Case Study: Private Investigation
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.
