An intriguing fact is that the shooting comes just four months after the Fort Bliss Commanding Officer Maj. Gen. Stephen Twitty announced new security measures. A “code white” was issued over the intercom system indicating an active shooter and ordering people to seek shelter, when the incident occurred. Investigators haven’t said whether the gunman killed himself or was killed by someone else. The motivation of the gunman is not known. The killed doctor’s name wasn’t revealed to the media. The VA said in a statement that it “is deeply saddened by the tragic situation that has occurred in El Paso, and we are actively working with our partners at Fort Bliss to investigate this matter.”
