USA –  Norman Casiano froze, certain that the gunman was standing inches from him.

Casiano and dozens of other patrons at the Pulse Nightclub had crammed into a bathroom stall to hide from the shooter. And now, there was a figure looming right outside their bathroom stall door. More shots rang out. Then the person standing in front of the stall collapsed.

“It was another patron of Pulse, and he was bleeding,” Casiano said. The victim had been shot while looking for a place to hide. Casiano glanced at the floor to see a pool of blood spreading. Then, he heard it — a laugh. “It didn’t sound like a person,” Casiano said of the gunman. “He didn’t speak. The only sound we heard was the laugh.” To Casiano, it was the sound of ‘pure evil.’ “That’s what it sounded like. It was like a laugh of satisfaction like ‘I’m doing what I came here to do,” he told CNN’s Anderson Cooper. (CNN/photo: cnn.com)…[+]
