What Drives a Private Investigator Seeking Truth in Complex Times
What Drives a Private Investigator? Seeking Truth in Complex Times At Inter-State Investigative Services, we’re often asked: “What does a private investigator actually do?” and “Why do you choose this line of work?” While popular media may lean on dramatics such as surveillance vans, car chases, or dark alley stakeouts, … Continue reading

Translating Spanish Interviews in Private Investigations
In the field of private investigations, accuracy and clarity are everything – especially when interviewing witnesses who speak a language other than English. When a witness interview is conducted in Spanish, the process of translating that interview into English must be approached with care, precision, and cultural sensitivity. Why? Because … Continue reading
FAQs
Surveillance Misconceptions
The amount of evidence required to prevail in court is often the biggest surprise to clients.
In some cases, this can be even more true than others. In child custody cases, for example, it’s not enough to catch your ex-wife or husband in a single act of bad parenting. Rather, you need to establish a pattern of behaviors to convince the Court.
Painting this kind of picture can require much more surveillance than most people think. In fact, surveillance is largely a waiting game and it can take several attempts just to make one successful observation.
What is your role as a client?
Your role is to share as much information as possible with your investigative team. The more information you can share, the better. It makes the investigation more efficient and saves you money.
Additionally, you should be as proactive as possible, although always in consultation with your investigative team, and your attorney if you have one. Certain types of information will be more readily accessible to you than it will be even to the most seasoned, professional private investigator. Family medical and financial records, for example, may be easier and faster for you to obtain than for a third party like a PI.
We’ll discuss these issues in detail during your free consultation and help you come up with a list of ways that you can help in your investigation.
Can you find my long-lost friend or family member?
Probably, yes.
However, the more pertinent question here, for many clients, is: what can we do with the information?
If we are working with an attorney in preparation for litigation, then we can disclose certain information to the attorney in order to facilitate litigation. However, in private cases that are not connected to litigation privacy laws and ethical guidelines prevent us from finding a person and telling you their location. It may come as a surprise from a private investigative agency, but avoiding the invasion of other people’s privacy is a big concern for us, and we are proud to be a highly ethical agency.
Nevertheless, we are always happy to find a person and then initiate contact on your behalf. In other words, with your permission, we can give someone the means to contact you.
More often than not, acting as an intermediary and facilitating contact results in a successful connection between the client and the subject of the investigation.

Testimonials
I got a phone call from **** tonight – he said **** and he decided to DECLINE to issue criminal charges against our client related to the fatal shooting last month.
Case dismissed.
I called the client and let him. He broke down in tears and sobbed. I told him to have a very Happy Thanksgiving this year. He thanked us all profusely. He said he and his family will be saying cheers in our name tomorrow over their meal. Once again, most excellent work on this case team. Very proud to be a part of it!
J.F.H.
FYI – The attorney was very impressed with how quickly you got M*** served yesterday. … You guys make me look good by using you, so I REALLY appreciate it!

Thank you all so much for your hard work on this case and for working towards this great resolution. Our client is happy and is grateful beyond words for the work we did on his behalf
R.A.C.
I wanted to thank you personally for your excellent work in this case. I could not have obtained this dismissal without you. Chalk this one up as yet another victory when my firm teams up with Inter-State. I’ve lost count of how many victories we’ve obtained together, as a team, and I can’t wait until we get the next one
You should be very proud of the work you did in the E* case. Because of you, E* is a free man and will not have to continue to live with this terrible cloud looming over his entire life over some nonsense allegations spouted off by a lunatic. Your time and effort was what made all the difference to the ultimate outcome. Job well done
J.F.H.
A special thanks should go to Randy and Lacee and their team at Inter-State. This declination is quite frankly a direct result of the incredible investigative work they did in this case. They are without a doubt in my mind the very best in the business and J**** was lucky to have them on his team.
J.H.
My pleasure Randy, you guys always do a good job for me at reasonable prices. I send others your way too, I hope they occasionally drop my name!
C.G.
I almost don’t even know what to say. Thank you, all so much. There is no way that we would be to this point without all of your hard work and countless hours spent on me, and I appreciate you all more than you could know. I sincerely hope this is the end of it for all of us. Thanks.
N.S.
I got all the documents and am very impressed with the quality of your work. Thank you so much.
C.W.
You bet, Randy, I would recommend you for anything, anytime, anywhere, anyhow! You are the go-to guy!
D.G.
We’ll certainly turn to Inter-State Investigative Services whenever we have a need for investigations and/or surveillance anywhere within your service area. Please let me know how I can otherwise give your business a boost and call attention to your incredible commitment to customer service, etc.

My pleasure Randy, you guys always do a good job for me at reasonable prices. I send others your way too, I hope they occasionally drop my name!
C.G.
Thank you for your quick response and excellent work, as always. I always know my clients are in good hands with you.
N.H.
I want to express on behalf of Ralph and me how delighted we are with what you did in this case and have done in so many others. To get these cases dismissed prior to an arrest is so critically important to the client as he/she tries to get on with his/her/their life. Your hard work and dedication to the clients makes you more valuable to their cases than anything an attorney can do at this stage. You are all, each and collectively, invaluable assets to the criminal justice process and I hope to see you appropriately recognized as such. Again, our heartfelt thanks.
R.L.
Randy, thank you to you and your team for working hard on this. I know some cases are easier than others and this might be on the difficult side. So, I want you and your team to know how much I appreciate everything.

Randy…………. Sometimes I look back at my life and think of the people who have truly helped me or a family member. You are always at the top. I have referred others to you, and I tell the story of how you were able to call a hospital in Texas and determine that a sonogram was a fake.
A.C.
Thanks Randy. Your help is greatly appreciated…………..Great work!
