In Killeen, Texas, another mass shooting had some asking, "Again?" The flags flew at half staff as the community began to pick up the pieces.

Also: Secretary of the Army says background checks on the soldier who killed at least three people and wounded 16 before taking his own life showed "no involvement with extremist organizations."

The suspected shooter at the Texas Army post is Ivan Lopez, a Pentagon official tells NPR. Authorities say he was being evaluated for PTSD and treated for depression.
