What happened inside the shooter’s suite at the Mandalay Bay hotel

LAS VEGAS — When retiree Stephen Paddock checked into his 32nd-floor hotel suite at the Mandalay Bay Resort and Casino last Thursday, nothing appeared unusual.

Paddock had booked room 32135, described by Las Vegas Metropolitan Police Department Sheriff Joseph Lombardo as one large suite with uninterrupted views of the Las Vegas Strip.

The former accountant would’ve had a clear view of the Route 91 Harvest Festival, a 3-day country music event taking place in an open-air, ground-level venue across the Strip, some 400 yards away from his hotel.

On Sunday night, as the crowd of about 22,000 people listened to headliner Jason Aldean below, Paddock smashed two windows of his hotel suite — one in the front and one on the corner — and fired into the crowd, ultimately killing 59 and injuring hundreds of others.

The attack was the deadliest mass shooting in modern US history.

The hotel suite

Housekeepers said they “saw no signs of anything” suspicious in the two-room suite, Nevada Rep. Dina Titus told CNN.

Paddock had 23 guns inside the suite, as well as hammers, LVMPD Assistant Sheriff Todd Fasulo said. The arsenal “was pretty well hidden,” Titus said.

The gunman had brought “in excess of 10” suitcases to his room over several days, Lombardo told reporters Monday. Authorities believe Paddock brought the weapons into the hotel by himself, but they did not provide specifics.

The raid

As the first shots rang out Sunday, first responders realized that the gunfire was raining down on the crowd from a vantage point up high. “It’s coming out a window,” a first responder shouts on dispatch audio obtained by CNN.

Attention soon focused on the Mandalay Bay hotel, several floors up and several hundred feet away.

CNN law enforcement analyst Art Roddick said he was struck by the planning that went into the attack.

“Firing from an elevated position is always what you want to do, so I would not be surprised if we have some video of him actually standing in that venue looking up at Mandalay Bay and trying to figure out which room is going to give him the best advantage.

“You can see those windows are knocked out, one in the front and one in the corner, which gave him two different angles to shoot from and that’s all part of this planning,” Roddick said.

The presence of other hotel guests in the rooms surrounding Paddock’s meant that police couldn’t return fire from the ground, he explained.

Police entered the hotel to begin working their way to the shooter’s sniper nest.

“A team of six officers that approached security, they went up the elevators after discussing the situation with the security and obtaining intelligence,” Lombardo said.

“And they checked each floor by floor until they located where they believe to be the room,” the sheriff said.

High up on the hotel’s residential floors, a first responder radioed in: “I’m inside the Mandalay Bay on the 31st floor, I can hear automatic fire coming from one floor ahead… one floor above us.”

“Subsequently they approached the room, received gunfire, they backed off and SWAT responded,” Lombardo said.

Las Vegas Metropolitan Police Department Undersheriff Kevin McMahill said once the first responders had “isolated this individual to the two rooms, our SWAT team used the explosive breaching to go in and confront the individual.”

A SWAT officer is heard on police radio: “We need to pop this (door) and see if we get any type of response from this guy. See if he’s in here or if he’s actually moved somewhere else.”

Once inside the room, police found the shooter dead, apparently from a self-inflicted gunshot. Lombardo said police believe Paddock “killed himself prior to our entry.”

The attack was a threat police could not have prepared for, McMahill said.

“These folks were attacked by a man from 32 stories up with automatic rifle fire and so I don’t really know how you plan for that. We just didn’t see it coming.”
