The Codiac Regional RCMP has successfully identified an individual whose remains were discovered in the Moncton area nearly 20 years ago, bringing long-awaited answers and closure to the person’s family.

In 2007, the Codiac Regional RCMP began an investigation after an adult male was found deceased in the Moncton area. At the time, investigators determined that no foul play was involved. Despite extensive efforts over the years, the individual’s identity remained unknown.

Investigators pursued numerous avenues to identify the deceased, including releasing modified images to the public, working with the RCMP’s National Centre for Missing Persons and Unidentified Remains (NCMPUR), collaborating with INTERPOL, and comparing DNA and fingerprint records with databases in Canada and internationally.

In July 2025, the NCMPUR assisted the Codiac Regional RCMP through the use of Forensic Investigative Genetic Genealogy (FIGG), an emerging investigative technique that combines DNA analysis, genealogical research, and traditional police work to help identify unknown individuals. The process is conducted in accordance with strict legal, privacy, and ethical standards.

With assistance from the New Brunswick Coroner’s Office, the NCMPUR, and the Toronto Police Service, investigators were able to positively identify the individual as William Dean “Billy” Mackay, within a year of applying this investigative approach. The individual’s family has since been notified.

"For more than twenty years we wondered what had happened to our brother Billy. Thanks to the impressive work and excellent cooperation among the team of police, coroner's office, and DNA specialists, we are grateful to finally have the answer,” says Linda Mackay, sister of the deceased.

“This identification brings closure to a family who spent many years without answers about their loved one,” says S/Sgt. Sylvette Hebert of the Codiac Regional RCMP. “We are grateful to our policing and investigative partners whose collaboration, dedication, and expertise helped make this possible.”

The successful resolution of this case highlights how advances in investigative techniques, combined with strong partnerships across jurisdictions, can help provide answers in long-standing investigations and support families seeking closure.

The RCMP continues to explore the use of emerging technologies and investigative methods, including FIGG, in appropriate cases involving unidentified human remains.
