Looking for a private investigator in Stockton? Bear Witness Private Investigators is a California-licensed firm (PI #18755) that has specialized in surveillance since 1996. Stockton is a city of about 320,000 people in San Joaquin County, and it is part of our regular coverage across Central Valley.

Stockton Surveillance Investigations: Our Specialty
Most investigations come down to one question: what is really happening? A private investigator in Stockton answers it with surveillance video, photos, and a written timeline.
Mobile Surveillance
We follow the subject by vehicle through Stockton 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.
Like much of San Joaquin County, Stockton mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
