There is so much that is unfortunate about this. First off, another person dead because of guns. Second, there is so much news and uproar because she was a young white woman. This is undeniable. Third, in looking for statistics on stray bullet incidences, I found that there is no official tracking in the US.
I found a study of 2008 stray bullet incidents, including deaths from combining news reports. In the year, they found 284 of 501 unique reports of different incidences that met criteria injuring 317 ppl (almost one a day). Of these, about 20% died, and most injured were at home, not aware of any gun violence. Suffice to say, each statistic is a person just like her, and their deaths are all needless tragedies brought on by gun culture.
