TB Defense is a licensed private investigation agency in Chicago that helps law firms, insurance companies, large corporations, small businesses, and private citizens get clear, lawfully gathered answers to specific questions. Led by career Chicago Police investigators, our team works locally, nationally, and internationally, and scopes every engagement, large or small, to the question it needs to answer.

What a private investigation includes

  • Legal and litigation support for attorneys and law firms
  • Corporate investigations into fraud, theft, and misconduct
  • Private investigations, surveillance, and background checks
  • Sensitive domestic and family matters, handled discreetly
  • Skip tracing, locates, and asset searches
  • Clear written reports that document what was found, and recorded statements taken with consent

How does a private investigation work?

Every investigation starts with a confidential consultation to define the question and the outcome you need. We scope the work to that question, keep you informed as it develops, and deliver findings in a clear written report. Where a matter may reach a court, an insurer, or an employer, we document methods, sources, and findings with that in mind from the start.

Who hires a private investigator in Chicago?

Attorneys, insurers, companies of every size, and private citizens in Chicago and beyond who need a professional, lawful, and discreet answer to a specific question. When the concern is a person threatening you or your company, protective intelligence may be the better fit; for missing loads and inventory, see supply chain and cargo security.

Our investigations draw on decades of Chicago Police detective work in homicide, organized crime, and digital and cellphone forensics; meet our leadership. In one engagement, David Dobrik asked us to locate a close friend who had gone to lengths to stay hard to find, and the matter was resolved that same day. See our clients.

Common questions

Who do you take cases for?

Large corporations, insurance companies, law firms, small businesses, and private citizens. We take matters large and small and scope each one to the question you need answered. We serve clients in Chicago and across Illinois, and our investigators also work nationally and internationally when a case leads there.

Will the findings hold up in court?

When a matter may reach a court, an insurer, or an employer, we document methods, sources, and findings carefully from the start so the work is ready for review by your attorney. Whether evidence is admissible is for the court to decide.

Are domestic investigations confidential?

Yes. We treat domestic matters as confidential, handle them discreetly and with compassion, and share findings with you, except where a subpoena, court order, or law requires disclosure. The first consultation is confidential too, so you can describe the situation and decide how to proceed before any work begins.

Do you handle investigations outside Chicago?

Yes. TB Defense is based in Chicago, and our investigators work locally, nationally, and internationally, including background research, surveillance, locates, and witness work that crosses state lines. Tell us where the people, records, or events in your matter are, and we will scope the investigation around the question you need answered.
