Oct 16, 2021 Report
I needed a private investigator as I was in a very tough position personally. I had hired an investigator back in 2019 with little to know response. Crucial Investigator team of husband and wife is so thorough and whether positive or negative the true and honest results you will know. After reaching out I was contacted within 10 minutes, if not shorter, and had an appointment for the afternoon. From the very onset the professional and caring matter was laid out and I hired immediately at the end of our meeting. Everything that was explained to me was done over and above anything I could have

Crucial Investigations helped surveillance my x-wife to make sure she was following our divorce decree's morality clause. Dan and Frances were very professional. They were able to gps track both my x-wife and her new boyfriend. Detailed videos were provided. Great group to work with. Highly recommend!!

I hired Dan in 2013 due to unfortunate circumstances in my life but if you have to hire a PI, he's your man. His wife, Frances, is also an absolute gem. Dan & Frances treated me with compassion and with the upmost respect when I felt my life was falling apart. They loved and cared for me in a matter of minutes of knowing them, which is exactly what I needed. Dan was very responsive and kept me abreast of his investigation which was thorough and handled in a very timely manner. I certainly cannot say enough positive attributes about these 2 wonderful people, both personally and professionally. I
