ABC19980324.1830.0103 NEWS CAPTION Good evening. They were so young, which only enhances the shock -- the shooter, that is, were so young. The boys with the guns were 11 and 13, we are told. They killed four people and wounded a dozen. All over the country today people wondered why has it happened again, and where might it happen next? First, with the details, ABC's Morton Dean. the deadly shooting spree appeared to have been well-planned, an ambush -- kids shooting kids. The authorities so far have developed this deadly scenario. One student, perhaps an accomplice of the killers, pulling a fire alarm in the school. The students, sixth, seventh graders filing outside in orderly fashion. We heard the fire alarm. So we all started coming out. We heard shots, just a few. Then we saw our principal coming at us and yelling at us to go in the gym. They had locked the doors and as we were walking, we saw bodies laying on the ground. police say two of their classmates, age 11 and 13, wearing camouflage clothing, had been lying in wait in a wooded area near the school. They opened fire. They were arrested. High-powered rifles, pistols. They were heavily armed. as the heartbreaking news spread through Jonesboro, the town erupted with fear, panic, concern. People started rushing into the school. Parents were freaking out. It was very chaotic. Everyone was crying. I saw folks with blood on their clothes. the governor of Arkansas spoke philosophically and with a sense of resignation about the times in which our children live. It makes me angry not so much at individual children who have done it as much as it does angry at a world in which such a thing can happen. and this evening, Jonesboro, Arkansas, is wondering why it had to happen here.
