A 33-year-old woman is dead after a driver struck her in a crosswalk near the Hillcrest Avenue interchange with Highway 4 in Antioch and then fled the scene, leaving her car abandoned two miles away. Police are still searching for the driver, and the woman's name has not been released pending notification of her next of kin.
According to KTVU, Antioch police units were called to Hillcrest Avenue near Highway 4 just after 10:30 AM yesterday after reports of a woman down and unresponsive in the street. Officers arrived to find her critically injured; she was taken to a hospital, where she later died from her injuries.
Witnesses told police the vehicle had been exiting the highway when it struck the woman as she was in the crosswalk, the outlet reports. The driver did not stop to render aid or exchange information, instead fleeing the scene entirely. Investigators later located the vehicle involved, unoccupied, about two miles from where the crash occurred, but the driver remains at large as the investigation continues.
A Familiar and Dangerous Stretch of Road
The Hillcrest Avenue and Highway 4 interchange is a high-volume corridor where freeway traffic, local arterial streets, and a nearby BART station converge, and it has been the site of other serious crashes. In November 2025, a 63-year-old Antioch man riding an electric bicycle was critically injured near the same eastbound Highway 4 on-ramp at Hillcrest Avenue, according to The Antioch Herald.
Fatal hit-and-runs have also struck other parts of the city in recent months. Antioch police opened a separate fatal hit-and-run investigation in November 2025 after a fleeing driver killed a 60-year-old woman near Marie Avenue and East 18th Street. By contrast, a pedestrian killed in April 2026 at Country Hills Drive and Wolverine Way involved a driver who stayed at the scene and cooperated with officers, according to the Pacific Attorney Group — a distinction that matters under California law, since remaining at the scene can prevent felony hit-and-run charges even when a crash proves fatal.
What the Law Says About Fleeing a Fatal Crash
Under California Vehicle Code § 20001, drivers involved in a crash resulting in injury or death are legally required to stop immediately, exchange information, and render reasonable aid, regardless of who caused the collision, according to FindLaw. A conviction for fleeing a crash that caused death or permanent, serious injury carries two, three, or four years in state prison, or up to a year in county jail, plus fines between $1,000 and $10,000.
If prosecutors can also establish vehicular manslaughter, the penalties can grow steeper still. Under Vehicle Code § 20001(c) and Penal Code § 192(c), fleeing the scene after committing vehicular manslaughter carries a mandatory consecutive five-year prison sentence enhancement upon conviction, according to the Shouse Law Group. It remains unknown whether speed or impairment played a role in Saturday's crash, and the driver's identity has not been determined.
A Regional Pattern of Danger for Pedestrians
The crash adds to a troubling local and national pattern. Contra Costa County recorded 457 hit-and-run collisions resulting in injury or fatality in 2023, according to the California Office of Traffic Safety. Contra Costa Health reported in 2026 that four out of every 10 people killed or seriously injured in traffic collisions countywide are pedestrians or bicyclists, underscoring how vulnerable non-motorized road users remain on corridors like the one where Saturday's crash occurred.
The county adopted a Vision Zero Action Plan in 2022 aimed at eliminating traffic fatalities and severe injuries through roadway redesigns, speed management, and coordination among agencies. Nationally, pedestrian fatalities reached 7,080 in 2024, a 72% increase from a 2009 low and now representing 18% of all traffic crash deaths, according to an Insurance Institute for Highway Safety analysis of federal data.
Antioch police have not released a suspect description or vehicle details beyond confirming the car was found abandoned. The investigation into the fatal hit-and-run remains ongoing.
