A Century of Solving Crimes
The Revolutionary Evolution of Forensic Science in Quebec
Where Science Meets Justice
On a freezing January morning in 1922, a body was discovered near a municipal equipment shed in Quebec. This ordinary crime scene would become the setting for an extraordinary North American first—the use of ballistics evidence in a murder trial. At the center of this forensic revolution was Dr. Wilfrid Derome, a pioneering scientist whose work established Quebec as the birthplace of modern forensic science on the continent.
From the creation of North America's first governmental forensic laboratory in Montreal in 1914 to today's cutting-edge DNA analysis, Quebec's forensic journey represents a century of scientific innovation that has transformed how crimes are investigated and solved. This article traces the remarkable evolution of forensic techniques that have made the Laboratoire de sciences judiciaires et de médecine légale (LSJML) a world-class institution where justice and science converge 1 .
The Derome Legacy: Building North America's First Forensic Laboratory
Dr. Wilfrid Derome's vision for scientific investigation of crimes began taking shape after his studies in Paris at one of only two scientific institutions in the world that specialized in solving crimes through science and medicine. Under the mentorship of famous French doctors of forensic medicine including Victor Balthazard and Alphonse Bertillon, Derome returned to Montreal in 1910 with a diploma in legal medicine and expertise in emerging fields such as ballistics analysis, criminal psychology, and fingerprint identification .
Did You Know?
Derome's original laboratory was situated above the city morgue, with terms specifying that employees avoid using the main entrance to avoid disturbing clients of the landlord's funeral parlor.
Scientific First
In 1922, Derome's lab performed the first blood alcohol quantification in North America, pioneering toxicological analysis for legal purposes.
With unwavering determination and support from the legal and medical community, Derome lobbied the Quebec government for an institution dedicated to forensic science. His efforts culminated in 1914 with the establishment of the Laboratoire de recherches médico-légales—the first forensic laboratory in North America. The original location was modest, situated above the city morgue at 179 Craig Street East .
The Ballistics Revolution: Solving Crimes Through Bullet Analysis
The 1922 murder case of Raoul Delorme would become Derome's most famous early application of forensic ballistics. The suspect was Reverend Adélard Delorme, the victim's half-brother and a priest—making the case politically sensitive and highly publicized .
"Derome methodically rolled each bullet on carbon paper, then rolled the carbon-covered bullets onto a blank page. The striations left on the bullets from the pistols' barrels created distinct patterns on the paper."
In his cramped Montreal laboratory, Derome conducted meticulous experiments using two Bayard pistols (a Browning and a Mauser) and the .25-calibre bullets that detective Georges Farah-Lajoie had fired from them. After photographing the bullets' trails and enlarging the images for closer examination, Derome found the match he had been expecting: the bullets retrieved from the victim's skull matched those fired from the priest's gun .
At trial, Derome constructed large models to demonstrate to the jury how projectiles fire and are uniquely marked by their passage through a firearm barrel. In a grisly show-and-tell exercise, the jury inspected and passed around the victim's skull to see the precise entry points of the bullets and where Derome had extracted the slugs. Though the priest was ultimately acquitted after four trials, Derome's ballistics evidence set a precedent for the use of forensic firearms examination in North American courts .
Evolution of Forensic Techniques in Quebec (1914-2020s)
| Time Period | Key Technologies Introduced | Notable Cases |
|---|---|---|
| 1914-1920s | Blood alcohol quantification, early ballistics analysis, crime scene preservation protocols | The Delorme case (1922), Hochelaga Bank robbery (1924) |
| 1930s-1950s | Serology (blood typing), toxicology screening, document analysis | - |
| 1960s-1980s | Chromatography techniques, fingerprint classification systems | - |
| 1990s-2010s | DNA analysis, digital forensics, advanced chemical analysis | - |
| 2020s | Next-generation sequencing, artificial intelligence applications | - |
Beyond Ballistics: Expanding the Forensic Toolkit
While Derome's work in ballistics garnered significant attention, his vision for forensic science was remarkably comprehensive. Understanding that solving crimes required multiple scientific approaches, he systematically expanded the laboratory's capabilities to include various disciplines 1 .
DNA Analysis
Genetic fingerprinting revolutionized identification techniques with unprecedented accuracy.
Digital Forensics
Recovering and analyzing data from computers, smartphones, and electronic devices.
Chemical Analysis
Identifying minute quantities of substances with advanced instrumentation.
In 1928, Derome wrote a twenty-eight-page booklet titled "Le Lieu du crime" (The Crime Scene), summarizing directives he had given to Quebec police forces over the years. This publication outlined proper crime scene management, stipulating that the first duty of police was to neither touch nor move anything, and their second job was to summon experts without delay .
A Closer Look: Derome's Pioneering Ballistics Experiment
To appreciate the significance of Quebec's forensic evolution, let's examine Derome's groundbreaking 1922 ballistics experiment in greater detail. This investigation established protocols that would become standard practice in firearms examination throughout North America.
Methodology: Step-by-Step Scientific Rigor
Evidence Collection
Detective Georges Farah-Lajoie recovered the victim's body and secured the crime scene, then collected firearms suspected to be involved in the crime.
Control Samples
The detective fired bullets from each suspected firearm into a recovery medium to create comparison specimens.
Bullet Recovery
Derome carefully extracted the bullets from the victim's skull during autopsy, taking care not to damage the projectiles' surfaces.
Pattern Transfer
Derome rolled each bullet on carbon paper to coat its surface, then rolled the carbon-covered bullets onto blank paper to transfer the striation patterns.
Documentation & Comparison
The resulting patterns were photographed, enlarged, and systematically compared with control samples.
Results and Analysis: Establishing Scientific Certainty
Derome's analysis revealed that the striation patterns on the bullets recovered from the victim matched those fired from Reverend Delorme's Browning pistol. These markings—unique imperfections created inside firearm barrels during manufacturing—function like ballistic fingerprints, allowing definitive identification of which firearm fired a particular bullet .

The Scientist's Toolkit: Essential Forensic Reagents and Materials
Forensic science relies on specialized materials and reagents to analyze evidence effectively. Here are some key components of the forensic toolkit, both historical and contemporary:
Comparison Microscopes
Essential for firearms examination, these specially designed microscopes allow side-by-side comparison of evidence bullets and toolmarks.
Presumptive Test Reagents
Chemical solutions that indicate the possible presence of substances like blood (phenolphthalein), semen (acid phosphatase), or drugs (Marquis reagent).
DNA Extraction Kits
Commercial kits containing reagents and protocols for isolating DNA from various biological samples.
Alternate Light Sources (ALS)
Used to detect latent fingerprints, bodily fluids, and other evidence not visible under normal lighting conditions.
Carbon Paper
Used in Derome's early ballistics experiments to transfer striation patterns from bullets to paper for documentation and analysis.
Gunshot Residue Collection Kits
Contain materials for sampling and preserving particles characteristic of firearm discharge.
