David Knoerlein, CEP
"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.
