Passengers

When an intoxicated driver crashes their own vehicle, killing a passenger, they can face intoxication manslaughter charges even though the passenger chose to ride with them.

Watercraft and Aircraft Operations

Texas law extends beyond motor vehicles to include boats, jet skis, and aircraft. We’ve successfully defended clients facing charges related to boating accidents on Texas lakes and waterways where mechanical failure, not intoxication, was determined to be the cause.

How Is Intoxication Manslaughter Different from Intoxication Assault?

Many clients confuse these related but distinct charges. The primary difference lies in the outcome—intoxication assault involves serious bodily injury, while intoxication manslaughter involves death.

Intoxication Assault (Texas Penal Code § 49.07):

• Third-degree felony
• 2-10 years in prison
• Victim suffers serious bodily injury
• Fine up to $10,000

Intoxication Manslaughter (Texas Penal Code § 49.08):

• Second-degree felony
• 2-20 years in prison
• Victim dies from injuries
• Fine up to $10,000

Both charges require the same level of proof regarding intoxication and causation. However, the more severe consequences of intoxication manslaughter demand more aggressive defense strategies and immediate legal intervention.

Prosecutors sometimes file intoxication assault charges initially, then upgrade to manslaughter if the victim dies from their injuries. This progression underscores the importance of having experienced legal representation from the moment charges are filed.

Defense Strategies for Intoxication Manslaughter Charges

Successful defense of intoxication manslaughter charges requires a multi-faceted approach that challenges every aspect of the prosecution’s case. Our legal team employs several proven strategies depending on your case’s specific circumstances.

Challenging Intoxication Evidence

The prosecution must prove you were intoxicated at the time of the incident. We attack this element through multiple avenues:

Blood Test Challenges:
We examine the entire process, from the initial blood draw to laboratory analysis. Issues we commonly identify include improper collection procedures, contaminated samples, broken chain of custody, and laboratory errors.

Rising Blood Alcohol Defense:
Your BAC may have been below the legal limit while driving but rose to illegal levels by the time blood was drawn. This defense requires expert testimony about alcohol absorption rates and metabolism.

Medical Condition Defenses:
Certain medical conditions can produce false positive results or create symptoms that mimic intoxication.

Even if intoxication is proven, we work to demonstrate that your intoxication didn’t cause the death:

Alternative Causation:
Other factors may have contributed to or caused the fatal accident, such as poor road conditions, mechanical failures, or the victim’s own actions.

Intervening Causes:
Events that occurred after your actions but before the death may have broken the causal chain.

Accident Reconstruction:
Expert analysis can show that the accident would have occurred regardless of your level of intoxication.

Procedural Defenses

Law enforcement must follow specific procedures when investigating these cases. Violations of your constitutional rights can result in evidence being excluded:

Unlawful Traffic Stop:
If police lacked reasonable suspicion to stop your vehicle initially, all subsequent evidence may be inadmissible.

Miranda Rights Violations:
Statements made during custodial interrogation without proper warnings cannot be used against you.

Search and Seizure Issues:
Evidence obtained through illegal searches must be suppressed.

Life After an Intoxication Manslaughter Conviction

The consequences of an intoxication manslaughter conviction extend far beyond your prison sentence. Understanding these long-term impacts underscores the importance of fighting these charges with experienced legal representation.

Employment Consequences

A felony conviction creates permanent barriers to employment opportunities. Many employers conduct background checks and automatically disqualify applicants with felony records, particularly for positions involving driving, public trust, or professional licensing.

Professional Licensing Issues

Professional licenses in healthcare, law, education, and finance may be suspended or revoked following a felony conviction, potentially ending careers that took years to build.

Civil Liability

Criminal conviction often serves as evidence in wrongful death lawsuits filed by victim families. These civil cases can result in financial judgments worth millions of dollars, creating lifelong financial obligations.

Personal Relationships

The stigma associated with causing someone’s death while intoxicated can damage personal relationships and create lasting psychological trauma for both you and your family members.

Frequently Asked Questions

What is the punishment for intoxication manslaughter in Texas?

Intoxication manslaughter is a second-degree felony in Texas, punishable by 2-20 years in prison and fines up to $10,000. Enhanced penalties can increase the sentence to 5-99 years if you have prior felony convictions or other aggravating factors apply. Additional consequences include driver’s license suspension, probation requirements, and potential civil liability.

Is intoxication manslaughter considered a felony?

Yes, intoxication manslaughter is classified as a second-degree felony under Texas Penal Code § 49.08. This classification makes it more serious than most DWI charges but less severe than first-degree felonies like murder. A felony conviction creates permanent consequences including loss of voting rights, inability to own firearms, and barriers to employment and housing.

Can charges be reduced from intoxication manslaughter to something lesser?

Experienced defense attorneys can often negotiate charge reductions depending on the evidence and circumstances. Possible reduced charges include intoxication assault (if the death wasn’t directly caused by your actions), criminally negligent homicide, or standard DWI charges. Success depends on challenging the prosecution’s evidence regarding causation, intoxication level, and the circumstances surrounding the incident.

What’s the difference between intoxication assault and manslaughter?

The primary difference is the outcome for the victim. Intoxication assault involves serious bodily injury, while intoxication manslaughter involves death. Intoxication assault is a third-degree felony (2-10 years in prison), while intoxication manslaughter is a second-degree felony (2-20 years in prison). Both charges require proof of intoxication and causation, but manslaughter carries more severe penalties due to the fatal outcome.

Can you go to prison for your first DWI if it caused a death in Texas?

Yes, intoxication manslaughter charges apply regardless of whether you have prior DWI convictions. Even first-time offenders face 2-20 years in prison if convicted of causing someone’s death while intoxicated. This is why immediate legal representation is crucial—the stakes are dramatically higher than standard DWI charges, and you need attorneys experienced in defending serious felony cases.
