Scott De Broux has an Associate of Science Degree, a Bachelor of Business Administration in Marketing with a minor in Economics, over 13 years of full-time law enforcement experience, and 14 years of military experience with the Wisconsin Army National Guard. Prior to law enforcement, he was an amateur photographer for 10 years, giving him over 23 years of photography experience.

Scott started his law enforcement career with the Antigo Wisconsin Police Department, taking an immediate interest in (and specialized training in) crime scene processing and police photography. While there, Scott qualified as a Field Training Officer and wrote the field training program. He transferred to the Appleton Wisconsin Police Department in 1999 and qualified as a Patrol Evidence Technician in 2000. In 2004, he was appointed to the Identification Section (currently assigned as a Senior Sergeant). Scott’s duties include crime scene investigation, latent fingerprint processing, crime scene and forensic photography, forensic video analysis, management of the department’s evidence and property control function, and others. He also served five years on the SWAT Team. In addition, Scott teaches in the Recruit Academy, Forensic Science Applications (classroom and online) Academics, and specialized training related to CSI work (especially photography).

Scott has 1800 hours of specialized training, of which nearly 1190 is related to crime scene investigation and forensic analysis of evidence. With a specialization in police and forensic photography and forensic video analysis, Scott is frequently called upon by other agencies in the state to assist in these areas. He also specializes in the use of alternate light sources for the documentation of injuries, especially in domestic abuse strangulation cases and child abuse.

Scott is a member of the International Association for Identification (IAI), Wisconsin Association for Identification (WAI), and Law Enforcement Emergency Services Video Association (LEVA). He has recently participated in the Evidence Photographers International Council (EPIC) Certification Committee, writing standards and test items for an international certification program for forensic and police photographers.

Published in Evidence Technology Magazine and Government Video Magazine, Scott also coauthored a research paper on the use of infrared photography in the criminal justice system. And along with being a Certified Forensic Video Technician through LEVA and a Certified Evidence Photographer through EPIC, Scott received a 2006 Outagamie County Best Badge Award for trial preparation and testimony in two homicide cases that resulted in convictions.

David Knoerlein
"Digital-Dave" Knoerlein is a Certified Evidence Photographer and the President of Forensic Digital Imaging, Inc., a consulting firm that provides forensic imaging services to law enforcement, corporations, and the legal community. As a devoted crusader for the use of digital imaging technologies in law enforcement, Knoerlein is currently researching the issues surrounding the long-term storage and archiving of digitally captured images of evidential value.  

Beginning as a forensic film photographer in 1984, Knoerlein quickly recognized the benefits of digital imaging. He was introduced to forensic digital imaging during his time at the Baltimore County Police Department, becoming a leading authority on the topic. Knoerlein developed and implemented the (SOP) Standard Operational Procedures for the use of digital imaging technologies for law enforcement at Baltimore County, which were later shared by agencies across the nation.

As a forensic analyst for the Broward County Sheriff’s Office, Knoerlein achieved another milestone with the State of Florida vs. Victor Reyes murder case. Knoerlein qualified and testified as an expert in digital imaging, where he dispelled the misgivings of digital imaging enhancements as voodoo science. The Reyes case is one of only a few cases in the United States to successfully pass a Frye hearing that challenged the use of digital imaging enhancement technologies. This case gained national media attention when featured on a 60 Minutes episode entitled “The Hidden Clue.”

Recognized as one of the leaders in forensic digital imaging, Knoerlein was sub-contracted by MoreHits (now Foray Technologies) to provide training to police agencies across the country on their image management software. The Miami Dade Metropolitan Police Institute also recruited him to provide classes on digital enhancement.

From 2003 to 2007, Knoerlein was contracted by the Justice Department as the Imaging Systems Manager for the Crime Scene Investigation unit led by the Army Corp of Engineers to design and manage an imaging system to document the mass grave exhumations in Iraq. This system not only categorized and stored 90,000 images; it also encompassed detailed descriptions and cataloguing to allow for query and analysis of the evidence collected by archeologists, document examiners, pathologists, prosecutors, and all team members. Without question, it was the strictly adhered to Standard Operating Procedures—developed by Knoerlein—that legitimized this secure digital imaging system to withstand any scrutiny in World Court. The evidentiary images gathered and maintained by Knoerlein’s system played a major role in the prosecution of Saddam Hussein and others for genocide in Iraq. This was no small feat given the hostile work environment and geographic obstacles the team faced on a daily basis.

Today, you can expect to find Knoerlein speaking at law enforcement conferences across the country. In addition, he has recently been featured in Evidence Technology magazine’s May-June and Sept.-Oct. 2008 issues.

Thomas Doggett
Thomas Doggett has associate degrees in Photography Technology and Criminal Justice, a bachelor’s degree in Business Management, and over 20 years of full-time law enforcement experience (including working as a Crime Scene Investigator for the past 17 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.

Hs 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), International Law Enforcement Educators and Trainers Association (ILEETA) and Professional Photographers of America (PPA). He also serves as the vendor representative for the Illinois Division International Association of Identification’s annual conference.
