Here are a few real-life examples of recent private investigation cases we've had in Orange County:
Orange County Case Study:
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 into an otherwise cold case, 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. Contact us for a free, confidential consultation.
Orange County Case Study:
Cheating Spouse Case
A wife, and mother of three children, met with us in one of our Orange County offices. She suspected her husband was cheating on her but she needed proof.
Results:
Our private investigators performed a minimum 4-hour surveillance on her husband. We provided video of her husband and his lover going to a local hotel.
We referred the client to one of our preferred attorneys who assisted in obtaining a divorce decree.
