What We Investigate
Here’s an overview of our investigation categories. Each is handled by licensed professionals trained in California law, evidence handling, and surveillance compliance.
Infidelity Investigations
Suspect your partner is cheating? Our Sacramento-based PI firm uses surveillance, digital forensics, and GPS tracking (where permitted) to provide proof—and peace of mind.
Child Custody Investigations
When custody or visitation is at stake, the truth matters. We gather evidence on parenting behavior, home environment, and more to help you protect what matters most.
Workers' Compensation Investigations
We help employers identify fraudulent claims, verify injury reports, and gather surveillance to support fair case outcomes.
Cohabitation Investigations
If your ex is living with a romantic partner while receiving spousal support, we collect the evidence needed for potential support modification under California Family Code § 4323.
Criminal & Civil Investigations
Whether you need help recovering stolen property, verifying witness statements, or supporting civil litigation, we handle both sides of the legal aisle with professionalism and skill.
Bug Sweeping / Technical Surveillance Countermeasures (TSCM)
We detect hidden microphones, GPS trackers, and wireless cameras in homes, offices, and vehicles using cutting-edge RF scanning and physical sweeps.
Polygraph Testing
We offer professional polygraph testing by certified examiners in a controlled environment—ideal for legal disputes, HR conflicts, or personal resolution.
Surveillance
From cheating spouses to workers’ comp fraud, our covert surveillance teams use video, high-resolution photography, and vehicle tracking to document facts discreetly and legally.
Background Checks
Avoid risky hires or personal entanglements with in-depth reports on criminal history, financial activity, employment verification, and more.
Process Serving
When legal documents need to be delivered to evasive individuals, we serve papers professionally, discreetly, and in full legal compliance.
