Shooting


Preparation

According to his girlfriend, Paddock repeatedly cased Las Vegas Village from different windows in their room when they stayed at the Mandalay Bay a month before the shooting. Paddock also may have considered attacking previous events. He had researched large-scale venues in cities such as

festival that ran from September 22 to 24. Paddock's Internet search terms from mid-September included "swat weapons", "ballistics chart 308", "SWAT Las Vegas", and "do police use explosives". Paddock arrived at Mandalay Bay on September 25, 2017, and booked into Room 32–135, a complimentary room on the 32nd floor. Four days later, he also checked into the directly connected Room 32–134. Both suites overlook the site of the concert at Las Vegas Village. During his stay at Mandalay Bay, Paddock spent much of his time gambling, usually at night. He interacted with employees more than ten times, including twice on the day of the shooting; an MGM Resorts International spokesperson said all the interactions were "normal in nature". Cell phone records show that he also made multiple visits to his home in Mesquite. With help from hotel bellmen, he brought five suitcases to his room on September 25, seven on the 26th, two on the 28th, on the 30th, and two on October 1.

Attack

The mass shooting occurred between 10:05 p.m. and 10:15 p.m. on October 1, 2017, which was the third and final night of the festival. When the shooting began, country music singer Jason Aldean was giving the closing performance. Shortly before 10:00p.m., hotel security guard Jesus Campos was sent to the 32nd floor to investigate an open-door alert. He attempted to open a door that provided immediate access to the floor, but found that it would not open. After Campos entered the floor, he discovered an L-shaped bracket screwed into the door and door frame, which was responsible for barring the door from opening. After reporting the discovery to his dispatch center, he heard what he thought was the sound of rapid drilling coming from Room 32-135 and went to investigate the matter. At approximately 10:05 p.m., he was hit in the right thigh by one of about 35 bullets that Paddock fired through the door of his suite. After Campos was hit, he took cover in the alcove between Rooms 32-122 and 32-124 and immediately informed the hotel by radio and cellphone that he had been shot, though he believed he had been shot with a BB or

. At the same time, maintenance worker Stephen Schuck was on the same floor to fix the door that Campos had reported as being barricaded. The already-wounded Campos encountered Schuck and told him to take cover. Schuck contacted hotel dispatchers over his radio, informed them of the ongoing shooting, and told them to call the police. Neither the

nor MGM Resorts International, the Mandalay Bay's owner, have confirmed when information about the initial shooting was relayed to the police. After Paddock used a hammer to break two of the windows in both of his suites, he began shooting through them at 10:05p.m. He ultimately fired over 1,000 rifle rounds approximately into the festival audience. He initially started out with a few single gunshots before firing in bursts that usually ranged from 80 rounds to 100 rounds. Many people in the crowd initially mistook the gunfire for fireworks. During the shooting, a security fence hindered concertgoers from fleeing the concrete lot. The gunfire continued, with some momentary pauses, over the span of ten minutes and ended by 10:15p.m. During these pauses (during reload and while the assailant was confronting Campos), most concertgoers down below were able to flee the venue. In addition to shooting at the concertgoers, Paddock fired eight bullets at a large jet fuel tank at McCarran International Airport (since renamed

, or the festival grounds. There were also multiple false reports of additional shooters at other hotels on the Strip. Officers eventually spotted multiple flashes of gunfire from the middle of the northern side of Mandalay Bay and responded to the hotel. At 10:12p.m., two officers on the 31st floor reported the sounds of gunfire on the floor above them. When officers arrived on the 32nd floor at 10:17p.m. and encountered Campos a minute later, he directed them to Paddock's room and helped others evacuate. Campos was then directed to seek medical attention for himself. Between 10:26 p.m. and 10:30p.m., eight additional officers arrived at the 32nd floor; some of those officers manually breached the door Paddock had screwed shut with the bracket. The gunfire had ceased, and the police moved systematically down the hallway, searching and clearing each room, using a master key that was provided by Campos. At 10:55p.m., the officers finished evacuating guests. At 11:20p.m., police breached Room 32–135 with explosives. Paddock was found dead on the floor from a self-inflicted gunshot wound to the head. Police then breached Room 32–134; while entering the hotel suite, an officer accidentally fired a

from his weapon, but the bullets did not hit anyone. At 11:27p.m., officers announced over the police radio that a suspect was down.


Immediate response

McCarran International Airport, adjacent to the shooting site, was shut down for several hours. Approximately 300 people entered the airport grounds as they fled from the shooting. This prompted officials to shut down all four runways. More than 25 flights were rerouted to ensure that no aircraft would be hit by gunfire, while other flights were canceled before airfield operations resumed at 12:40a.m. on October 2. Much of Las Vegas Boulevard was closed while police SWAT teams combed the venue and neighboring businesses. At approximately 2:45p.m. PDT on October 2, a state of emergency was declared in Clark County. Early on October 2, Sheriff Lombardo identified the suspect as .


Victims


Dead

As of October 2020, there were 60 deaths, not including that of Paddock. The immediate dead comprised 58 victims—36 women and 22 men—all of whom died from gunshot wounds. The oldest was 67, and the youngest was 20. Thirty-four were from California; six from Nevada; four from Canada; two from Alaska and Utah; and one each from Arizona, Colorado, Minnesota, Massachusetts, New Mexico, Pennsylvania, Tennessee, Washington, West Virginia, and Wisconsin. Thirty-one of the victims were pronounced dead at the scene, while twenty-seven died from their wounds at the hospital, with the last of those dying on October 3, two days later. Paddock's suicide was the only death at the Mandalay Bay Hotel. A 57-year-old woman from California, who had been paralyzed in the shooting, died more than two years later on November 15, 2019.

Also, an erroneous emergency services announcement made one hour after the shooting reported UMC had reached capacity and was on diversion. This confusion persisted for several hours and led to most patients being transported to Sunrise, a Level II trauma center.


Investigation

Officials from the FBI and the ATF responded to assist in the investigation. According to authorities with the Clark County Commission, the name "1 October" was declared the official title for investigations into the mass shooting.


Early reports

Investigators found hidden surveillance cameras that were placed inside and outside the hotel room, presumably so Paddock could monitor the arrival of others. The cameras were not in record mode. Police said a handwritten note found in the room indicated Paddock had been calculating the distance, wind, and trajectory from his 32nd floor hotel suite to the concertgoers he was targeting on the festival lot. At a press conference on October 4, Clark County Sheriff Joe Lombardo stated there was evidence—which he declined to discuss—that Paddock intended to escape the scene, and that he may have had assistance from an accomplice. Investigators searched Paddock's room and found a " bulletproof vest" and breathing apparatus, neither of which were used by Paddock. There have been several changes in the official account and timeline of Paddock's shooting of hotel security guard Campos. Police officials described these adjustments as "minute changes" that are common in complex investigations. In their first statement about the incident, police officials inaccurately reported that Campos arrived on the scene after Paddock began firing into the crowd. In a second statement, police officials reported, again inaccurately, that Campos was shot six minutes before Paddock began firing into the crowd. That report had been based on a 9:59 p.m. notation in a hotel security log, which in a third statement was determined to have been the time when Campos encountered the barricaded door. Sheriff Lombardo dismissed allegations that the changing timeline was the result of some kind of conspiracy between the police department, the FBI, and MGM Resorts International saying, "Nobody is attempting to hide anything in reference to this investigation. The dynamics and the size of this investigation requires us to go through voluminous amounts of information in order to draw an accurate picture."

Final investigative report

On August 3, 2018, Clark County Sheriff Joe Lombardo held a press conference on the release of the ''LVMPD Criminal Investigative Report of the October 1 Mass Casualty Shooting''. He said the 10-month investigation had revealed no evidence of conspiracy or a second gunman, and that the gunman's motive had not been definitely determined. Lombardo said "What we have been able to answer are the questions of who, what, when, where and how... what we have not been able to definitively answer is why Stephen Paddock committed this act."

s. Paddock was a high-stakes gambler who placed bets at a high enough level to earn valuable comps—free benefits such as rooms and meals. He was a familiar figure to casino hosts in Las Vegas, but was not well known among other high-stakes gamblers because he mostly played single-player video poker. He reportedly kept to himself and was a heavy drinker. Paddock had lost a significant amount of his wealth over the previous two years, but had paid off all gambling debts before the shooting.


Legal

In November 2017, a lawsuit was filed on behalf of 450 of the victims of the shooting, which claimed that the Mandalay Bay Hotel had shown

In July 2018, MGM Resorts International countersued hundreds of victims, claiming that it had "no liability of any kind" for the attack. On October 3, 2019, MGM Resorts reached a settlement of $800 million with the victims of the shooting, which was approved by a judge on September 30, 2020.


Aftermath

On the morning after the shooting, lines to donate blood in Las Vegas stretched for blocks, and wait times were as much as six hours or more. In Las Vegas alone, 800 units of blood were donated to the local blood bank in the days following the shooting, and the American Red Cross reported a 53% increase in blood donation in the two days following the shooting. It was later reported that over 15% of the blood donated in Las Vegas after the shooting went unused, prompting questions about the benefit of widespread calls for blood donation following mass shootings. Millions of dollars have also been raised to help victims and their families. A unity prayer walk and ceremony was held in Las Vegas on October 7 in honor of the dead. Speakers at the ceremony included Vice President Mike Pence and Las Vegas Mayor Carolyn Goodman. On the evening of October 15, thousands participated in a commemorative 3-mile walk between Circus Circus and Mandalay Bay. The annual Rock 'n' Roll Las Vegas Marathon took place on November 12 and was the largest event to be held in the city since the shooting. The event received a massive amount of security, which included 350 officers, counter-sniper surveillance posts, and a number of barriers composed of dump trucks, buses, and other large vehicles.

of the NHL held a tribute to the victims and honored response personnel before their inaugural home game on October 10. Later during the season, the number 58 became the first number in team history to be retired, chosen for the 58 people who died immediately or within days of the shooting. The Mandalay Bay Resort renumbered its floors, skipping floor 32. Rooms 32–135 and 32–134, the rooms rented out by Paddock, were sealed off and made inaccessible to guests. The future of the Las Vegas Village remained undetermined until September 2019. MGM Resorts International intends to create a community center, which will host sporting events. In March 2019, Las Vegas police officer Cordell Hendrex, who did not immediately respond to the gunfire but had remained in the floor below Paddock, was fired for his inaction. He was reinstated a year later following an arbitrator's ruling.

Matthew Whitaker signed a regulation banning bump stocks in the U.S., effective March 2019. The regulation bans new sales and requires current owners to surrender or destroy existing bump stocks. Eighteen Democratic U.S. Senators introduced a bill, the Keep Americans Safe Act, which would ban gun magazines that hold more than ten rounds of ammunition. Stock prices of firearms manufacturers rose the day after the shooting, as has happened after similar incidents. Investors expected gun sales to increase over concerns that such an event could lead to more stringent gun-control legislation, and possibly due to a rush of customers wishing to defend themselves against future attacks, but firearm sales did not increase after the shooting.

s have claimed that there were multiple shooters and that details of the massacre are being covered up for the sake of promoting gun control laws. After some media outlets reported that YouTube search results for information about the shooting returned links to conspiracy videos, YouTube said it had tweaked its search algorithm to promote news sources which it considered more authoritative. Some experts have said the removal of this content ironically fuels conspiracy theories by making a cover-up seem evident.
