Experienced Hikers Mauled by Grizzly in Canada's Banff Park Despite Bear Spray

Doug Inglis and Jenny Gusse, experienced campers, were killed by a grizzly while hiking in Banff National Park.
The couple sent a distressing final text to family saying "Bear attack bad" before their deaths.
An empty bear spray canister was found at the scene, indicating attempts to deter the bear failed.
A grizzly bear was located nearby displaying aggressive behavior and euthanized by park authorities.
The mauling deaths have heightened concerns about bear encounters with humans in the park.
