Carter Vigh

At the time, wildfires were raging throughout parts of British Columbia and so Amber checked the air quality index on a weather app that morning to make sure it was safe for Carter — who had asthma — to play outside.

British Columbia's coroner has issued a public safety bulletin about wildfire smoke, saying the death of a nine-year-old boy had been "confirmed by his parents" to have been related to a medical condition aggravated by the smoke.
