An East Bay man faces 11 criminal charges after what investigators describe as a horrifying sequence of events that began at a San Leandro temple and ended with a high-speed crash near Ygnacio Valley Road in Walnut Creek. The case has drawn attention to the lethal intersection of domestic violence, impaired driving, and the dangers police pursuits pose to East Bay communities.
The Timeline: From Temple Confrontation to Fatal Crash
On the morning of January 26, 2026, worshippers at Temple Beth Sholom in San Leandro arrived to find bloodstains outside the building. According to court records, witnesses reported seeing a confrontation between 37-year-old Miriam Patricia Avila, who worked at the temple, and 32-year-old Humberto Guevara, her former partner. Guevara had been ordered by a judge to stay away from Avila following allegations of domestic violence.
Witnesses told police they saw Guevara run over Avila with a 2008 Volkswagen Golf before forcing her into the vehicle and driving away. Over the next 90 minutes, the two traveled through the Tri-Valley area, passing multiple hospitals without stopping. Avila, according to Guevara’s own statement to police after his arrest, began asking, “What are we doing here?” and “I don’t want to be here.”
The sequence ended catastrophically around 9:20 a.m. on Vasco Road in Brentwood, when the Volkswagen suddenly swerved from an eastbound lane into westbound traffic and collided head-on with a box truck. A passing motorist who stopped to help found Avila trapped inside the wreckage. Moments later, he saw Guevara stumbling away from the crash scene, his pants at his ankles, before the suspect allegedly stole the Good Samaritan’s Honda Accord and fled.
A Police Chase Through Contra Costa County
What followed was a dangerous pursuit that wound through Contra Costa County’s highways and surface streets. Guevara allegedly attempted to ram police vehicles multiple times, drove the wrong way down an Interstate 680 offramp, and reached speeds of 120 miles per hour before crashing the stolen Honda into a center divider near Ygnacio Valley Road in Walnut Creek.
The Walnut Creek Police Department assisted in the final phase of the pursuit. A department spokesperson confirmed that officers helped secure the scene and coordinate with California Highway Patrol and Brentwood police, who had initiated the pursuit.

Avila’s Family and the Human Toll
Avila languished at a Bay Area hospital for three days before being declared dead from the crash. During that time, her family frantically tried to reach her, unaware of the violent chain of events that had unfolded. By the time authorities connected the bloodstains at Temple Beth Sholom to the fatal crash on Vasco Road, the full picture of what happened became chillingly clear.
Avila was remembered by colleagues at Temple Beth Sholom as a dedicated worker and a kind presence in the community. The temple has declined to comment publicly on the case, citing the ongoing criminal proceedings.
Legal Proceedings and What Comes Next
Guevara has been charged with 11 counts, including vehicular manslaughter, assault with a deadly weapon, fleeing the scene of a crash, car theft, assault on a peace officer, evading police, hit and run, driving on a suspended license, and violating a protective order. He is next due in court in August 2026 for a preliminary hearing, where a judge will review the evidence against him.
According to police reports, Guevara appeared to be under the influence of a stimulant during his post-arrest interview. His statements to investigators were described as disjointed and inconsistent. The Contra Costa County District Attorney’s Office is prosecuting the case.
Key Case Details at a Glance
The case has drawn attention to the intersection of domestic violence enforcement and high-speed police pursuits, both topics under active review by Bay Area law enforcement agencies. If convicted on all counts, Guevara faces a sentence exceeding 20 years in state prison.
| Charge | Count | Severity |
|---|---|---|
| Vehicular Manslaughter | 1 | Felony |
| Assault with a Deadly Weapon | 1 | Felony |
| Evading Police / Fleeing Scene | 4 | Felony / Misdemeanor |
| Car Theft / Assault on Officer | 3 | Felony |
| Violating Protective Order | 2 | Misdemeanor |
Broader Implications for East Bay Public Safety
This case underscores persistent challenges in protecting domestic violence survivors from escalating threats. Despite a standing protective order, Guevara allegedly located Avila at her workplace and the confrontation turned deadly. The Contra Costa Family Justice Center reports that violations of protective orders remain one of the most common referrals they receive, and cases involving vehicular assault are on the rise regionally.
Law enforcement pursuit policies are also under scrutiny. The California Highway Patrol’s pursuit guidelines were updated in 2025 to require a balancing test between the danger posed by the fleeing suspect and the risk to the public. The Walnut Creek Police Department’s own policy, last revised in 2024, authorizes pursuits only when the suspect poses an immediate threat and the pursuing officer maintains continuous communication with dispatch.
For Walnut Creek residents, the incident is a reminder that serious crime can reach any community. The crash site near Ygnacio Valley Road and I-680 is less than two miles from downtown Walnut Creek, in an area frequented by families heading to Heather Farm Park and shoppers visiting nearby retail centers.
The Contra Costa County District Attorney’s office has not indicated whether additional charges may be filed. The preliminary hearing, expected in August, will determine whether there is sufficient evidence for the case to proceed to trial. Updates to this story will be published as court proceedings develop.
