Heights Reaction Center park where it all happened. Mola lenghi has more. Reporter yes. Witnesses described several men ran through here, exchanging gunfire as children were playing on this popular playground. This is a place where you should have a happy face, not be shielding children from bullets. Reporter the Columbia Rec Center playground was happy until children and parents heard what they first othought were fireworks. Then this mother, who didnt want to be identified, came to a terrifying realization. I think two or three young men, and i saw a gun, which is when i realized it was not fireworks. Reporter she heard half a dozen gunshots and everyone started scattering. There were babies all over the park. We didnt even know where to run. Reporter she said when the shots rang out, parents grabbed any child they could reach, running behind cover, behind trees, bushing and sheds. You dont expect to run and collect children on a day at a park because you are running from gun shots.
