At about 10:08 p.m. on Sunday, Oct. 1, a 64 year old man named Stephen Paddock shot from the Mandalay Bay Resort and Casino from the 32nd floor into a crowd several hundred feet away. The crowd was attending a Route 91 Harvest Festival concert. Out of the 22,000 concert attendees who were shot at by Paddock, nearly 500 people were injured, with 58 dead. This was the deadliest shooting in modern US history, with the 2016 Pulse nightclub shooting in Orlando, Florida being the previous deadliest, with 49 people killed. Witness Rachel de Kerf told CNN about the shooting.

“The gunshots lasted for 10 to 15 minutes,” Kerf said. “It didn’t stop.”

When the police officers breached the hotel room that Paddock was shooting from, they found him dead in his room. Authorities believe that he killed himself.
