Louisville Vehicular Assault/Homicide Defense Lawyer

A crash that results in serious injury or death transforms a traffic matter into a felony prosecution almost instantly. Investigators arrive. Blood is drawn. Witnesses are interviewed. Charges follow. For someone facing Louisville vehicular assault or homicide charges, the gap between what actually happened and what the evidence appears to show can feel impossible to explain without someone who knows how to read accident reconstruction reports, challenge toxicology results, and present a complete picture to a jury. Reid DeChant has handled serious felony cases at the trial level and understands what it takes to defend charges where the stakes include years in prison and a permanent felony record.

What Colorado Charges Actually Mean in These Cases

Colorado draws a legal line between two distinct charges when a driver causes death or serious injury: vehicular assault and vehicular homicide. The difference matters enormously in terms of sentencing exposure, and prosecutors have discretion in how they charge depending on what evidence they have.

Vehicular assault applies when a driver causes serious bodily injury to another person. Under Colorado law, if the driver was DUI at the time, the charge becomes a class 4 felony. Without the DUI element, reckless driving causing serious injury is a class 5 felony. Both carry potential prison sentences and years of mandatory parole supervision afterward.

Vehicular homicide, as its name suggests, involves a death. A DUI-related vehicular homicide is a class 3 felony in Colorado, carrying a sentencing range of four to twelve years in the Department of Corrections, though aggravating factors can push that higher. A reckless vehicular homicide, without proof of impairment, is a class 4 felony. These are not charges that resolve quietly. They are prosecuted aggressively, often with significant media attention and community pressure on the DA’s office.

Louisville sits in Boulder County, and cases originating in the area move through Boulder District Court. The roads most commonly involved in serious crash investigations in and around Louisville include US-36, McCaslin Boulevard, and the intersections along South Boulder Road. These are high-speed corridors where collisions can turn catastrophic, and law enforcement has well-worn protocols for how they respond and document the scene.

How the Investigation Shapes the Case Against You

By the time charges are filed, investigators have already built a version of events. That version does not always match reality, but it is the version in the file when the DA sits down to write the complaint. Understanding what went into that investigation, and where it may have cut corners or drawn unfair inferences, is where a defense starts.

Accident reconstruction is central to most vehicular assault and homicide cases. Law enforcement often deploys a specialized team that photographs the scene, measures skid marks, documents road and weather conditions, and may use software to model vehicle speeds and trajectories. These reconstructions are presented as science, but they involve assumptions. Input variables can be challenged. The reconstruction expert can be cross-examined. Competing experts can be retained.

Toxicology results are a second major battleground. If the state is claiming impairment, the blood draw is the heart of their evidence. But blood draws must be conducted within specific timeframes. Chain of custody must be documented. The lab handling the sample must follow proper procedures. There is a reason Colorado’s express consent laws have generated significant litigation. Procedural failures in how a blood test is administered or processed have led to suppression of results in cases across the state, including DUI cases handled by DeChant Law where DMV express consent actions were dismissed on exactly these grounds.

Witness statements collected in the immediate aftermath of a crash can be inconsistent, influenced by shock, and sometimes contradicted by physical evidence. Cell phone records, surveillance footage from nearby businesses, and data pulled from a vehicle’s event data recorder add layers to what investigators claim happened. A defense that treats these as fixed facts rather than things to be interrogated will not serve the client well.

Where These Cases Break Down for the Prosecution

Vehicular homicide and assault cases are not as airtight as they might appear on first read. Several factors can significantly affect how the case resolves.

Causation is one. Even if the driver was impaired, the state must prove that the impairment actually caused the collision and the resulting injury or death. If the other driver ran a red light, if road conditions were the primary factor, or if a mechanical failure contributed to the crash, causation becomes genuinely contested. The state cannot simply point to a BAC above the legal limit and rest.

Recklessness, as a legal standard, is also worth examining carefully. For the non-DUI version of these charges, the prosecution must show the driver acted with conscious disregard of a substantial and unjustifiable risk. Ordinary negligence does not meet that bar. In cases where the driver’s conduct was careless or inattentive but not egregious, the difference between a felony conviction and a different resolution can hinge on how that distinction is argued.

Plea negotiations happen in these cases, but they require leverage. Leverage comes from exposing weaknesses in the state’s evidence, filing targeted motions, and making clear that the defense is prepared to go to trial. Reid DeChant has tried cases to verdict, including DUI cases, felony assault cases, and domestic violence charges in multiple Colorado counties. That experience matters when prosecutors are deciding how to respond to defense arguments.

Questions People in Louisville Ask About These Charges

Can I be charged with vehicular homicide even if I wasn’t drunk?

Yes. Colorado law allows vehicular homicide charges based on reckless driving without any allegation of impairment. However, the reckless standard requires more than simply causing an accident. The driver’s conduct must show a conscious disregard of a substantial and unjustifiable risk. What that means in a specific case depends heavily on the facts, which is why the details of how the crash happened matter so much to how charges are framed.

What happens if the accident was partly my fault and partly the other driver’s fault?

Comparative fault does not work the same way in criminal law as it does in civil cases. But shared causation can still be relevant. If the other party’s actions contributed substantially to causing the collision, that can undercut the prosecution’s causation argument or be used to challenge the degree of recklessness attributed to the defendant. This is something a defense attorney works through with accident reconstruction evidence and witness accounts.

Will my driver’s license be suspended even before my criminal case is resolved?

If the vehicular charges are tied to a DUI allegation, yes. Colorado’s express consent law triggers a separate DMV proceeding that operates independently of the criminal case. A hearing request must be filed quickly, and failure to request one results in automatic license revocation. DeChant Law handles both the criminal defense and the DMV hearing side of these cases.

How long does a vehicular homicide case typically take in Boulder County?

Serious felony cases in Boulder County District Court routinely take a year or more from filing to resolution, sometimes longer if expert witnesses are involved and pretrial motions are litigated. Cases that go to trial take additional time. The timeline is not a reason to wait before engaging a defense attorney. Early investigation, witness contact, and evidence preservation matter.

Is prison mandatory for a vehicular homicide conviction in Colorado?

Colorado law classifies DUI-based vehicular homicide as a class 3 felony, and that carries presumptive prison time. However, sentencing outcomes depend on the specific facts, criminal history, and what the defense presents at sentencing. Not every case results in the maximum, and some cases resolve short of trial on charges that carry different sentencing ranges. The specific outcome depends entirely on what the evidence shows and how the case is handled throughout.

Can evidence from the accident scene be challenged?

Yes. Accident reconstruction is not infallible. The methods, assumptions, and qualifications of the state’s experts can all be challenged. Physical evidence collected improperly or without proper documentation can be subject to suppression. Surveillance footage and event data recorder information must be authenticated. Experienced criminal defense attorneys scrutinize every layer of the state’s evidence, not just the most visible elements.

What should I do immediately after a crash that resulted in someone’s injury or death?

Colorado law requires drivers to stop, render aid, and identify themselves. Beyond those legal obligations, the most important thing is to avoid making statements to law enforcement beyond what is legally required. Investigators are building a case from the first moments on scene. Speaking with a defense attorney before making detailed statements protects your ability to respond strategically to whatever charges follow.
