Pasadena Private Investigation Services: Cases We Handle

Every case our Pasadena private investigators take on has a clear objective, and we provide documentation that clarifies your situation.

Some of our most requested services include:

Surveillance

Need proof of someone’s movements or actions? Our team conducts surveillance to document routines, interactions, and behavior. Clients often hire us to investigate executive-level job applicants, monitor custody exchanges, or verify insurance-related claims. We use lawful tactics and discreet equipment to gather photo and video evidence without alerting the subject.

Infidelity and Relationship Concerns

Do you suspect your partner hasn’t been honest? Our infidelity investigators in Pasadena​ provide factual reports that confirm or disprove concerns. This may include tracking whereabouts, observing interactions, or documenting behavior patterns over time. You’ll receive photo and video evidence along with detailed logs.

Background Checks and Asset Searches

Do you need to verify someone’s history or finances? We run detailed background investigations that include criminal records, civil filings, business affiliations, liens, and asset ownership. These checks help clients make informed choices before hiring, signing contracts, or entering personal agreements.

Surveillance and Pattern Verification

In cases involving injury claims, custody disputes, or HR concerns, our surveillance work captures movement, routines, and interactions in a way that holds up under scrutiny. We use advanced optics, secure video logging, and field tactics tailored to the environment.

Fraud and Theft Investigations

Are you dealing with financial losses or suspicious activity? Our team investigates employee theft, embezzlement, false insurance claims, and billing or payroll fraud. From cases involving trusted staff to vendors or outside parties, we gather the evidence that supports disciplinary action, legal steps, or insurance disputes without unnecessary delay.

Missing Persons and Witness Locates

Need help finding someone who’s gone off the radar? We locate hard-to-find people, whether they’ve dropped out of contact or are intentionally avoiding being found. This includes missing family members, former partners, debtors, or witnesses in legal claims. Our investigators use public records, digital tools, and on-the-ground research to track them down and have a 95% success rate.

Litigation Support

Building a case and need reliable documentation? Attorneys and legal teams rely on us to gather information that holds up in court. This includes witness interviews, asset verification, surveillance, background investigations, and service of process in hard-to-reach cases. We work discreetly, meet deadlines, and provide organized, court-ready reports that support your strategy from pre-trial through resolution.

No matter your reason for hiring a private investigator, our local experience helps us work more efficiently and get the results you need to move forward.
