A Mandalay Bay security guard was one of over 500 individuals injured in the deadliest mass shooting in modern U.S. history.
On Oct. 1, Stephen Paddock opened fire on a crowd of 22,000 at a country music festival from a room on the 32nd floor of the Mandalay Bay hotel, according to CNN. Paddock killed at least 58 people before also killing himself.
According to Clark County Undersheriff Kevin McMahill, the first call reporting shots came in at about 10:08 p.m. Pacific time on Oct. 1 and the shooting did not stop until 10:19 p.m. He said that, in total, the shooting lasted anywhere from 9 to 11 minutes.
In a video posted to Global News, Clark County Sheriff Joseph Lombardo states that Paddock engaged security at the hotel.
"He shot through the doorway and struck a security guard," Lombardo says.
"No, he wasn't," he later elaborates when asked if the security guard was killed. "He was shot in the leg."
In a separate video also posted to Global News, Lombardo also praises security at the hotel.
"The Mandalay Bay security was fantastic," he says in the video. "I don't want anybody assuming that they are unsafe by, you know, staying at one of our hotels. We would not have engaged this individual in the time lapse that we did without their assistance."
"We received information via their dispatch center, and/or their operation center, their call center, from individuals staying within the Mandalay Bay that helped us locate where this individual was sequestered," he continues.
Police believe that Paddock was acting alone in the shooting, but still do not have a clear idea as to his motive, accordion to CNN. Before the shooting, he had faced no notable previous criminal charges.
"There's all kinds of things that surprise us on these kinds of events, that's the one on this one," FBI Deputy Director Andrew McCabe told CNBC, according to CNN. "This individual ... didn't leave the sort of immediate thumbprints you find on these kinds of attacks."
McCabe also told CNN that the FBI is going through Paddock's communications, financial records, associates and video surveillance to find a potential motive.
Authorities encountered 23 guns in Paddock's hotel room in addition to another 19 at his home, located in Mesquite, Nevada. He had bought firearms in the past, and though it appeared he had done so legally, an official said at least one rifle had been altered to function as an automatic weapon.
