Teen murders classmate and takes a selfie with the body (and sends it over snapchat)

This is the article: http://www.huffingtonpost.com/2015/02/08/_n_6640376.html

The summary of the article is basically that this one teenager shot his classmate in the face and then took a selfie with the dead body and then proceeded to send this selfie to a bunch of his friends via snapchat. This is appalling to me. This sixteen year old kid shot someone in the face and felt apparently felt no remorse since he took a selfie with the dead body. Now, what I found surprising was what most of the media didn't do. While the first article I stumbled upon on facebook about this topic was very focused on the race aspect of the crime, almost all of the other reports have been very racially ambiguous. This was a black on white crime and with all of the discussions we've been having about Ferguson, I assumed race was going to be a bigger story than it was, which I was both happy and confused about. I'm happy about the fact that people are looking past skin color, but I'm also confused as to why that is. I feel like if this were a white on black crime, it would be all over the news due to Ferguson, the "I can't breathe" controversy, and the Trayvon Martin case. Then, it made me realize that people are more outraged about the fact that the people of authority are white, and they're the ones who are attacking allegedly innocent African Americans.
Although police brutality is definitely an issue (even despite race), why aren't people talking about the teenagers who have been shooting up schools and their classmates? Yes, there has been significant media coverage over a few school shootings over the years like the Sandy Hook Elementary tragedy, but overall, the issue doesn't see much light.

For something that occurs so often, why does nobody really know about them? And why are teenagers starting to use social media outlets (namely, Snapchat) to showcase their crimes? Are they motivated by social media to post things with such intense shock value? There was even a case recently where a student set a sleeping girl on fire just so he could post it on his snapchat story. It seems as though more and more people are crossing boundaries for the sake of social media, and it's something that was certainly not a problem 10 years ago, so we are going to have to start finding new ways to prevent this violence that people are starting to view as a form of entertainment.
