The FBI investigated him twice, actually, and neither revealed enough information or a strong-enough tie to warrant larger interest. It's not their fault, really; It's not as if people have hidden "I AM A TERRORIST" somewhere in their emails or personal life.
The weapons were purchased legally. The worst thing he'd done prior to this was beat his wife, express intolerance for gay people and make some questionable comments around co-workers about suicide bombers. If that's supposed to be enough to hassle someone for being a potential terrorist, well, a huge portion of the country meets two out of three of those qualifications.
This is a terrible tragedy, and I am disheartened that it's happened.
