Thomas Doggett, CEP, CCSI
Thomas Doggett has associate degrees in Photography Technology and Criminal Justice, a bachelor's degree in Business Management, and over 21 years of full-time law enforcement experience (including working as a Crime Scene Investigator for the past 18 years). In addition, he is a Certified Evidence Photographer (CEP) and an IAI Certified Crime Scene Investigator.

Thomas' crime scene investigation and photography experience began in 1993 while working full time as a Deputy Coroner/Death Investigator for the DuPage County (Illinois) Coroner's Office. When he transferred to the Batavia Police Department (situated in both DuPage and Kane Counties) in 1997, he continued to work full time as a Police Officer/CSI, where he continues today. Thomas holds ancillary CSI duties with the Kane County Major Crimes Task Force and maintains the Photo Lab for the Batavia Police Department. In fact, he has been teaching crime scene investigation classes at the College of DuPage Suburban Law Enforcement Academy and North East Multi-Regional Training Center since 2007.

His interest and knowledge of photography goes beyond the forensic specialty, beginning in 1985 when he served as an Infantryman in the U.S. Army’s 101st Airborne Division. There, Thomas always had a camera available and took many photographs of the other soldiers in his unit. Actually, when not shooting crime scenes today, Thomas might be found shooting portraits and weddings.

Thomas is a member of many helpful associations, including the International Association of Identification (IAI), Illinois Division International Association of Identification (IDIAI), Evidence Photographers International Council (EPIC), and Professional Photographers of America (PPA).
