Had a great experience with Bucksell Group. Very professional team. Took time to advise me on my next steps. Thank you!

My daughter was missing. She is an adult. I knew she was in NE and that she frequented a certain neighborhood. Steve from Capitol Inquiry had two investigators in the neighborhood within two hours. Before I evened signed a contract. They found her that evening. She is now getting the care she needed. What else can I say!

Our Law firm has used Capitol Inquiry for years. When I needed a PI personally our admin recommended them. The resolved a complicated real estate dispute involving falsified deeds and a fake company.
