More than two years after Canada’s worst mass shooting, we’ve finally heard from someone who was there at the start. Lisa Banfield, the shooter’s common-law spouse, spoke last Friday at the inquiry into how the RCMP handled the incident. She provided insight into what happened in April, 2020, and described a chilling portrait of intimate partner violence.

The Globe’s Greg Mercer tells us about what Banfield witnessed, the shooter’s violent history, and why some of the victims’ families walked out during her testimony.
