Welcome to HDI Investigation

Welcome to HDI! I wanted to take just a moment and give you some reasons why you should consider giving HDI Investigation an opportunity to meet your firm’s investigative needs:

I have over 23 years of experience as a Federal Bureau of Investigation (FBI) Special Agent. I have brought the same sense of duty, integrity, honor and skill that made me a very successful FBI agent over to HDI Investigation Service. I also have eight years of private investigation experience. In addition I have assembled an outstanding “Team” at HDI and as a team we have over 70 years of extensive investigative experience.

We specialize in criminal defense cases. We have investigated several capital cases. We have also conducted numerous, 1st degree and 2nd degree murder cases as well as kidnapping, carjacking, rape and armed robberies cases. We have worked for a number of notable attorneys such as Grady Jessup, Johneric Emehel, Norman Butler, W. Terry Sherrill, Robert Torbich, Chuck Morgan, Julir Boyer, Ken Snow, Chiege Okwara and many others.

At HDI we believe as Booker T. Washington once said “Excellence is doing a common thing in an uncommon way.”

Thank you for your time and consideration.

“I didn’t grow up wanting to be in the FBI,” said Charles Williams. But a chance encounter with an FBI agent, who was opening up an account at the Albany, N.Y., bank where Williams was assistant branch manager, changed his career path.

After the necessary application and education process, Williams went on to lead an exemplary 24-year FBI career. Williams is hoping to use this experience in his new business, HDI Motivational and Leadership Consultant Group, a motivational speaking company that recently opened in the Lake Park Town Center.

During his years in the FBI, Williams investigated the 1993 World Trade Center bombing and Sept. 11 attacks, practiced foreign counter intelligence in Tanzania and Kenya, and contributed to solving some of New York City’s most violent crimes. One of these investigations included working undercover to find witnesses to testify in the death of Yankel Rosenbaum during much-publicized rioting in Crown Heights, Brooklyn, in 1991. For his actions in that case, Williams received recognition from Attorney General Janet Reno. He also has received more than 13 letters of commendation from the FBI, including several from William Sessions, who served as the director of the FBI ! from 1987 to 1993. In one letter, he commended Williams for his “excellent investigative technique.”

LAKE PARK – The village of Lake Park, home of Charles Williams’s business, HDI Investigations, couldn’t be further from the streets of New York City, where Williams once spent more than two decades as a special agent for the FBI.

When Williams moved to Indian Trail and began his business in the village of about 2,000 people after retiring from the bureau in 2006, it took him a while to make peace with the transition.

“I lived in NYC for 21 years and it was nothing but concrete and streetlights and skyscrapers, so you get used to that fast pace,” Williams said. “It took me a little while to adjust to the slower pace here, the smaller amount of people. After a while, I came to appreciate seeing the cows in the pastures.”
