MONDAY, Oct. 2 — Joshua Moore had just finished a dinner of pizza near his Las Vegas strip hotel and preparing to call an Uber for birthday night out on the town when a crowd of people came running toward him screaming about shooters.

The Detroit attorney turned with his friend and ran with the crowd.

“It was chaos,” he said. “It was crazy. Everyone was saying there were seven shooters. There were bomb threats. We didn’t know at all exactly what was happening.”

What was happening was the worst mass shooting in American history. At least 50 are dead and another 400 injured after 64-year-old Stephen Paddock allegedly opened fire from the 32nd floor of the Mandalay Bay hotel. Paddock shot from the window into a crowd of 22,000 attending a country music concert across the street.

Law enforcement had reported Paddock had at least 10 long rifles in his room. They report he killed himself when police broke into the room, ending the attack.

Moore said he decided to go to Las Vegas on Friday and arrived Saturday afternoon. He made that decision after plans to go to Puerto Rico, where he does legal work, fell through. His flight to the hurricane-ravaged island and American territory had been canceled Thursday.

“I was disappointed,” he said of the Puerto Rico trip. “I was looking forward to helping my friends and seeing them.”

Instead of the hurricane-ravaged island territory, Moore decided to travel to Las Vegas to visit his best friend, who lives there.

He said he ended up providing refuge to people seeking shelter from the attack in his hotel room, about a mile from the attack.

“I’ve been through a lot of crazy things before,” he said, “but this was definitely the craziest.”
