-Maureen Keefe

I had previously used two separate private investigators to find a relative. I think all they did was check public records - something I could have done myself. Tom Lauth, actually went out and interviewed neighbors and accessed records the other detectives never found and was able to locate our relative. Great work, Tom! I'd highly recommend this firm.

It is my pleasure to provide a recommendation for the Indiana based Lauth Investigations International. As founder of the Nation's Missing Children Organization, Inc., in 1994 and the National Center for Missing Adults in 2000, I served as CEO for nearly 17 years. During that time the agency utilized the services of Lauth Investigations as an adviser on missing person cases and also referred hundreds of families of missing persons who requested investigative services. The feedback from families of missing persons who retained services or received pro bono services from Lauth Investigations was always consistently positive. The staff at Lauth Investigations always treated our clients with utmost compassion, professionalism and respect. Lauth Investigations also worked cooperatively and professionally with law enforcement agencies throughout the country on behalf of our clients who also provided very positive feedback. In addition, as former CEO and media liaison for National Center for Missing Adults, Lauth Investigations owner, Thomas Lauth, and I frequently worked with national news media and helped generate extensive news coverage for the families of missing persons we represented throughout the nation. After working nearly two decades with Lauth Investigations, I highly recommend utilizing their services!

I needed evidence for a court case and my first private investigator could not find much to help me out. I found this Indianapolis Private Investigator firm and talked to Thomas Lauth. In 24 hours he had already had a file built for me. I am impressed. Thanks Tom!

I would highly recommend the services of Lauth Investigations - I was in need of the services of an investigator for a custody dispute. A coworker who had previously used Lauth Investigations International on a missing person case recommended that I call the Indianapolis Private Investigator and owner of Lauth Investigations International, Thomas Lauth. After speaking with Tom the first time – a sense of relief came over me, he immediately made me feel comfortable with my decision to hire an investigator and he answered all my questions and kept me informed throughout the entire investigative process. Tom is an educated and experienced PI with over 20 years of experience. He and his staff were very kind and took the time to listen to all of my needs and concerns. During a very difficult time I was treated with understanding, compassion, and respect. He made very smart and reasonable suggestions about how to best proceed with my individual case. And was quick to proceed almost as an advocate for my child - Tom was able to learn and confirm my suspicions and get me all the information and proof that I needed to take to the Judge. I am pleased to report that based on the outcome of this investigation – I was able to win my court case and protect my child. Thank you, Tom. I appreciate all that you did for us!!

We used Lauth Investigations on a divorce case for our law firm. They were very professional and we received immediate attention to our case. They were always discrete and we got our reports in a timely manner. I would recommend Lauth Investigations to anyone needing to hire a private investigator.

-Kara Conerty

Lauth Investigations has handled all of our background investigations and internal investigations for over ten years. Before using Lauth, we had repeatedly experienced troubles with new hires until we engaged this firm to help us root out applicants with a pattern of issues in the past or who have lied on their resumes regarding their qualifications. Our firm enters other businesses for service and the last thing we want to do is to send them an unsavory character. Our employee retention rates increased 50% after using Lauth because we were hiring the RIGHT people. I would highly recommend Lauth Investigations. Their pricing is very reasonable and they are pleasant to work with. When I need something, they always hop to and get it done.

-Cal H

Lauth Investigations was amazing, caring, professional and came within hours of our call ready to hit the ground running. They researched, followed and put pressure on all involved parties to get our loved one found quickly and safely. There is no way we could have done it without them and thank them from the bottom of our hearts!

-Lisa Hall

Wow! We used this firm to help locate a missing semi. We had no idea where the truck may be, and very little information surrounding the man that was supposedly in the truck. Within four days these guys had him narrowed down to one small town in Georgia. They did a wonderful job and are also very well at interacting with their customers on a personal level. I would highly recommend and if we need similar services in the future, there is no doubt that Lauth Investigations will be the ones that we call!

-Shawn Stinson

Lauth Investigations International, Inc. has been very helpful in many of our cases at Alerding Castor Hewitt LLP. Lauth has assisted us by performing asset searches, skip traces, and service of process. Lauth also referred a case to us in which we worked to domesticate a judgment in the State of Indiana for a substantial amount. His results are accurate and delivered in a timely manner. We would recommend his services again and again.

I had my ipad stolen while I was in Indianapolis. I contacted Thomas Lauth and his team was able to recover it. He was very professional. I would highly recommend his company should the need arise.

-Michele Horton

Lauth Investigations was very thorough in their investigation and was able to discover the information we needed for a pending lawsuit. However, the greatest attribute is their customer support and service. Lauth was constantly updating us on their progress and asking about our needs in order to best accommodate.

Client Thank You Letters

To Thomas Lauth:”Recently my son was missing and we had nowhere to turn until we found you. Our son had taken off for work and never got there. No one knew where he was and I called the Missing Children’s Hotline. You don’t know what you gave back to us. My son means the world to me and getting him back made my world complete again.”

Donna, the mother of Seth

To Thomas Lauth:”I hired three other private investigators in the city of Indianapolis and they did not produce any results for me. Once you got involved in my case, I breathed a big sigh of relief knowing that somebody cared. In my opinion, I think you are the hardest working P.I. in the city of Indianapolis and you are an expert in the field.”

Mari, the mother of Adam

To Thomas Lauth:”A few weeks ago my 17-year old daughter was missing. I cannot describe in words just how awful I felt during this horrible ordeal. I hired Tom to find my daughter, Alicia. I could sense that he had a deep caring for children. Now my daughter is safe. Tom called a few weeks after she was found to see how we were doing.”
