Sorry guys, I couldn't resist. This guy had the awful luck of surprising a sow with cubs, that's lethal every time.
And, it sounds like he did all the wrong things. Running away from a bear capable of 35 MPH is not a race you're gonna win. His wife, after he was mauled, laid down behind a bush, played dead and the sow picked her up a spit her out. She'll be fine, widowed, but alive.
Arm yourselves, it's legal these days...6 rounds from a .44 would have done some serious deterrence. Shit, I carry a sidearm to take out the trash here in the northeast. We have bear, coyote, dogs and neighbors...
