Aspen Vehicular Assault and Homicide Defense Lawyer

A serious accident on Highway 82 or a mountain road outside Aspen can shift from a traffic tragedy to a felony prosecution with very little warning. Aspen vehicular assault and homicide defense sits at the intersection of serious criminal law, accident reconstruction science, and Colorado’s aggressive charging practices, and the difference between a misdemeanor disposition and a decade in prison often comes down to decisions made in the first weeks after an arrest. Reid DeChant defends people facing these charges across Colorado, including Pitkin County and the communities along the Roaring Fork Valley corridor.

What Colorado Actually Charges in These Cases

Colorado law draws a sharp line between an accident, however tragic, and criminal conduct. Prosecutors build vehicular assault and vehicular homicide cases on two possible theories: driving under the influence, or driving with a reckless disregard for the safety of others. The DUI-based theory carries heavier mandatory penalties and is far more commonly filed, because the existence of a blood draw can make the case feel open-and-shut to a district attorney’s office. The recklessness-based theory requires proving more, but it still carries serious felony exposure.

Vehicular assault under the DUI theory is a class 4 felony. Vehicular homicide under the DUI theory is a class 3 felony. Those class numbers correspond to sentencing ranges that include mandatory prison time under Colorado law, not simply probation or fines. Pitkin County has its own particular enforcement culture, shaped by the volume of mountain driving, seasonal tourist traffic, and a court system that takes fatal crashes on those roads seriously. The Eagle County border sits close by, and cases involving Highway 82 or I-70 near Glenwood Canyon can draw intense prosecutorial attention from multiple jurisdictions.

One charge frequently filed alongside or instead of vehicular homicide is criminally negligent homicide, a class 5 felony. The charging decision often depends on the prosecutor’s read of your conduct, but that read can be challenged. How the initial crash report is written, whether witnesses were interviewed carefully, and what the toxicology timeline actually shows all affect which charge sticks and which does not.

The Evidence That Drives These Prosecutions, and Where It Breaks Down

Blood tests are central to most DUI-based vehicular assault and homicide cases. Law enforcement in Pitkin County and surrounding areas typically draws blood, not breath, in serious crash investigations. Blood draws introduce a chain of custody that has to be followed precisely. The sample has to be taken within a certain window after the driving occurred, stored correctly, tested using validated methods, and handled by personnel who can be cross-examined. Any gap in that chain creates grounds to challenge the result. Reid has studied impaired driving defense in depth and understands how to interrogate toxicology reports beyond just reading the number on the page.

Accident reconstruction is the other major evidentiary battleground. Law enforcement agencies will deploy their own reconstructionists in fatal or serious injury crashes. These experts generate opinions about speed, point of impact, driver input, and causation. Those opinions are not always correct, and they are built on physical evidence that should be examined independently as quickly as possible, because the scene changes. Skid marks fade. Road conditions shift. Debris gets cleared. Getting an independent reconstruction done early is not optional in serious cases, it is essential.

A third area that often goes unexamined is the conduct of the investigation itself. Was the express consent advisement given correctly? Were you read Miranda warnings at the appropriate time? Did law enforcement obtain a warrant before drawing blood, or did they rely on a consent or exigency theory that can be challenged? The procedural protections in these cases matter enormously, and violations do lead to suppression of evidence.

Aspen and Pitkin County: How Location Shapes These Cases

Aspen draws a substantial amount of the criminal court activity in Pitkin County, and the Pitkin County District Court handles felony vehicular cases with a level of scrutiny that reflects both the severity of mountain driving accidents and the high-profile nature of the community. Highway 82 through the Roaring Fork Valley is one of the more heavily patrolled corridors in western Colorado, and serious accidents involving injury or death on that stretch receive thorough law enforcement investigation, including reconstruction and toxicology review as a matter of course.

If the incident involved a vehicle traveling on Interstate 70 through Glenwood Canyon, the case may land in Garfield County rather than Pitkin, which means a different courthouse, a different district attorney’s office, and different prosecutorial tendencies. Understanding which jurisdiction will handle the case, and who in that office typically handles serious vehicular felonies, is part of the groundwork a defense attorney has to do from the start.

The tourist and seasonal worker population in the Aspen area also creates cases involving out-of-state drivers, commercial drivers, and people who hold professional licenses. For those individuals, a conviction carries consequences well beyond Colorado’s criminal penalties: a CDL can be disqualified, a pilot’s certificate can be revoked, and a medical license can face board action. Reid has worked with clients holding professional licenses who needed defense counsel who understood those downstream consequences, not just the courtroom result.

Questions People Facing These Charges Actually Ask

Can vehicular homicide charges be filed even if the other driver was at fault?

Yes, and this comes up more than people expect. Colorado prosecutors look at every factor contributing to the crash, but their charging decision focuses on your conduct. If they believe you were impaired or reckless regardless of what the other party did, charges can follow. How fault is allocated in a civil sense does not control criminal charging decisions.

Does a blood test result automatically mean a conviction?

No. A blood test result is evidence, not a verdict. The result can be challenged on procedural grounds, the testing methodology can be questioned, and the timeline between driving and the draw can affect how much weight the result deserves. There are many cases where the reported BAC does not accurately reflect what a driver’s blood alcohol was at the moment of driving.

What is the difference between vehicular homicide and criminally negligent homicide?

Vehicular homicide requires proof that the driver operated a vehicle while DUI or with reckless disregard for others, and that this caused a death. Criminally negligent homicide requires proof of criminal negligence, which is a lower mental state than recklessness. Prosecutors sometimes file the negligence charge when they cannot prove recklessness beyond a reasonable doubt, but it still carries felony exposure.

Will I automatically lose my driver’s license if charged with vehicular assault or homicide?

License consequences are separate from the criminal case and are handled through the DMV’s express consent process. There are strict deadlines to request a hearing, and missing that window typically means an automatic revocation. Reid has handled numerous DMV express consent hearings and has had many of those actions dismissed.

What happens if someone was seriously injured but not killed?

Vehicular assault is the charge when a victim survives with serious bodily injury. It carries its own felony classification and sentencing range, and it is prosecuted with the same intensity as homicide cases in serious injury crashes. The evidentiary issues are similar: toxicology, reconstruction, and the investigation’s procedural compliance all matter.

Can these charges be reduced or dismissed?

Yes. Results vary, and past outcomes do not predict future ones, but DeChant Law has obtained case dismissals and not-guilty verdicts in serious criminal cases. In vehicular cases, the strength of the toxicology challenge, the quality of an independent reconstruction, and the procedural compliance of the investigation all create potential paths to a better outcome. Nothing is guaranteed, but the defense built matters.

How soon do I need to contact a defense attorney after a crash like this?

As soon as possible. The physical evidence at the crash scene starts degrading immediately. The DMV clock on a hearing request starts running from the time of the arrest or citation. Witness memories shift. The sooner the defense begins gathering and preserving evidence, the better positioned you are.
