The framing of the story should be the story. 

One frame is that a young man seemed to come unhinged around the age of 20, committed multiple crimes, served several years in prison, where his condition worsened, attached himself to hateful ideas, apparently aimed at multiple targets, ranted about all sorts of things, and ended up verbally abusing and threatening two young women while ranting about Muslims, and stabbed two men to death when they tried to intervene.

Another frame, in one of the other AP stories, begins by placing the event at the start of Ramadan and in the context of ideological anti-Muslim hate. Here the frame is also white supremacism and racism in Oregon in general, and the target is a broad one, with mentions of lots of groups. 

It's important to weight the relevance of the two frames in rightly explaining the event.
