If you need a private investigator in South Gate, Bear Witness has been documenting the truth for California clients since 1996. South Gate is a city of about 92,000 people in Los Angeles County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.

South Gate Surveillance Investigations: Our Specialty
As a South Gate 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 12,700 people per square mile, South Gate is dense — tight parking, slow traffic, and subjects who often move on foot. Our investigators plan for that.
