Phoenix Driver Sentenced to 8 Years After Fatal DUI Crash on I-10

Recently, the Arizona Department of Public Safety (AZDPS) announced that a Phoenix man was sentenced to eight years in prison after a fatal crash that occurred on Interstate 10 in 2024. Continue reading to learn more about this recent development, how manslaughter and DUI charges typically work in Arizona, and the importance of hiring a seasoned Tempe criminal defense lawyer who can defend your rights and future if you’re currently facing such charges. Here are some of the questions you may have:

What Happened in the Interstate 10 Crash?

According to the Arizona Department of Public Safety, investigators determined that a driver, Ukel Mario Celbirio, was traveling westbound on Interstate 10 when he left the travel lanes and entered the shoulder, where a disabled Mercedes-Benz had been parked. At the time of the collision, two individuals were outside of the disabled vehicle attempting to secure a damaged sunroof.

As a result of the crash:

• One 24-year-old victim suffered fatal injuries.
• A second victim sustained injuries that were not considered life-threatening.

Following an extensive investigation, authorities reported that investigators reviewed numerous forms of evidence before reaching their conclusions. According to AZDPS, that investigation included:

• Witness interviews
• Crash scene evidence
• Vehicle examinations
• Body-worn camera footage
• Crash data retrieval
• Laboratory testing

Investigators ultimately concluded that the driver was impaired by alcohol at the time of the collision. In March 2026, Ukel Mario Celbirio was sentenced to eight years in the Arizona Department of Corrections following a manslaughter conviction.

When Can a Fatal Crash Lead to Manslaughter Charges in Arizona?

One of the biggest misconceptions people have is that every fatal car accident automatically results in criminal charges. Fortunately, that is not how the legal system works. Instead, prosecutors must prove every element of the offense beyond a reasonable doubt before they can obtain a conviction.

Generally speaking, Arizona prosecutors may pursue manslaughter charges when they believe a person recklessly caused another individual’s death. If alcohol or drugs are believed to have played a role in the collision, investigators will often spend months gathering evidence before determining which criminal charges, if any, are appropriate. Some of the most common types of evidence that are reviewed during these investigations are as follows:

• Blood or breath alcohol testing
• Field sobriety evidence
• Crash reconstruction reports
• Witness statements
• Surveillance or body camera footage
• Electronic crash data from the vehicles involved

What Are the Penalties for Manslaughter in Arizona?

Manslaughter is a Class 2 felony under Arizona law. Because of this, a conviction can carry significant and long-lasting consequences. Depending on the circumstances of the case, those penalties may include the following:

• Years of incarceration
• Hefty fines, as well as associated court costs
• Probation, in some instances
• A permanent felony conviction, in some cases
• The loss of certain civil rights

How Is DUI Different From Vehicular Manslaughter?

Although these offenses are frequently connected, they are not the same thing. For example:

• A DUI case focuses primarily on whether a person unlawfully operated a motor vehicle while impaired or while having an unlawful blood alcohol concentration.
• A manslaughter case focuses on whether prosecutors can prove that the defendant recklessly caused another person’s death.

What Rights Do You Have if You Are Accused?

Being accused of a serious felony offense can be overwhelming, especially when the allegations involve a fatal accident. Fortunately, everyone charged with a crime has important constitutional rights, regardless of the allegations against them. Those rights are as follows:

• The right to remain silent.
• The right to be represented by an attorney.
• The right to challenge the prosecution’s evidence.
• The right to cross-examine witnesses.
• The right to a fair trial.
• The right to require the prosecution to prove guilt beyond a reasonable doubt.

The bottom line is that allegations involving DUI and manslaughter should never be taken lightly. If you are under investigation or have already been charged with manslaughter, vehicular homicide, DUI, or any other related offense, it is of paramount importance that you retain the services of a knowledgeable and skilled Phoenix criminal defense lawyer who can effectively advocate for your rights, every step of the way.
