Livermore Teen Killed and Two Injured in Suspected DUI Crash on the Outskirts of Monterey

What the Monterey Police Reported

The Monterey Police Department said officers responded at about 5:14 p.m. on Sunday, August 16, 2026, to a crash near Barnett Segal and Iris Canyon roads on the outskirts of Monterey. Arriving officers found a convertible that had left the road and struck a tree.

According to police, the car was occupied by a driver and three passengers, and all four were hurt and taken to Natividad Medical Center. One passenger, identified by the Monterey County Coroner's Office as 19-year-old Jerrod Tyson Chapman-Marshall of Livermore, died as a result of the crash. The other two passengers had non-life-threatening injuries.

Police said the driver, a 20-year-old Dublin man, showed signs of impairment at the scene, and a preliminary alcohol screening indicated a blood-alcohol level above 0.13 percent. Officers said he would be booked into the Monterey County Jail on suspicion of gross vehicular manslaughter once he is released from the hospital. Investigators reported the vehicle had traveled from Carmel to Monterey and said the cause remained under investigation. A criminal charge is an accusation, and the driver is presumed innocent unless proven guilty.

Why a Passenger's Family Has Options After a DUI Crash

A passenger is generally not responsible for how a driver operates a vehicle. When a passenger is killed in a crash that police describe as a suspected DUI, the passenger's family may have a wrongful-death claim against the at-fault driver, separate from any criminal case.

This article does not decide the criminal case or assign final fault, which are matters for the courts and the investigation. It does note that the roles here are already fairly clear from the reporting: a passenger who was killed, and a driver who police say was impaired. That distinction often matters a great deal for a grieving family trying to understand its options.

A criminal case and a civil claim are separate and use different standards of proof. A family can pursue a civil wrongful-death claim no matter how any criminal case ends.

Evidence That May Matter in a Suspected DUI Case

Important evidence in a case like this can include the police report, any chemical test and preliminary alcohol screening results, scene and roadway evidence, the vehicle's event data recorder, damage and inspection records, coroner records, and statements from witnesses and the surviving passengers.

Because vehicles are moved and repaired and records can be delayed, preservation requests and timely inspection often matter. Where a driver is reported to have been drinking before a crash, the source of any alcohol can sometimes be part of a broader review, depending on the facts.

A California car accident lawyer can help a family request and preserve these records, follow the criminal case as it moves forward, and understand what a civil claim might involve after a fatal suspected DUI crash.

Options for Families After a Fatal DUI Crash

California allows the family of someone killed by another driver's conduct to pursue a wrongful-death claim. In a suspected DUI case, that claim looks at the at-fault driver's insurance and, where available, a family's own uninsured or underinsured motorist coverage.

These situations are painful, and every case depends on its own facts and on what the investigation and court process ultimately show. Nothing here is a promise about any specific outcome.

Families who have questions can speak with a lawyer about how the criminal case, insurance coverage, and the available evidence may affect their options, without any obligation.
