Story Snapshot
- Fairfield police believe foul play is involved in Brooks’s disappearance.

- Brooks was last seen in Fairfield after leaving work in San Francisco on July 17.
- Her black 2021 Infiniti was later flagged by a license plate camera in Oakland.
Police move case into foul play after intensive investigative work
Fairfield Police Department officials said their investigators believe foul play is involved in the disappearance of 36-year-old Chantel Brooks. Lieutenant Kelly Rombach said the department remains in active investigation status and based this conclusion on findings developed so far.
Detectives did not reach that view lightly. They obtained dozens of search warrants, organized coordinated ground searches with rescue teams, and ran extensive aerial drone grid sweeps. That level of effort signals a serious criminal inquiry, not a routine welfare check.

Investigators also coordinated with the Solano County District Attorney’s Office. That step brings prosecutorial eyes into the loop early, which helps shape warrant work, evidence handling, and charging decisions down the line.
The department released case contact details and urged the public to share any tips about Brooks or her vehicle tied to case number 26-7208. Police have not, at this time, shared the specific facts that led to the foul play assessment, a common move while evidence is being developed.
Timeline centers on late-night movement from San Francisco to Fairfield
Reporters placed Brooks’s last known movements on July 17. She finished a shift in San Francisco and was later seen in Fairfield. Surveillance showed her approaching her vehicle in a CVS parking lot on East Travis Boulevard at about 1:45 a.m.
That sighting anchors the public timeline and fixes location and time near a busy corridor with cameras and traffic. That kind of timestamp becomes the spine of a case map when police reconstruct final hours and routes traveled.
Police also tied the case to a specific car. They identified her black 2021 Infiniti sport utility vehicle and said a license plate camera later detected it in Oakland. The vehicle has not been recovered, raising the stakes and expanding the search radius into the East Bay.
Automated license plate readers can narrow time windows and road choices, giving detectives leads on where to look next or who might have followed or used the car.
How investigators build a no-body foul play case
Detectives follow a proven playbook when someone disappears and a crime is suspected. They map the person’s routine, collect surveillance, pull phone and financial records, and interview anyone who crossed paths with the victim.
The Federal Bureau of Investigation (FBI) teaches that in possible no-body homicide cases, reconstructing normal patterns is key to showing where and when they broke. That is why the San Francisco shift, the Fairfield CVS stop, and the Oakland camera hit matter so much together.

Search warrants also matter. They let police gather digital traces, car data, location points, and communications that can paint a coherent story. The agency’s reports of dozens of warrants and large-scale searches suggest they are testing a tight theory, not fishing. Public help remains vital. If a camera saw the car, a neighbor, a driver, or a store camera might have captured who was inside it.
What matters next and how the public can help
The most important next steps are locating the Infiniti, securing any new surveillance along the Oakland corridor, and expanding canvasses between the CVS lot and the camera hit. Police and prosecutors will keep refining the timeline, checking financial activity, and comparing phone movements.
Anyone who was near the Fairfield CVS around 1:45 a.m. on July 17 should contact police. Tipsters who saw the Infiniti in Oakland after that date should do the same. One memory can unlock a stuck case.
This case has the classic early markers of a foul play investigation: a defined last sighting, a missing vehicle with a later camera hit, and a heavy warrant footprint. Those signals do not tell the whole story yet, but they show where the story is heading. If you know something, call it in.
Police say they believe a crime occurred here, and the fastest way to justice and answers is clear, timely leads from people who saw even one odd detail.
