The Forensic Revolution: How Science is Rewriting Canadian Cold Cases

Welcome to Episode One of this special series "Science Solves: Cracking Canada's Cold Cases".

For decades, many of Canada’s most haunting unsolved cases remained frozen in time, not because investigators didn’t care, but because science simply wasn’t ready.

In this premiere, we break down DNA in a clear, accessible way and explain why early testing couldn’t identify suspects who weren’t already in the system. We look at how investigative genetic genealogy — IGG — opened the door to solving cases once considered impossible, from long‑buried homicides to unidentified remains.

You’ll learn how modern DNA technology works, why it matters, and how it’s giving families the truth they’ve waited decades to hear. This episode sets the foundation for the stories ahead — stories where science doesn’t just solve crimes, but rewrites history.
