It could well be that, depends on if it was a tourist or a local. Locals aren't that foolish but they do get complacent about their safety in the wild, because they're always there. What they forget is that it's not like anywhere else and special precautions are necessary every day and night. As a local, we know better than to take an evening stroll through town, there's likely to be a bear roaming around looking for free food left out by tourists.
It could also be that she was out for a jog. There are several high end lodgings in the area so some of the more monied tourists would be on foot out there, nobody else would be that far from town on foot, not with out a vehicle nearby or other people with her. The attack would have been reported if she were with someone... that's the most common possibility in these cases though details have not been released... have to wait for investigation report.
Other possibility is that it was someone who went for a walk and was not thinking about their safety, which is just as likely.
So if it was a jogger, probably had earbuds too, might not have known what was going on until the finally moments under attack. Jogging in bear territory. like as wild as that but even along the road anywhere in the area, is just stupid but also a strong possibility. Seen too many clueless people tempting fate in this way.
It doesn't make sense that she was out there unless she was someone like me who also broke the rules a lot but also was vigilant about my surroundings with or without bear spray on my person. I had a couple close enough calls that I realized I had to be armed with it. Then I became an official presenter on the topic. If I got nailed by a bear in my current life, the papers would be all over how stupid I was to have allowed it to happen, seriously, and I would deserve it.
I am waiting to see what the real story is, this is a little strange but not entirely. If it was some notable individual who is wealthy, there will be more news about it.
