(Fox News) Fort Hood gunman Ivan Lopez may have had angry words with fellow soldiers before opening fire on the military base and killing three, wounding 16 and then turning the gun on himself, an Army official said Thursday.
Lopez, an Army specialist from Puerto Rico who had been treated for mental problems, was stopped when a Military Police officer confronted him, her gun drawn. Otherwise, the massacre could've been far worse, said Army Lt. Gen. Mark Milley, who was unable to ascribe a motive to the shooting.
"We're trying to figure out what the trigger event was," Milley told reporters, saying investigators are working to determine whether the shooting was pre-meditated.
