    Cheating spouse?


    Private investigation to catch a cheating spouse

    In our surveillance section, you'll see how we can help catch a cheating spouse in the act. You'll know the truth, but equally important are the legal implications. Proof can help save you money, help with child custody, and undue burden during legal / divorce proceedings.



    Need a bug sweep?


    Bug sweeps help detect listening and video devices.  This is a wireless camera and received we actually discovered.

    In our bug sweeps section, you'll learn about the signs you could be bugged, and the bug sweeps we perform when you suspect your office or business has been compromised.

Case Study: Private Investigation

Private Investigation Case Study

Orange County Murder Cold Case



We first met our client through a conference call with the client's family and their attorney, a prominent Orange County attorney.

The client strongly believed that her friend was shot and murdered by her husband. Local police had concluded the case was an accidental shooting.

Results:
After a 9-month investigation, our private investigators gathered enough evidence to prove our client's suspicions were correct. We turned our evidence over to the Orange County District Attorney and the husband was arrested.

Martin Investigative Services has investigated hundreds of cold cases like this one. If you need our help, please contact one of our private investigators us for a free, private consultation.
