The Constitution of The United States provides people charged with a crime the opportunity to be heard in their quest for justice. We learn of innocent people accused, charged and finally convicted of crimes they did not commit. We rely on an inconsistent criminal justice system to prove their innocence. We learn the hard way that we were wrong. By the Police or prosecutorial misconduct. The Civil rights of many American Citizens are frequently violated.

Milton Florenz, Attorney

My criminal defense practice requires high intensity and thorough investigations. I have had the privelege in hiriing Mr. Acosta in high profile criminal defense cases and he was able to use his analytical and investigative skills in obtaining great results. Mr. Acosta and I also traveled to Colombia, South America, to interview a witness in a homicide case and his experience and understanding of the Colombian culture was crucial in the defense of my client. 

Glenn Herman, Attorney

I highly recommend William Acosta as a priviate investigator. He is highly reliable and very professional. He speaks several languages and travels internationally as well as locally. My office uses him for all our investigation work.

William Acosta


Has worked for me on numerous occasions during the past 20 years, serving as an international investigator and police instructor in South America. He is extraordinarily gifted in all aspects of covert operations and investigations. -Michael Levine, Trial Consultant/Expert Witness
