Ross Private Investigator Services, Built Around Surveillance
If you need a private investigator in Ross, Bear Witness has been documenting the truth for California clients since 1996. Ross is a town of about 2,600 people in Marin County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
Our Ross clients include individuals facing infidelity or a missing family member, parents in custody and support disputes, employers and insurers dealing with fraud, and law firms that need evidence and testimony. What they share is a need for discreet, lawful surveillance that holds up.
Ross Surveillance Investigations: Our Specialty
As a Ross private investigator, surveillance is the core of what we do. We document activity legally, discreetly, and in a way that holds up in court.
Mobile Surveillance
Experienced drivers who anticipate turns and freeway exits, so your subject is documented from stop to stop.
Static Surveillance
Discreet observation of a home, workplace, or business from a lawful public vantage point, documenting who comes and goes.
Two-Investigator Teams
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
In a community of about 2,600 people, an unfamiliar car gets noticed quickly. We keep observation windows short and well planned.
