A 41-year-old Novato woman has been charged with murder and gross vehicular manslaughter with intoxication after a crash that killed her 61-year-old mother. Kenia Marcela Alegria was allegedly driving with a blood-alcohol level over twice the legal limit when the crash occurred on Highway 101 near Petaluma on February 11, 2026. Alegria's mother, Teresa Renderos, was pronounced dead at the scene, while Alegria and another passenger were hospitalized.
Why it matters
This case highlights the tragic consequences of drunk driving, especially for repeat offenders. Alegria was on probation for a previous DUI conviction in Marin County in 2023 when the fatal crash occurred. The murder charge reflects the severity of the incident and the legal system's efforts to crack down on impaired driving.
The details
According to prosecutors, Alegria's blood-alcohol level was 0.20% or more at the time of the crash, more than twice the legal limit of 0.08%. She was prohibited from driving with any alcohol in her system due to her prior DUI conviction. Alegria did not enter a plea during her initial court appearance and is being held without bail at the Sonoma County Jail.
- The crash happened on February 11, 2026 on Highway 101 near Petaluma Boulevard South.
