What the data shows in Marin County
Since January 2025, the Marin Rapid Response Network has counted 29 Marin residents detained by ICE. Many arrests happened at or after jail releases, or during ICE check-ins and court appearances in San Francisco.
Families in Sausalito, Larkspur, and Fairfax say they’ve felt the impact directly. It’s tough for them to know what to expect next.
Detentions tied to jail releases and check-ins
In March, ICE picked up two Marin residents after they left jail. Two more got detained just after their April releases.
April brought another wave—two men were seized and sent to a faraway ICE facility. That left people wondering where and how these arrests really happen.
- ICE transferred two men to the Golden State Annex in McFarland, a 700-bed detention center run by GEO Group. An attorney managed to speak with them before the move.
- One Marin woman got detained after she went to a USCIS office to give fingerprints for her work-permit application.
- In March, a Marin mother and her two kids were detained at a San Francisco check-in, flown to Louisiana, and deported to Guatemala within two days, family members said.
Community response and the network’s growth
The Marin Rapid Response Network, part of the Multicultural Center of Marin, has grown fast since early 2025. Now, it lists about 1,000 volunteer witnesses, 21 dispatchers, and two part-time staffers.
Communities from Mill Valley to San Anselmo, and Tiburon to Ross, are getting involved—documenting sightings and supporting families during detentions.
- Funding comes from a few sources: $125,000 from the San Francisco Foundation, $75,000 from the Marin Community Foundation, and $150,000 from Marin County.
- Even with these grants, leaders admit resources still fall short. The need for case management and accompaniment keeps growing in towns and neighborhoods all over Marin.
Volunteer training and safety guidelines
Volunteers do three hours of training and wear pink aprons so people know they’re legal observers. They’re told not to interfere with ICE agents, just to watch.
One local trainer hands out whistles and sends alerts—some made in Chicago with 3D printers—to warn people when ICE shows up in spots like Sausalito and San Rafael.
Local impact across Marin towns
When news of detentions hits the Marin County press, families from Novato to Corte Madera feel the stress. In Larkspur and Ross, people worry about the effects on kids and households, especially when parents can’t stick to school routines or after-school plans.
The network’s hotline tries to cut down the time families go without answers. Volunteers in Fairfax and San Anselmo help folks get to appointments and access basic services.
Sheriff’s perspective and policy context
Sheriff Jamie Scardina said he saw ICE in the jail lobby during two April releases, but the office couldn’t confirm arrests outside the jail. He pointed out that state law only lets them notify ICE for serious or violent felonies.
This policy makes it harder for Marin residents to track detentions in places like Marin City and Tiburon. It’s a complicated situation, and there aren’t easy answers.
How to stay informed or help
Community members across Marin—from Corte Madera to San Rafael and from Mill Valley to Sausalito—can take part in the network’s work. Everyone can find ways to engage and support:
- Call or text the Marin Rapid Response Network hotline to report ICE sightings or get information. This hotline is especially important for families in Ross and San Anselmo.
- Join as a volunteer witness, dispatcher, or supporter through the Multicultural Center of Marin. The program now depends on a growing pool of trained volunteers, including folks in Novato and Belvedere.
- Support funding and services that expand case management, legal accompaniment, and family assistance. These resources help communities from Fairfax to Bolinas during detentions.
Marin County faces a complicated landscape of immigration enforcement. The Marin Rapid Response Network gives people a way to document incidents, accompany families, and push for clearer procedures that protect vulnerable residents in towns like Mill Valley, Corte Madera, and Larkspur.
