Timeline of charges and court proceedings
After the Feb. 11 collision on Highway 101 near Petaluma, authorities reported that Alegria’s mother, Teresa Renderos, died at the scene. Detectives quickly started gathering evidence about Alegria’s behavior and condition right before the crash.
On March 5, the Sonoma County district attorney filed a second murder count for the death of Alegria’s aunt, Flor Vasquez, who died from her injuries on February 20. Prosecutors included a second count of gross vehicular manslaughter related to the same crash.
Judge Lynnette Brown ordered Alegria to return to court on March 26 to enter a plea and set a preliminary hearing. The case has become high-profile along the Sonoma–Marin County corridor, with people in towns like Novato and San Rafael watching to see how the DUI allegations play out.
What investigators say and the defendant’s status
The California Highway Patrol (CHP) report lays out several key details in the criminal complaint. Officers say both victims weren’t wearing seatbelts and got thrown from the BMW Alegria was driving.
CHP investigators allege Alegria was under the influence of drugs or alcohol during the crash. Evidence collected at the scene and hospital backs up that claim.
Alegria’s blood-alcohol content on Feb. 11 was at least 0.20, well over the legal limit of 0.08. She got injured in the crash and police arrested her about a week after she left Providence Santa Rosa Memorial Hospital.
Officials mention a prior DUI arrest in January 2022. Alegria pleaded guilty and got three years’ probation, with a condition not to drive after drinking.
Prosecutors say this prior record influenced their decision to pursue a murder charge, given her history of impaired driving. The case so far has focused on the crash’s outcomes and how the law handles fatal DUI incidents along the Marin County and Sonoma County corridors.
Marin County context and community impact
From Novato to Mill Valley, families along the 101 corridor talk often about road safety and the fallout from impaired driving. The Highway 101 route through Marin and neighboring counties is a lifeline for daily commutes to jobs in San Rafael and Petaluma.
Incidents like this crash spark conversations in local coffee shops from Larkspur to Corte Madera. In Novato, neighbors know the risks and the constant need to keep families safe.
In San Anselmo and Fairfax, residents discuss enforcement, outreach, and what authorities do when a DUI case turns tragic. The case also echoes in Marin City and across the county, where law enforcement and prosecutors remind people that impaired driving can have devastating, irreversible consequences for families in towns like Santa Rosa and Rohnert Park.
Local coverage in Marin focuses on the human side—families, neighbors, and first responders left to deal with the aftermath of a crash that took a mother and an aunt far too soon. Community leaders in San Rafael and the Marinwood area urge residents to use designated drivers and sober transportation options.
Those steps are still essential for keeping Highway 101 and the surrounding streets safer for everyone.
What’s next in the case
The court’s still set on the March 26 appearance for a plea. That’ll happen in the Sonoma County Superior Court.
If Alegria pleads to the murder and gross vehicular manslaughter charges, things move into pretrial. The defense and prosecution will start laying out their evidence and arguments, possibly teeing up for a trial.
Meanwhile, folks from Novato to Petaluma—and honestly, anyone along the Marin–Sonoma corridor—are watching. This case hits a nerve, sitting right where public safety, personal responsibility, and community impact all tangle up on the 101.
