Alhambra Private Investigator Services, Built Around Surveillance
Bear Witness is the private investigator in Alhambra that families, attorneys, and businesses call when they need facts, not guesses. Alhambra is a city of about 81,000 people in Los Angeles County. We are a veteran-owned, California-licensed firm (PI #18755), and surveillance is what we do best.
Our Alhambra clients include individuals facing infidelity or a missing family member, parents in custody and support disputes, employers and insurers dealing with fraud, and law firms that need evidence and testimony. What they share is a need for discreet, lawful surveillance that holds up.
Surveillance Specialists Serving Alhambra
Most investigations come down to one question: what is really happening? A private investigator in Alhambra answers it with surveillance video, photos, and a written timeline.
Mobile Surveillance
We follow the subject by vehicle through Alhambra 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
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
Alhambra’s density (about 10,700 people per square mile) makes foot surveillance practical and keeping a vehicle in position harder, so we plan coverage accordingly.
