Inter-state helped me with a personal matter. They were highly effective, professional and got the job done. If you are in need of investigative services, this is the best place to go.

I am an attorney practicing criminal defense in Tucson. Having an outstanding private investigator is essential to my business. I could not run my practice without one. I have been working with Inter-State Investigative Services for over a decade. I use them to locate and interview witnesses, to do background checks on witnesses for the other side, photography work, and other services. They perform everything that an outstanding investigative service should to achieve the quality of service I seek to provide my clients. There are several reasons why, for me, Inter-State Investigative Services is really the only choice. Foremost, is their reliability and professionalism. When they tell me that they have identified a witness, testimony, or other evidence that relates to my case, I know that I can count on it. When I need an investigator from Inter-State Investigative Services to testify at trial to present their work, it will be done in a professional manner. Their work is always timely. If I give them a deadline, they will meet it. They provide information to me in memos that are well written and in exactly the format that I like. Inter-State’s billing is fair and reasonable. In those rare circumstances when I have had a question about a bill, they have been willing to discuss it with me and reach a reasonable resolution. If you need an investigator in Southern Arizona, Inter-State Investigative Services is the only choice. Michael J. Bloom

These guys are great! I worked with the Tucson office and specifically with Randy and Lisa - both provided honest feedback and kept me up to date on the work I had requested. Though the situation was not pleasant, they were able to push through and find the information and details I needed from them. They were both always pleasant, professional and cost effective. If you need investigate work performed, I recommend Inter-State Investigative Service above all others I have had to use in the past! Especially Randy and Lisa!!!

We highly recommend Inter-State Investigative services. Randy Downer and his team were attentive and prompt at identifying the problem. Not knowing what to do, they guided us expertly through a very difficult situation with a quick professional manner. Their surveillance was efficient, stealthy and successful in capturing the images we needed to present in court. They obtained documents, conducted interviews, and summarized the findings. Randy and his staff eased our anxiousness with empathy and efficiency in responding to all of our calls and emails. The work and the evidence Randy's team produced made the difference in our case. We will be eternally grateful to Inter-State Investigative Services.

During the 30+ years that I practiced law, I used this investigative team exclusively. I used them for significant matters (such as surveillance, witness interviews, scene diagramming and photographing) as well as minor matters (such as finding a witness). This company is simply top notch. I was never tempted to try a different investigative company. The work was always completed well in advance of my due date, the assigned investigator always followed up to make sure I had received all the information I needed, and their fees were always reasonable. This company truly understands customer service.

I am a criminal defense attorney who has worked with Mr. Downer and his agency for 25 years. We have done scores of cases together, virtually all of them involving the most serious criminal charges. Inter-State Investigative Services is the most competent, thorough and effective investigative agency in Arizona, bar none. The employees are committed to a successful outcome in the cases they handle and their ability to identify legal issues and to pursue facts relevant to those issues is unparalleled. I recommend this investigative agency without reservations.

Chris Chaffon

Real deal here. The team here is incredible, professional, caring and won't stop until the job is done. I have used them several times and they are the best you can get. I owe them a lot and highly recommend!!!!

Josh Hamilton

I am a criminal defense attorney practicing in Tucson and have worked with Inter-State for nearly 10 years and counting on dozens and dozens of cases, many of them high-profile. I have truly lost count of how many cases have been resolved successfully because of the work of Randy Downer and his entire team. There is simply no finer private investigative firm in Arizona. I simply cannot give them a higher recommendation.
