At the point of the attack, the two suspects apparently drove up and opened fire upon an unarmed security guard who was accompanied by a 60-year-old Garland police officer. The unarmed guard was struck the volley of gunfire. The veteran Garland officer then drew his duty-issue Glock pistol and opened fire on the suspects.
The officer killed one terrorist and wounded the other in his initial volley of return fire. Witnesses claim there was a brief pause, and then the officer fire two more shots to kill the still-moving terrorist as he appears to be reaching for a backpack. The entire event lasted 15 seconds, with heavily-armed Garland SWAT converging on the scene immediately afterward.
We’re not going to mention any more about the officer who took out these terrorists, only that to give an idea of his approximate position in relation to the terrorists as he engaged them.
