Inter-State Investigative Services

Fantastic experience: Randy, Lacee and ISII team were amazing to work with regarding a delicate family matter. In addition to their professional investigative services, they became involved as an advisory consultant, making recommendations that enabled us to accomplish our objective efficiently and effectively, while communicating with us regularly and demonstrating the necessary patience to ensure the best possibility for a successful outcome. We relied on Randy’s team as our eyes and ears, and it could not have gone any better. In a day of business shortcuts and money-grabbing, we felt comfortable and reliant on their good judgment and actions. It was a wonderful experience. Thank you, Randy, Lacee and ISII team.

Fantastic experience: Having worked with Inter-State for numerous years I cannot begin to tell you how great they are. Their services are at the top when it comes to professionalism, ethics, and making sure their clients are taken care of. The owner and his superior staff are incredible in their profession. They treat clients with respect, professionalism and are beyond patient. The response time is fantastic, their documentation is superb, and the quality of data is high. The work product and end results are always amazing. Our office will continue to use their services. I highly recommend Inter-State for any job.

Fantastic experience: Hands down the best there is. Randy is amazing and very detailed. I have been in the legal industry for over 25 years and no matter what state I have moved to his skills and services have proven to be priceless. 5-Stars just does not represent the amazing service they provide.

Fantastic experience: When I found out I was dealing with a con artist in a real estate transaction, the investigators at Inter-State were knowledgeable, professional, and considerate of my situation. They were able to research the scammer's background, and helped me to uncover the truth about her. If you are ever in the unfortunate situation of needing a private investigator, Randy, Jonathan and Mathew are the best. In my case, it was an investment worth making.

Fantastic experience: Inter-State Investigative Services served me exceptionally well. The staff provided the information I needed to contact a beneficiary to an estate. Prior to engaging Inter-State, I searched extensively on-line (spending significant money) for the contact information only to be disappointed with inaccurate and time-consuming information. If I simply worked with Inter-State Investigative Services initially, I would have saved a significant amount of time and frustration. I recommend them without hesitation.

Fantastic experience: Excellent service. Great communicators. Just a brilliant team all around!

Thank you Randy and everyone that works on this team you are greatly appreciated.

Fantastic experience: With Inter-State Investigative Services help, I was able to successfully locate and serve legal papers to someone for a civil case.

Fantastic experience: Interstate has produced the utmost highest quality of work and displayed extreme professionalism throughout my experience of working with them. I would STRONGLY recommend them to anyone in need of PI services.

Fantastic experience: Behind every great lawyer, there's a great investigative team. That's the case of Inter-State Investigative Services (IISAZ), the best agency behind Arizona's most respected criminal attorneys. I was falsely accused of a felony and hired the best attorney for my case. In fact, I hired a team of attorneys and investigators that worked tirelessly and effectively in my case. The first time I met Randy Downer, President of IISAZ, I knew I had met the best in the field. Courteous and direct, he assured me with actions that would deliver vital information for my case. In a matter of a couple of weeks, IISAZ revealed the facts that would, in time, form the foundation for my innocence. Randy assigned Investigator Lacee Tellez to execute the research work on my case. She dug deeper than the prosecution during the discovery process. She found many facts and police reports about the accuser's family that should have persuaded any good police detective to take a closer look at what was happening in the accuser's house in the first place. As IISAZ's investigation progressed, the prosecution’s case became weaker and weaker. My lawyers took full advantage of crucial information and the leads that Ms. Tellez and the team accumulated. The information provided was presented at the hearings, revealing inadmissible evidence, fabricated scenarios, false testimonies, and even witness perjury. Then, a crucial piece of evidence came into the hands of IISAZ and my lawyers. Information from another case indicated a pattern of suspicious communications between police detectives and accusers that weren't disclosed during discovery, indicating collaboration to inflame evidence to help the prosecution’s case. IISAZ immediately requested all the communications between accusers and the police, and in disgraceful desperation, the police deleted all messages. This heinous act triggered the dismissal of my case. As unique as all this sounds, this story wouldn't have been possible without IISAZ's investigative resources, the team's tireless dedication, and Randy's leadership. I'm forever profoundly grateful to this team. A few days after the court dismissed my case, I visited for the first time IISAZ's headquarters. I was very impressed by the investigative and professional resources they provide to their clients. Most importantly, I was totally surprised by how familiar all of them were with my case and by what good listeners they are. If you or your lawyer need investigative services that are time efficient, meticulous, and effective, I highly advise you to contact IISAZ. They will gather not only the information that you need, but they will also work tirelessly to reveal the truth. I assure you that your peace of mind and future are in good hands with them.

Fantastic experience: Randy and Lacee pulled out all the stops for me, and I can't understate this: they are saving my life, if they haven't already. They dug deeper and more critically than the authorities to find the truth and the very questionable histories that exist. They will FIGHT for you. They turn every stone. Thank you Randy and Lacee.

Fantastic experience: Brandy and her team worked tirelessly to get the paperwork signed and notarized with the utmost professionalism . I would highly recommend them to anyone needing special services. They also had the best pricing for their work.

Fantastic experience: Randy and his team have always provided professional and accurate information with cases. They provided excellent information and communicate with me as soon as information becomes available. I appreciate all their hard work and dedication provided by Inter-State Investigative Services. This is an office that goes above and beyond for their clients. Thank you for always being in my corner :)

Fantastic experience: 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!!!

Fantastic experience: 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!!!!

Fantastic experience: Very caring and professional. Would recommend them without hesitation to anyone needing their services!

Fantastic experience: 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.

Fantastic experience: Very quick, communicates well, and points you in the right direction if there's more needed.

Fantastic experience: 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

Fantastic experience: Professional, confidential, get results.

Fantastic experience: 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.

Fantastic experience: Very professional and knowledgeable staff!!!

Fantastic experience: 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.
