An Iraq War veteran who was staying two floors below the Vegas shooter in the Mandalay Bay Resort and Casino reflected on the amount of time it took responders to reach the hotel.
Chris Bethel used his military training to almost immediately identify the types of shots being fired.
"I could just hear the gun shots, continuously. Just full automatic," Bethel told CBS Dallas-Fort Worth. "There was explosions going off. It was like a bomb just went off, man. And then there were more gun shots."
Bethel, who resides in Fort Worth, Texas, was in Vegas for an IT conference when Stephen Paddock, 64, opened fire on thousands of people attending a country music festival.
Chris Bethel helped police pin down Paddock's location after the gunfire started.
"I could just see everybody running and I kept looking at the windows to see if I could see any kind of muzzle flash to see if I could see where the shooter was," Bethel told CBS. "I crouched by my front door in hopes that I might get the opportunity to see the shooter if he ran by and I could identify him."
Bethel could even tell when Paddock was changing rounds and using different guns.
"Changing weapons, changing calibers," Bethel told CBS. "You can hear the difference in the gunshots of the different rifles that he is shooting."
"About 10 minutes later, the Las Vegas Police Department called me to let me know that the shooter was on the 32nd floor, Room 135, and that they had gotten him," Bethel added.
Now, Bethel is back home in Texas. However, he still has many questions about the time it took for the shooter to be taken out.
"I feel like I didn't do enough. I feel like I couldn't get a hold of somebody quick enough to let them know. And it felt like it took them too long to get over there to take him out. To get him. And it's actually eating me up inside," Bethel told CBS. "I just need to go home. That's my thing. I need to go home to my family and just process all of this."
Based on a timeline published by Newsweek, police arrived on the 32nd floor of the hotel about 11 minutes after Paddock started shooting. However, it took an additional hour for SWAT members to report the suspect was down.
