About The Instructor

John Fretts retired from the Bureau of Alcohol, Tobacco, Firearms, and Explosives in 2005, after a distinguished thirty-year career with the Department of Justice, Bureau of Alcohol, Tobacco, and Firearms. John began his ATF career as a special agent in the Washington, DC, field division, where he led numerous federal investigations into violations of federal firearms and explosives laws. In 1991, John was promoted to the position of project manager at ATF Headquarters.

In 1994, John transferred to Connecticut with his appointment as supervisor of ATF's Hartford field office. While in Connecticut, John nurtured his technical interests, developing skills as a specialist in computer forensic investigations. He successfully completed the CIS 2000 Program at the Federal Law Enforcement Training Center in Brunswick, Georgia. He was also certified by the International Association of Computer Investigative Specialists as a Certified Forensic Computer Examiner (CFCE) in 2004. Because of his management experience and knowledge of computer investigations, John was named regional supervisor of ATF computer forensic operations for the northeast United States. While with the ATF, John testified in federal court and is qualified to appear as an expert in computer forensics and data recovery.

Upon retirement from federal service, John accepted a position as director of investigations with Security Services of Connecticut (SSC), a regional firm specializing in a full range of investigative services, particularly in computer forensics.

John had oversight of SSC's computer forensic operation and was regularly called upon to lecture on the topic of computer forensics and data recovery as it relates to fraud and computer misuse. In his presentations to corporate clients and at trade shows, John had an uncanny ability to explain the most complex aspects of computer forensics to those with the least understanding of the subject. With his law enforcement background, John was adept at explaining the necessity to respond rapidly to an incident involving fraud or criminal activity involving computers and the need to preserve electronic evidence.

In August of 2007, John resigned from his position with SSC to concentrate his time and skills on computer forensics investigation and education. John is a member of the University of New Haven, criminal justice curriculum, student advisory board. He is a veteran of the United States Army and has a Bachelor’s degree in criminal justice.
