San Gabriel Private Investigator Services, Built Around Surveillance
If you need a private investigator in San Gabriel, Bear Witness has been documenting the truth for California clients since 1996. San Gabriel is a city of about 39,000 people in Los Angeles 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 San Gabriel client works directly with the investigator in the field — and gets a clear answer, documented to the standard California courts expect.
Why Surveillance Is at the Heart of Every San Gabriel Case
As a San Gabriel 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
We hold position at the locations that matter to your case and record activity with time-stamped video.
Two-Investigator Teams
Team surveillance covers multiple exits and keeps a moving subject in sight in heavy Southern California traffic.
At roughly 9,400 people per square mile, San Gabriel is dense — tight parking, slow traffic, and subjects who often move on foot. Our investigators plan for that.
