Bill’s trailblazing career journey began as a Graphic Designer before he transitioned into policing. His creative skills remained a constant throughout his career, especially when investigating images and video content. In 2012, Bill made history as the TPS’s Image Analyst during the G20 protests. Tasked with unmasking and identifying Black Bloc protestors through digital imagery, he spearheaded Canada’s largest criminal image investigation solely reliant on this cutting-edge approach.

Bill’s impact extended beyond individual cases. As Detective Sergeant in charge of the Intelligence Services Coordinated Cyber Centre (C3) and the Technological Crimes Unit (TCU), he provided leadership and expertise to a team of over 20 cyber investigators and 10 digital forensic analysts. Their work spanned diverse crime types, from homicides to cyber offenses, including frauds, scams, and data breaches. Bill also conducted internal investigations, ensuring professional standards were upheld.

Bill has been championing Child Protection for the majority of his policing career. Bill’s commitment to protecting vulnerable populations is unwavering.

As Canada’s pioneering Victim Identification Officer, he collaborated with the Ontario Victim Identification Team and the Interpol Specialist Workgroup on Crimes against Children as a principal trainer and investigator. His efforts have led to the identification of over 100 children globally.

Bill’s innovations are legendary. He authored the first-ever Production Order to Passport Canada’s Facial Recognition System for a Child Exploitation investigation—a groundbreaking achievement. He also developed methods to successfully scale and enhance fingerprints seen in online photos to allow them to be entered into AFIS (Automated Fingerprint Identification System). A digital first for law enforcement.

External agencies, including the FBI and CSIS, have sought his expertise in complex image investigations. Officers from around the world have travelled to learn from Bill’s techniques. Bill is also a court recognized expert in the area of Image Analysis.
