Your Concord Private Investigator for Surveillance and Investigations
Bear Witness is the private investigator in Concord that families, attorneys, and businesses call when they need facts, not guesses. Concord is a city of about 124,000 people in Contra Costa County. We are a veteran-owned, California-licensed firm (PI #18755), and surveillance is what we do best.
Whether you suspect a cheating spouse, need evidence for a custody or support case, are dealing with a questionable workers’ compensation claim, or represent a client who needs court-ready surveillance, our Concord investigators plan each case around the subject’s real routine and document it with time-stamped video.
Surveillance Specialists Serving Concord
Most investigations come down to one question: what is really happening? A private investigator in Concord answers it with surveillance video, photos, and a written timeline.
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
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
The average commute in Concord is about 33 minutes, so work-related surveillance often means following a route, not waiting at one address.
