Expert Witness Services

Our Expert Witness services can help you get the outcome you deserve.

Searching for information is one thing. Substantiating the evidence and having the ability to competently testify to it in a court of law is another world all together. Many of our clients’ cases require our appearance in court to testify to our findings. As a licensed private investigator, we can provide evidence, in addition to expert testimony, that will help your case.

Linked Investigations provides Expert Witness testimony for Local, State and Federal cases, in both civil and criminal courts.

I have used Linked Investigations multiple times. First, it was for reasons of a personal nature. Then I began using Mike's services for my business as well, including background checks and surveillance services.

What I like most about Mike is that he is genuine, takes time to get to know the clients and their needs, and goes above the call of duty to answer questions. He has provided solutions I hadn't thought of before, which is a major bonus as a small business owner. I highly recommend Mike and the his Linked Investigations investigators for both private and corporate investigation.

I have referred many a friend and colleague his way.

I came to a point where in needed a PI for a case I was involved in. I'm glad when a friend recommended me to this place. I was a mess when I sat down to talk about my case. He was very thoughtful and genuinely cared about what I was going threw. He took the time to answer all my questions and walked me through everything step by step. I felt comfortable and safe talking with him. I would definitely recommend going here!

Mike has helped me on several occasions in the last two years for surveillance and background checks on men in my life who were potentially not good for me to be in a relationship with.

Mike has helped me on several occasions in the last two years for surveillance and background checks on men in my life who were potentially not good for me to be in a relationship with. He has far exceeded my expectations every time. He is incredibly perceptive, knowledgeable and highly skilled at what he does. Each time I called him for service, he first helped me to figure out what my goals were so I don't end up wasting my time or money in areas that will not help me gain the information or the clarity I needed. He genuinely cared about my situation and he took the time to explain all aspects of what I can expect in the process. After working with him, I will not even consider working with anyone else.

I called several investigators to ask for help finding the owner of a hit and run vehicle. No one seemed to offer any real help until I talked to Mike. He told me exactly what to tell my insurance company and helped me understand my rights in the situation. Everything he told me was true…and the insurance company resolved the situation! The incredible part…he didn't charge me and he wouldn't even take payment when I offered! I will definitely use his services if needed again, and I want to be sure to pay whatever his efforts are worth!

I recently called Linked Investigators to try to find the owner of an LLC. I sent him all the info I had. A day later he emailed me to call him. We talked, he gave me his assessment of who was who and what was what, gave me some great advice on proceeding or not AND he did not charge me. Today I got a 77 page report!

I never thought I would need an investigator but this situation was gnawing at me and I had to get an answer.
