Guest: Wendy Gillis, crime and policing reporter

Over the past nine weeks, a Canadian courtroom heard disturbing testimonies of how and why 22-year-old Nathaniel Veltman murdered three generations of a Muslim family in 2021. Now guilty for the deaths of Salman Afzaal, his wife Madiha, 15-year-old daughter Yumna and 74-year-old mother Talat, and for the attempted murder of Salman's nine-year-old son, the upcoming sentencing will be a significant litmus test for Canada's anti-terror laws. What is also critical is the need to unravel how a small-town factory worker just out of his teens became a deadly mass murderer. Veltman's descent down the rabbit-hole of far-right extremism has exposed a deadly threat in Canada, as hate is once again on the rise. We retrace the digital footsteps of Veltman's radicalization.
