You know, if you get to researching this stuff, you realize it's more common than you think. But anyway, just looking at the 2000s, check out how often a black bear kills, and how often it seems associated with predation of the human by the bear. I have read somewhere else recently that black bears are much less likely to attack to protect their cubs than a Griz is.
There were about 52 recorded deaths due to black bears between 1900 and 2003 and about 50 deaths due to brown bears and about 5 due to polar bears in the same period. The most recent data is the most reliable and complete, but does not necessarily include all of the fatal attacks that have occurred in North America. Prior to recent decades bear attacks were not well documented, particularly those which took place in isolated regions. As a result there were more attacks and fatalities than have been recorded as shown here, particularly in Canada and Alaska.
2005 was a notably bad year for fatal bear attacks in Canada with 5 in the span of only a few months, generating increased media attention on the subject. Wildlife conservation officials issued public warnings in certain areas known to have large bear populations in close proximity to humans.
