Missouri Felony DUI Accident With Injury Attorney

A felony DUI involving an accident with injury is one of the most serious DUI charges under Missouri law. These cases carry prison exposure, long-term license consequences, and life-altering outcomes if not handled correctly from the very beginning.

Many people are surprised to learn that prior DUI or DWI convictions are not required for a DUI to be charged as a felony when an accident involves physical injury. In these cases, the felony classification is based on the injury allegation itself, not a driver’s history.

Although people commonly search for a DUI attorney, Missouri legally charges these cases as Driving While Intoxicated (DWI). DUI and DWI are often used interchangeably by the public. This page addresses felony DUI accident charges under Missouri DWI law.

Kissell Law Group has extensive experience defending serious felony DUI accident cases statewide, where timing, forensic evidence, and causation determine whether the charge stands or falls.

When a DUI Becomes a Felony Due to Injury

Under Missouri law, a DUI can be charged as a felony based solely on an alleged physical injury, regardless of whether the driver has any prior offenses, pursuant to RSMo §§ 577.010, 577.001, and 577.023.

In these cases:

  • Prior offenses do not control felony status
  • The State’s burden of proof is significantly higher
  • Prosecutors must prove additional elements beyond intoxication

Felony DUI accident cases are not simply “DUI plus injury.” They are legally and factually different cases.

The State Must Prove Additional Elements

To convict someone of a felony DUI based on an injury accident, the State must prove all elements of a DUI, plus additional elements related to the accident itself.

Specifically, the State must establish beyond a reasonable doubt:

  1. Operation of a motor vehicle
  2. Intoxication at the time of operation under RSMo § 577.010
  3. Criminal negligence
  4. That the criminal negligence caused physical injury

Failure to prove any one of these elements means the felony charge cannot stand.

Criminal Negligence Is Not Automatic

Criminal negligence is a separate legal element and is not presumed simply because alcohol is involved.

Under Missouri law, criminal negligence requires proof that:

  • The driver failed to be aware of a substantial and unjustifiable risk
  • The failure was a gross deviationfrom the standard of care
  • The conduct directly caused the alleged physical injury

Accidents happen for many reasons unrelated to intoxication, including road conditions, vehicle defects, weather, medical events, or the actions of other drivers.

Intoxication alone does not establish criminal negligence.

Timing Is Often the Strongest Defense in Injury DUI Cases

In felony DUI accident cases, timing is frequently the States weakest link.

The prosecution must prove:

  • When the accident occurred
  • When the defendant last operated the vehicle
  • When intoxication existed relative to operation

These cases often involve:

  • No eyewitnesses to the accident
  • Delayed police arrival
  • Emergency medical treatment before testing
  • Blood draws conducted hours after the alleged driving

As we have previously addressed in Missouri’s no-refusal DUI enforcement practices, probable cause and timing must exist before an arrest, not reconstructed later. Officers cannot arrest first and determine timing afterward.

If the State cannot reliably establish intoxication at the time of operation, it cannot meet its burden under RSMo § 577.010.

Unknown Accident Timing Creates Reasonable Doubt

Many felony DUI accident cases involve unanswered questions:

  • How long before officers arrived did the accident occur
  • Whether anyone observed the vehicle being driven
  • Whether alcohol was consumed after the accident
  • Whether medical conditions affected behavior

If the timing of operation is unclear or speculative, reasonable doubt exists. These gaps often form the foundation of a strong defense.

Forensic Accident Reconstruction Experience Matters

Felony DUI accident cases often rise or fall on how the crash itself is interpreted, not simply on what a report claims.

Attorney Thomas Kissell has personally deposed Missouri State Highway Patrol forensic accident reconstructionists, including senior investigators responsible for complex crash analyses. Through that work, he developed his own analytical charts and methodologies based on electronic data, physics, roadway evidence, and vehicle damage, not assumptions.

We do not accept accident conclusions at face value. We test them.

What We Analyze Beyond the Crash Report

Our forensic review commonly includes:

  • Electronic Data Recorder (EDR)information
  • Vehicle speed, braking, throttle, and steering input
  • Event timing relative to airbag deployment
  • Physical roadway evidence such as yaw marks, gouge marks, and debris fields
  • Damage patterns and crush analysis from photographs
  • Consistency between physical evidence and investigative conclusions

EDRs are often casually referred to as “black boxes,” but that term comes from aviation. In vehicle cases, EDR data is limited, specific, and context-dependent. Without proper interpretation, it can be misleading or flatly incorrect.

Crash Report vs Physical Evidence Why Assumptions Fail in Felony DUI Accident Cases

Crash Report Conclusions

Physical Evidence Analysis

Narrative summaries and interviews

Objective electronic and physical data

Estimated speeds

Actual speed and braking data from EDR

Officer assumptions about fault

Physics-based reconstruction

General impact descriptions

Measured crush damage and energy transfer

Time inferred after the fact

Event sequencing from data and scene evidence

Alcohol assumed as cause

Alternative causes evaluated and tested

Conclusions accepted as written

Conclusions challenged and verified

 

In serious injury cases, the truth is often found in the data, not the assumptions.

Criminal and License Exposure in Felony DUI Injury Cases

A felony DUI involving injury can result in:

  • Prison exposurein the Missouri Department of Corrections
  • Long-term or permanent license revocation under RSMo §§ 060 and 302.525
  • Mandatory ignition interlock requirements under RSMo § 302.309

The stakes are high, but outcomes depend on proof, not labels.

These Cases Require Immediate, Experienced Defense

Felony DUI accident cases move quickly. Evidence disappears, timelines harden, and assumptions turn into charges.

Effective defense often requires:

  • Immediate investigation of accident timing
  • Forensic review of crash data and vehicle systems
  • Analysis of medical and toxicology records
  • Challenging probable cause and arrest sequencing
  • Litigating constitutional and evidentiary issues

These cases are not routine and should never be treated as such.

Our Approach to Felony DUI Accident Defense

Every felony DUI accident case begins with a free consultation. Our team gathers detailed information immediately so the matter can be evaluated accurately. These cases are reviewed internally, including attorney review, before representation is offered.

Clients can expect:

  • Clear explanation of felony exposure and prison risk
  • Honest assessment of evidentiary strengths and weaknesses
  • A defense strategy focused on timing, causation, and forensic proof
  • Immediate action once representation begins

We are selective in the felony cases we accept and take seriously the responsibility of defending clients facing life-altering charges.
