Forensic Identification Class Takes Tire Tracking Lab Outside

In November 2025, Forensic Identification Professor Andrea MacLeod guided her students through a tire impression lab that took an unexpected real-world turn. Although the class had a standard tire impression lab planned for the day, one of FSCS’ forensic technicians reported that someone had recently driven over a curb and onto Humber property, causing significant damage and leaving behind large, clear tire tracks.

Recognizing an ideal opportunity for hands-on learning, Professor MacLeod quickly gathered casting materials and led the students outside to examine the scene.

The class discussed the evidence as if it were a real-life scenario, similar to a hit-and-run case. Students examined the impressions left in the mud and were challenged to determine the vehicle’s direction and possible tire type.

The students successfully created a 3D stone casting of the tire impression in the mud for future analysis and training purposes. They were also provided with locally-sourced used tires and were tasked with completing 2D impressions, which they later analyzed, further enriching their learning experience.
