The most recent story I heard was that the shooter was a disgruntled ex-husband/boyfriend who just got out of prison and hunted down his ex-wife/girlfriend(and apparently some of the coworkers, maybe at random?)
Either way, awful story, especially when it hits close to home, regardless of his motive or history.
Edit: The official story seems to contradict what I heard. Who knows.
