Dr. Della Wilkinson, a retired research scientist from the Royal Canadian Mounted Police (RCMP), has transformed crime scene investigations. Her unique approach to forensic science has significantly impacted how evidence is analyzed and recovered in challenging conditions.
Innovative Approaches to Forensic Science
Wilkinson dedicated her career to solving complex cases where evidence was scarce. She focused on how fingerprints, DNA, and other traces perform in real-world environments—exposed to fire, chemicals, and extreme temperatures. Her work has helped recover critical evidence often overlooked in traditional investigations.
A Pioneer in Applied Forensics
In December 2025, she was appointed a Member of the Order of Canada for her contributions. Her groundbreaking work is reflected in various high-profile investigations, including the ongoing crisis of Indigenous women disappearing along British Columbia’s Highway of Tears.
During her time, Wilkinson collaborated with the National Research Council (NRC) of Canada. Together, they explored the use of hyperspectral imaging to detect disturbed soil, which could indicate potential burial sites. This innovative technology, however, needed miniaturization for practical field use.
Strengthening Investigative Techniques
Wilkinson was instrumental in the transition from paper to polymer banknotes in Canada. This switch created challenges in fingerprint analysis, requiring new techniques. She worked with an international group of fingerprint experts, who shared best practices and helped adapt established methods to the new materials.
Crisis Response Research
Her investigations expanded into high-risk conditions, notably after the anthrax letters incident in 2001. She identified how hazardous substances influence the behavior of fingerprints and DNA, leading to improved evidence collection methods. This research proved crucial, as standard techniques often failed in contaminated environments.
Enhancing Court Standards
Wilkinson also played a vital role in developing national and international standards for fingerprint evidence in court. In 2010, she co-founded the Canadian Friction Ridge Working Group, which unites experts to establish reliable standards for the justice system.
Her expertise was pivotal during the R. v. Bornyk case in 2017, the first significant court challenge regarding fingerprint evidence in Canada. The court ultimately validated the reliability of fingerprint identification, thanks in part to her testimony and research.
Collaboration and Mentorship
Throughout her career, Wilkinson emphasized collaboration. She fostered partnerships between academic institutions and law enforcement to translate scientific research into practical applications. Her mentoring has shaped many current forensic scientists, equipping them to tackle real-world challenges.
Leaving a Lasting Legacy
Dr. Wilkinson’s influence extends beyond her scientific achievements. Colleagues describe her as humble and dedicated to aiding victims. She encouraged upcoming scientists to seek knowledge and solutions creatively, stating that success relies on collaborative efforts across various fields.
Her recent appointment reflects a commitment to advancing forensic science in service of justice and victim advocacy. Dr. Wilkinson’s legacy is framed by her tireless pursuit to ensure that science remains a powerful tool for investigators and the families they serve.
