What is the difference between a detective and an investigator?

Two different things.
Detective is a term typically used to refer to police work, popularized by old Hollywood films and serial novels. In the private sector, the term investigator is more commonly used.

Martin Investigative Services is a full-service investigative agency composed of highly regarded and very experienced private investigators. All of our investigators are licensed by the state in which they operate.
Former Federal agents.

At Martin Investigative Services, we hold ourselves to the standard of providing the best possible service and treating our clients with the utmost respect, understanding, and confidentiality.

What is more important: The cost, or the end result?
There are many individual private investigators in the United States, and for some situations their services can be both effective and relatively inexpensive. But for personal or professional issues that may directly impact the remainder of your life, your family, or your financial future, ask yourself what is more important to you: the cost or the end result.

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.
