At least 59 are dead and more than 500 injured in the deadliest mass shooting the United States has ever seen. Shortly after 12 a.m. (CST) Monday morning, 64-year-old Nevada resident, Stephen Paddock, began shooting down from his 32nd story Mandalay Bay Resort and Casino hotel room window on the Route 91 Harvest Festival in Las Vegas.

Taking aim at the estimated 22,000 people attending the country music festival, Paddock fired hundreds of rounds down at the crowd.

One former Redhawk was in the area when the event unfolded. Senior Reggie Chaney, whose family still lives in Frisco, transferred to Findlay Prep in Las Vegas after his sophomore year to play basketball for the prep powerhouse.

“Although I wasn’t right near the area of where it happened, it’s kind of shocking that it was not too far from me, and that a tragic event like that can happen anywhere at anytime,” Chaney said via text.

Findlay Prep is only 12 miles from the scene of the shooting, leaving Chaney and his teammates deeply impacted.

“It’s tragic, in a way,” Chaney said via text. “People came here to have a good time and instead suffered something really tragic, which is sad and unfortunate.”

According to CNN, Paddock had 16 rifles stashed with him in his hotel room, which allowed the shooting to last approximately 10-15 minutes.

One concertgoer, Carly Krygier, who was at the concert with her four year old daughter, spoke to CNN about what happened when she realized the sounds were, in fact, gunfire.

“I put the baby on the ground and got on top of her,” Krygier said to CNN. “When we heard a little break, we ran to the bleachers that were just behind us I tried to tuck her as close to the end so she was as protected as possible.”

As shots continued to be fired, people tried to get to cover as quickly as possible.

“Every time we heard shots, we’d hit the ground and just stay there until they would stop for about 30 to 45 seconds,” Shelly Mallory told CNN.  “And then we would run as fast as we could. I thought the shooting would never end.”

When police found the room of the shooter, Paddock reportedly shot through the door at police but was dead when police finally got to him in what is being preliminarily labeled as a self-inflicted wound.

The police investigation is just beginning, but even those closest to Paddock are surprised.

“We have no idea how or why this happened,” brother Eric Paddock said to ABC News.
