Rahul Ranwa drowned around 3 p.m. last Thursday at the popular beach near UBC. The international student was studying business at Vancouver Community College.

Surveillance video from a residence across from the home at 7340 196 Street captured the thunderous blast which jolted the Willowbrook neighbourhood around 10:40 a.m.

Will Arnold says he and other business owners are frequently forced to extinguish warming fires lit by unhoused people in the area.
