Gunman seemed amused by killing a victim, witness says

Witness: Begging for their lives made gunman more violent

CNN —  

Norman Casiano crawled into a bathroom and wedged himself into a stall, crammed with at least a dozen people. They were hiding, crying and saying prayers under their breath.

Gunfire replaced the blaring music. Glass shattered. People screamed. The acrid smell of gunpowder filled the air.

“Please don’t let this be where I go,” Casiano prayed.

Casiano froze, certain the gunman was inches away. A figure loomed outside the stall door.

The shots sounded louder. They were getting closer. A man outside the stall collapsed in a pool of his own blood.

Casiano heard a laugh. The sound of “pure evil,” he said. “It didn’t sound like a person.”

The gunman, later identified as Omar Mateen, didn’t utter a word. There was another bloodcurdling laugh.

“It was like a laugh of satisfaction,” Casiano told CNN’s Anderson Cooper.

Mateen fired a round into the stall door.

“Please, please, please don’t shoot!” some victims pleaded.

“Please don’t do this. Let us go!”

Mateen aimed his pistol over the bathroom stall and opened fire. Casiano was hit twice and fell over. Many of those he hid with were killed.

Satisfied with the silence, the gunman left.

“One of the first things I hear when I close my eyes are guns, bullets hitting the floor and that laugh,” Casiano said.

In a bathroom stall: ‘blood was everywhere’

It was Patience Carter’s first trip to Florida, and Pulse came up in a Google search of Orlando nightclubs.

“We just went from having the time of our lives to the worst night of our lives all within a matter of minutes,” Carter told reporters Tuesday.
