Actually the Salt Lake Tribune is reporting that he attended the Al-Noor mosque on 700 East Street every Friday. That raises at least the possibility that this kid's mahometan beliefs played a part in the attack.
Bosnian Muslims are not associated with the jihadist crap
Really? Then why has Al Qaeda had terror cells operating in the middle of Bosnia since at least the early 90's? http://www.amazon.com/exec/obidos/tg/detail/-/1859738079/ref=ase_robertspencer-20/103-1603172-8127010?v=glance&s=books
All the evidence points to this being just a messed up kid, possibly due to his early childhood in a violence-infested war zone and growing up with parents who were also traumatized by that experience. He's probably been a cultural misfit ever since he arrived in Utah, due to the foreignness of American culture and the close-knit Mormon-dominated community in Utah. Quite possibly his family discouraged him from getting involved in the LDS Church, due to their religious heritage (probably more important than theological convictions in the case of Bosnian Muslims), contributing to his social alienation
So in other words, it's everybody's fault but his own? It's society's fault for "alienating" him and for the traumas of his childhood? Sorry, but I'm going to have to pass on that one. The kid was a nut, and a very real possibility exists that his nutty religion had something to do with this. In fact, barring evidence suggesting otherwise and knowing the track record of his religion, its relation to this attack should be considered the most likely of the possible motives given at this point barring evidence pointing elsewhere.
I predict the next 9/11-like attack on American soil will be committed by blue-eyed Bosnians. People expect terrorists to always be Arab.
