Strong Legal Representation for Gross Vehicular Manslaughter charges in California

A charge under Penal Code 191.5(a) PC is one of the most serious DUI-related felonies in California. It carries up to 10 years in state prison and when a defendant has a prior DUI conviction prosecutors will often attempt to elevate the case to second-degree murder under the Watson doctrine which carries 15 years to life. These cases move quickly and the evidence begins to deteriorate from the moment of the collision. If you or someone you know has been charged in Los Angeles contact our office immediately. At The Law Offices of Arash Hashemi our criminal defense attorney has spent over 20 years defending clients against gross vehicular manslaughter and DUI-related homicide charges throughout Los Angeles County.

What Is Gross Vehicular Manslaughter While Intoxicated?

Penal Code 191.5(a) defines gross vehicular manslaughter while intoxicated as the unlawful killing of a human being without malice aforethought while driving a vehicle under the influence of alcohol or drugs and through the commission of an unlawful act not amounting to a felony or through gross negligence. Three elements must all be present: the driver was legally intoxicated, someone died as a result of the collision, and the driving involved gross negligence or an unlawful act.

Gross negligence is more than ordinary carelessness. It means the driver’s conduct created a high risk of death or great bodily injury that a reasonable person would have recognized as dangerous. Speeding at extreme speeds, running red lights at busy intersections, driving on the wrong side of the highway, and similar conduct typically satisfies the gross negligence standard. The prosecution does not need to prove the defendant intended to kill anyone — only that the conduct was reckless enough to meet the gross negligence threshold while the driver was intoxicated.

PC 191.5(a) vs PC 191.5(b) — What Is the Difference?

PC 191.5(a) — Gross Vehicular Manslaughter While Intoxicated: Requires proof of gross negligence in addition to intoxication. Always a felony. Carries 4, 6, or 10 years in state prison. This is the more serious subsection and the one most frequently charged when the driving conduct was particularly dangerous.

PC 191.5(b) — Vehicular Manslaughter While Intoxicated Without Gross Negligence: Applies when the driver was intoxicated and caused a death but the driving conduct involved only ordinary negligence rather than gross negligence. A wobbler that can be charged as a misdemeanor carrying up to one year in county jail or a felony carrying 16 months, 2 years, or 3 years in state prison. Securing treatment of the case under 191.5(b) rather than 191.5(a) is frequently one of the primary defense objectives because the difference in sentencing exposure between the two subsections can be seven or more years in state prison.

DUI Causing Death and Watson Murder — When the Charge Becomes Second-Degree Murder

When a defendant charged under PC 191.5(a) has a prior DUI conviction on their record prosecutors in Los Angeles regularly attempt to elevate the charge to second-degree murder under the Watson murder doctrine. The Watson doctrine holds that a defendant who was warned during a prior DUI proceeding that drunk driving can constitute murder had implied malice when they chose to drive under the influence again and someone died.

A second-degree murder conviction under this theory carries 15 years to life in state prison compared to a maximum of 10 years under PC 191.5(a). Challenging the Watson elevation requires demonstrating either that the prior Watson admonishment was not properly administered, that the defendant did not have actual notice of the warning, or that the circumstances of the current offense do not support the implied malice theory. Our firm analyzes Watson murder exposure in every DUI-related death case from the first day of representation.

Gross Vehicular Manslaughter While Intoxicated Sentence

A conviction under PC 191.5(a) carries:

  • 4, 6, or 10 years in California state prison
  • Fines up to $10,000
  • Mandatory restitution to the victim’s family
  • Permanent revocation of driving privileges
  • Permanent felony record affecting employment, professional licensing, housing, and immigration status
  • Loss of firearm rights
  • For defendants with prior DUI convictions: potential Watson murder exposure carrying 15 years to life

Felony probation is not available under PC 191.5(a) when the defendant has certain prior DUI convictions. For first-time offenders without a Watson prior our firm presents the strongest possible case for probation as an alternative to state prison while simultaneously building the full defense.

How Our Firm Defends PC 191.5(a) Charges in Los Angeles

Challenging Gross Negligence

The most critical defense issue in most PC 191.5(a) cases is whether the driving conduct constituted gross negligence or only ordinary negligence. Gross negligence is the line between 191.5(a) and 191.5(b) and the difference between 10 years in state prison and 3 years. Our firm works with independent accident reconstruction experts to analyze road conditions, vehicle speed, visibility, traffic patterns, and every other factor relevant to the driving conduct and presents evidence that the defendant’s behavior did not rise to the gross negligence standard.

Challenging the Intoxication Evidence

Our firm scrutinizes every aspect of the DUI investigation — the basis for the initial stop or contact, the administration of field sobriety tests, the calibration and maintenance records for breath testing equipment, and the chain of custody for blood samples. When the blood alcohol evidence was obtained through improper procedures or when the testing methodology is unreliable our firm challenges the intoxication element directly. Without reliable intoxication evidence the prosecution cannot support a PC 191.5 charge.

Causation Defense

The prosecution must prove the defendant’s conduct was the proximate cause of the victim’s death. When another driver’s actions, road conditions, a vehicle defect, or the victim’s own conduct contributed to the collision our firm presents independent forensic evidence to challenge whether causation can be attributed solely to the defendant.

Blocking Watson Murder Elevation

When the prosecution attempts to charge second-degree murder under the Watson doctrine our firm challenges whether the prior admonishment was properly administered, whether the defendant had actual knowledge of the warning, and whether implied malice can be established given the specific circumstances of the case. Successfully defeating a Watson murder charge can reduce the exposure from 15 years to life to the PC 191.5(a) standard term.
