Your Muir Beach Private Investigator for Surveillance and Investigations
If you need a private investigator in Muir Beach, Bear Witness has been documenting the truth for California clients since 1996. Muir Beach is an unincorporated community of about 400 people in Marin County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
From infidelity and custody cases to workers’ compensation fraud and litigation support, we keep our caseload small so every Muir Beach client works directly with the investigator in the field — and gets a clear answer, documented to the standard California courts expect.
Muir Beach Surveillance Investigations: Our Specialty
Most investigations come down to one question: what is really happening? A private investigator in Muir Beach answers it with surveillance video, photos, and a written timeline.
Mobile Surveillance
We follow the subject by vehicle through Muir Beach and beyond, keeping distance and cover so they never know we are there.
Static Surveillance
Discreet observation of a home, workplace, or business from a lawful public vantage point, documenting who comes and goes.
Two-Investigator Teams
Team surveillance covers multiple exits and keeps a moving subject in sight in heavy Northern California traffic.
With around 800 people per square mile, Muir Beach offers fewer places to blend in and longer drives between stops — which is why planning matters so much here.
In a community of about 400 people, an unfamiliar car gets noticed quickly. We keep observation windows short and well planned.
