Mine was a missing person case Mine was a missing person case. It was my son. He had been missing and my daughter-in-law only alerted me 3 or 4 days later. Having been in touch with the Suffolk County Police Department in New York, I realized nothing was getting done because my son was an adult. I searched for a private investigator online and found Darrin Giglio and his company. It was the best result. Darrin and his team ended up finding my son’s body and that of another young victim AND was able to determine who was responsible for this heinous murder. All the evidence was then turned over to local law enforcement. The perpetrators were convicted and sentenced. With Darrin’s team, NOTHING would have been done and I would’ve been left with a missing son all these years and the criminals would’ve still been on the streets! Just a last word: my choosing Darrin and his team, in my opinion, was a Godsend!

Professional, thorough and quick! I can't stress enough how important using an experienced investigation company is. I had a bad experience with another P.I. firm and Darrin and his team immediately started on my case, they provided me daily updates and sent me the reports very quickly. I am very impressed and would definitely use them again if needed. I highly recommend them and am very satisfied. They are truly the best out there.

NAI and Darren Giglio were amazing! Working with NAI was a great experience. I had never used this type of service before and I was nervous about how to proceed. Darren Giglio, my PI, was excellent. He explained everything in great detail and went above and beyond to help me with my complicated situation. I would definitely recommend Darrin and would work with him again in the future!

Great experience This was a surreal experience for me - something I thought I'd never find myself doing. John was so great to work with - he made me feel so comfortable, got me the info I needed quickly and checked in after to see how the situation was resolved. Hoping I never need him again (don't take it personally John!!), but if I do I know where I'm going!

I had struggled for months to track… I had struggled for months to track down a person critical to the research I am conducting for a book. I found North America Investigators online and called their 800 number. Darrin answered and dealt with my query clearly and efficiently. I received the person's contact details within a couple of days. I was very impressed!
