Counterterrorism investigators are trying to figure out why a 24-year-old Kuwait-born man who by many accounts lived a typical life in suburban America attacked two military facilities in a shooting rampage that killed four Marines.

A gunman unleashed a barrage of gunfire at two military facilities Thursday in Chattanooga, killing at least four Marines and wounding a soldier and a police officer, officials said. The suspect also was killed.
