La Puente Private Investigator Services, Built Around Surveillance
Bear Witness is the private investigator in La Puente that families, attorneys, and businesses call when they need facts, not guesses. La Puente is a city of about 37,000 people in Los Angeles County. We are a veteran-owned, California-licensed firm (PI #18755), and surveillance is what we do best.
From infidelity and custody cases to workers’ compensation fraud and litigation support, we keep our caseload small so every La Puente client works directly with the investigator in the field — and gets a clear answer, documented to the standard California courts expect.
La Puente Surveillance Investigations: Our Specialty
As a La Puente 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
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
La Puente’s density (about 10,800 people per square mile) makes foot surveillance practical and keeping a vehicle in position harder, so we plan coverage accordingly.
