I have read the article several times and read the articles in the links that were provided by Magister Phineas, and nowhere in the article is any supported evidence of this scumbag claiming to be a Satanist. They quoted him saying that he wasn't sure if there was a god or not but this isn't even close to admitting to being a Satanist. Once again the media has taken a story and sensationalized it to suit their own needs and blow things out of proportion.
If I'm wrong about the article not giving any real evidence, I'd appreciate if someone would point out where it says this. I may have missed it somewhere amongst the bullshit.

I had the same thought. Here's the extent of it, from what I can can see: "The teen gunman who killed eight people and himself in a mall this month once told social workers he was satanic and acknowledged that he often acted before thinking of the consequences, according to newly released court records." No direct quote, kind of a "take our word for it" reference.
But it wouldn't surprise me at all if the kid did tell social workers he was "satanic". Apparently he came from some kind of Christian background, which he'd become disillousioned about/felt at odds with, and it would be pretty common for a person to label such adversarial/conflicted feelings as "satanic". Too bad he didn't get ahold of the Satanic Bible before going on a pointlessly destructive rampage(I'm almost certain he didn't, as his actions were self-destructive and obviously lacking in insight regarding his philosophical/emotional crisis).
I really despise this kind of media coverage which points to "Satan", or the pot(cause you know those stoners are always taking up arms against mall-shoppers!), or maybe a video game or band as a likely catalyst for this sort of despicable behavior. Confusing symptoms with causes. Of anything I read in these identical articles, the biggest "red flag" for me was the quote by the father who was leaving him in God's hands. Perhaps the kid's welfare had been left in the hands of some imaginary caretaker far too much already...? But, of course, that was a "good" intention on the part of his father. Let's not delve too much into any root causes, when we have convenient scapegoats!
In any case, it's a sad situation when one goes so far astray...but I also echo the sentiment that it was best he offed himself in the process...too bad he randomly took some others with him in his ultimate self-destruction. I really hate it when a person can't get the nerve to kill themselves until they've done something so horrible that they can't bear to live with the consequences(as in the classic case of the guy who kills his family before pulling the trigger on himself). F-ing cowards.
