Can You Be Charged With Homicide After a Fatal DUI in Colorado?

A fatal DUI accident is one of the most serious situations a driver can face. When a person is accused of causing another’s death while driving under the influence, the case moves far beyond a standard DUI charge. In Colorado, prosecutors can pursue a vehicular homicide charge, which is treated as a felony and can result in lengthy prison time. Understanding how these charges work and what legal defenses are available is critical if you or someone you love is accused of causing a fatal crash.

How Colorado Defines Vehicular Homicide

Under Colorado law, vehicular homicide occurs when a person causes the death of another through reckless driving or while operating a vehicle under the influence of alcohol, drugs, or both. The law distinguishes between two forms of vehicular homicide: one based on reckless behavior and another based on intoxication.

When alcohol or drugs are involved, the prosecution does not need to prove that the driver acted recklessly. Simply showing that the driver was impaired or had a blood alcohol concentration (BAC) of 0.08 percent or higher at the time of the crash is often enough to pursue a conviction. This makes DUI-related fatalities especially serious, as even a momentary lapse in judgment can lead to devastating consequences.

Vehicular Homicide vs. Manslaughter or Murder Charges

Although vehicular homicide is the most common charge after a fatal DUI, there are situations where prosecutors may attempt to elevate the case to a higher offense, such as manslaughter or even second-degree murder. This typically happens when the state believes the driver’s conduct showed “extreme indifference to human life.” For example, driving at excessive speeds through a crowded area while intoxicated could lead to more serious allegations.

Vehicular homicide due to intoxication is a class 3 felony in Colorado, carrying penalties that may include 4 to 12 years in prison and fines up to $750,000. However, second-degree murder or manslaughter charges can carry even harsher penalties. The key difference lies in intent and the level of recklessness involved, which is why a strong defense strategy is essential.

Evidence Used in Fatal DUI Cases

In a fatal DUI case, prosecutors rely on a variety of evidence to prove guilt. This evidence often includes:

  • Blood alcohol concentration (BAC) test results
  • Field sobriety test performance
  • Police observations and dashcam footage
  • Accident reconstruction reports
  • Witness statements and expert testimony
  • Surveillance video or black box data from vehicles

While this evidence may seem convincing, many aspects of DUI testing and accident reconstruction are open to challenge. A defense attorney can question whether testing procedures were followed correctly, whether equipment was properly maintained, and whether other factors, such as road conditions or another driver’s actions, played a role in the crash.

Building a Strong Defense After a Fatal DUI

Defending against vehicular homicide charges requires careful analysis of every detail. Even if a driver’s BAC was above the legal limit, the prosecution must still prove that intoxication directly caused the accident. In some cases, a mechanical failure, poor weather, or the actions of another driver may have been the actual cause of the collision. Establishing these facts can significantly impact the outcome of the case.

Other common defense strategies include challenging the accuracy of blood or breath tests, questioning the legality of the traffic stop, and disputing the reliability of eyewitness accounts. A skilled attorney can also present mitigating evidence to reduce the severity of the charges or negotiate for lesser penalties.
