Your Rialto Private Investigator for Surveillance and Investigations
Looking for a private investigator in Rialto? Bear Witness Private Investigators is a California-licensed firm (PI #18755) that has specialized in surveillance since 1996. Rialto is a city of about 104,000 people in San Bernardino County, and it is part of our regular coverage across Southern California.
Our Rialto 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.
Why Surveillance Is at the Heart of Every Rialto Case
Most investigations come down to one question: what is really happening? A private investigator in Rialto 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
Discreet observation of a home, workplace, or business from a lawful public vantage point, documenting who comes and goes.
Two-Investigator Teams
Team surveillance covers multiple exits and keeps a moving subject in sight in heavy Southern California traffic.
The average commute in Rialto is about 33 minutes, so work-related surveillance often means following a route, not waiting at one address.
