 LAS VEGAS (AP) — A gunman on the 32nd floor of a Las Vegas Strip casino opened fire on an outdoor music festival, killing at least 20 people — including two off-duty police officers — and wounding more than 100, officials said early Monday. 
 
 Country music star Jason Aldean was performing on stage when the shots began ringing out Sunday night at the Route 91 Harvest Festival. 
 
 Officers confronted the suspect on the 32nd floor of the Mandalay Bay Hotel and Casino across the street from the concert and he was killed, Clark County Sheriff Joseph Lombardo said. Authorities did not release the suspect's name but said he is a local resident. 
 
 Concert-goers reported hearing what they described as automatic gun fire during the shooting. 
 
 Lombardo said they believe this was a "lone wolf" attack but said they were looking for a roommate of the dead suspect as a person of interest. 
 
 The two slain off-duty officers were attending the concert, Lombardo said. Another off-duty officer was in critical condition and another was wounded, Lombardo said. 
 
 Several officers from California were attending the music festival. A Bakersfield Police officer was shot and taken to the hospital with non-life threatening injuries. 
 
 Hours after the shooting, Aldean posted on Instagram that he and his crew were safe and said the shooting was "beyond horrific." 
 
 Kodiak Yazzie, 36, said he and his girlfriend were watching Aldean's performance when he heard what sounded like fireworks. The music stopped temporarily and started up again before another round of pops sent the performers ducking for cover and fleeing the stage. 
 
 Thousands fled as bursts of gunfire could be heard for more than five minutes, Yazzie said. 
 
 Jose Baggett, 31, a Las Vegas resident, said he and a friend were in the lobby of the Luxor hotel-casino — directly north of the festival — when people began running. He said people were crying and as he and his friend walked away, they encountered police checkpoints where officers were carrying shotguns and assault rifles. 
 
 "There were armored personnel vehicles, SWAT vehicles, ambulances, and at least a half-mile of police cars," Baggett said. 
 
 Witnesses said they saw multiple victims and dozens of ambulances near the concert venue. Some attendees later huddled in the basement of the nearby Tropicana hotel-casino. 
 
 Officers carrying assault rifles ran into the Mandalay Bay Hotel and Casino. 
 
 Authorities shut down part of the Las Vegas Strip and Interstate 15. Flights were temporarily halted at McCarran International Airport because of the shooting, the airport said on its verified Twitter account.

 In loopy yet neat handwriting, the woman wrote detail after detail about what she saw the final night of the Route 91 Harvest festival. 
 
 It was about an hour after sunrise Oct. 2 as pen swirled across paper — not yet a day since she saw her friend die. 
 
 Her account is one of hundreds that Las Vegas police released Wednesday, totaling more than 1,200 pages of witness statements from the mass shooting. Her name was redacted from copies released to the media. 
 
 Most statements — like the anonymous woman’s account — describe the chaos and bloodshed of friends, family and strangers. Many descriptions take up several pages. Some only fill a few lines. 
 
 “I was standing several feet away from the stage (do not know the distance),” the woman first wrote. Here, her letters stand straight and tall, absent the lean of cursive penmanship. 
 
 “I heard pop pop pop pop. …” she wrote. “I turned around to see if anyone shot firecrackers.” 
 
 A few seconds later, she heard “pop pop pop pop” again. 
 
 Her handwriting was still shipshape as she described the moment she realized those sounds were gunfire. 
 
 “People started screaming and saying, ‘get down, get down, down now!’” she continued. “My friend was next to me, and she was down too.” 
 
 Together, they waited a few minutes as the gunfire kept popping. Then the woman got up and told her friend to start moving. “But she was not moving,” the woman wrote. 
 
 Click to see the handwritten statement 
 
 Her handwriting begins to stretch here. Her letters appear a little bigger. Her words are slightly more spaced out on the page. 
 
 “I was checking her pulse, her lips were blue, and her eyes did not move,” she wrote. 
 
 A man nearby “started doing chest compressions” on her friend as others “were yelling to get off the field.” 
 
 The anonymous author took cover, but after a few moments, she ran right back to her friend. 
 
 “I asked her again and again to get up and move but she was not responsive,” she wrote. “I stayed next to her and tried to find her pulse again but was not able to find it.” 
 
 Two men then approached. One checked her friend and said, “NO PULSE,” then placed a red bandana over the friend’s face. 
 
 The woman’s handwriting is large now. Some letters take up three lines on the official document, titled “VOLUNTARY STATEMENT.” 
 
 She tried to find her friend in the “medical area” later that night, she wrote, but did not see her. 
 
 “I stayed there for a while,” her last line reads, “and then went to my room at Tropicana.” 
 
 Trauma of thousands 
 
 The statements released Wednesday paint a detailed picture of the trauma thousands experienced the night of the mass shooting. 
 
 They also mark the first records of their kind released since the Oct. 1 tragedy, which left 58 people dead and hundreds more wounded. 
 
 While all the documents came from the Metropolitan Police Department, the source of the material released Wednesday varies. 
 
 Some documents are topped with letterheads that read “Federal Bureau of Investigation,” “Dignity Health St. Rose Dominican” or “Henderson Police Department.” 
 
 At least one document lists a police department in Texas, which interviewed a woman who was shot in the foot but managed to fly home and then seek treatment, since many Las Vegas area hospitals were overwhelmed. 
 
 One statement, taken by a Henderson police officer, was that of Mandalay Bay security guard Jesus Campos, who was shot in the leg in the 32nd-floor hallway — the same hallway as the gunman’s suite. 
 
 The document — like all others — is redacted, and Campos’ name is not visible. But the details in the handwritten statement match details Metro previously has released about Campos. 
 
 “Shots were fired as I was leaving and I got hit on my left calve (sic),” according to the guard’s statement, which indicates he then called for backup. 
 
 The statement was only a page long. Another document, which appears to be a transcribed interview between Campos and Metro investigators, suggests Campos did not “frequently” work in the Mandalay Bay tower where he was shot. 
 
 “It just happened to be that day that I was working those floors,” he said, according to the document. 
 
 Another employee, described only as “sec dispatch,” described coming in to work Oct. 3 and reviewing “any recording of the ‘sec/engineering’ transmission.” 
 
 The employee noted that, as he was copying the files onto a disc, he discovered “the time stamp was incorrect.” 
 
 “Time stamp was 20-30 min ahead of actual time,” the employee wrote. He then indicated he “corrected time to match” the rest of the security system. 
 
 “No other system time were adjusted at this time,” the employee also wrote. 
 
 In the first two weeks after the shooting, Metro revised its timeline of events at least twice in a series of news conferences. 
 
 According to a separate document, a Metro investigator asked a Mandalay Bay security employee in the days after the tragedy if the hotel had a policy regarding how to handle evidence related to criminal investigations. 
 
 “No, we don’t,” the employee replied. 
 
 Small details 
 
 It remains unclear how many witness interviews were completed throughout the mass shooting investigation. 
 
 The statements released Wednesday were mostly collected in the days immediately after the shooting, according to the dates on the documents. Several include transcriptions of interviews that took place in local hospitals. 
 
 Even the shortest of statements reveal small, painful details. 
 
 A pregnant woman wrote about running for her life that night with her husband. 
 
 “My body wasn’t responding well,” the woman, who was six months along at the time, wrote. “I was very scared. My whole body felt very heavy.” 
 
 Several people pointed out they tried to call 911 but could not get through. 
 
 When the gunshots started, one woman was using a festival restroom. Her wife pounded on the port-a-potty door. 
 
 She bolted out of the bathroom and began running with her wife. 
 
 The couple made it all the way to the Tropicana, where they hid behind air conditioners on the roof of the hotel, praying together high above the Strip. 
 
 Legal battle 
 
 The document dump came about two weeks after Metro released body camera footage from two of the officers who helped breach the gunman’s Mandalay Bay suite the night of the shooting. The first officer to breach the room, Levi Hancock, did not activate his camera. 
 
 Those clips were the first of many that Las Vegas police must release over the next several months in compliance with a court order. 
 
 The order came after a lengthy court battle in which the Las Vegas Review-Journal and other media organizations sued for Metro to release records from the mass shooting investigation, including body camera footage and 911 calls. 
 
 It remains unclear when the next batch of records will be released.

 LAS VEGAS (AP) — A gunman perched high on the 32nd floor of a Las Vegas Strip casino unleashed a shower of bullets down on an outdoor country music festival below, killing at least 50 people and wounding more than 200 as tens of thousands of frantic concert-goers screamed and ran for their lives, officials said Monday. It was the deadliest mass shooting in modern U.S. history. 
 
 Country music star Jason Aldean was performing Sunday night at the end of the three-day Route 91 Harvest Festival when the gunman opened fire across the street from inside the Mandalay Bay Hotel and Casino. SWAT teams quickly descended on the concert and the casino, and officers used explosives to get into the hotel room where the suspect was inside, authorities said. The gunman died at the scene and was identified by Clark County Sheriff Joseph Lombardo as Stephen Paddock, 64. A motive was not immediately known. 
 
 Aldean was in the middle of a song when the shots came rapidly: Pop-pop-pop-pop. Video of the shooting then showed Aldean stopping and the crowd getting quiet as if they were unsure of what had just happened. The gunman paused and then fired another volley of muzzle flashes from the gold glass casino as more victims fell to the ground while others fled in panic. Some said they hid behind concession stands and other crawled under parked cars. 
 
 Kodiak Yazzie, 36, said the music stopped temporarily when the first shots began and the tune even started up again before the second round of pops sent the performers ducking for cover and fleeing the stage. 
 
 "It was the craziest stuff I've ever seen in my entire life," Yazzie said. "You could hear that the noise was coming from west of us, from Mandalay Bay. You could see a flash- flash- flash- flash." 
 
 Thousands in the crowd fled as the bullets ran rampant. Monique Dumas from British Columbia, Canada, said she was at the concert, six rows from the stage when she thought she heard a bottle breaking, and then a burst of popping sounds that may have been fireworks. She said as she made her way out, it was "organized chaos" as everyone fled. "It took four to five minutes and all that time there was gunfire." 
 
 In addition to Paddock, police said they located a woman who may have been his roommate — Marilou Danley, 62. Lombardo said they believe this was a "lone wolf" attack. 
 
 "It's a devastating time," Lombardo said. 
 
 Police shut down the usually busy Las Vegas Boulevard and authorities across the state and federal ranks converged onto the scene as dozens of ambulances ferried those struck by gunfire. Nearby Interstate 15 and flights at McCarran International Airport were briefly closed. Hospital emergency rooms were jammed with victims delivered by ambulance. Others loaded the wounded into their cars and drove them to hospitals. 
 
 Jose Baggett, 31, of Las Vegas, said he and a friend were in the lobby of the Luxor hotel-casino — directly north of the festival — when people began to run, almost like in a stampede. He said people were crying and as he and his friend started walking away minutes later, they encountered police checkpoints where officers were carrying shotguns and assault rifles. 
 
 "There were armored personnel vehicles, SWAT vehicles, ambulances, and at least a half-mile of police cars," Baggett said. 
 
 Among those killed were two off-duty police officers who were attending the concert. Two on-duty officers were wounded, including one who underwent surgery and was upgraded to stable condition early Monday, police said. 
 
 Hours after the shooting, Aldean posted on Instagram that he and his crew were safe and said the shooting was "beyond horrific." 
 
 "It hurts my heart that this would happen to anyone who was just coming out to enjoy what should have been a fun night," Aldean said. 
 
 President Donald Trump extended condolences to the victims and their families. 
 
 In a tweet Monday, Trump offered "My warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting. God bless you!" 
 
 White House spokeswoman Sarah Huckabee Sanders said Trump was "briefed on the horrific tragedy in Las Vegas." 
 
 Sanders said that "we are monitoring the situation closely and offer our full support to state and local officials. All of those affected are in our thoughts and prayers." 
 
 The shooting at the sold-out Route 91 Harvest festival was the deadliest mass shooting in modern U.S. history. Forty-nine people were killed when a gunman opened fire at the Pulse nightclub in Orlando in June 2016. 
 
 Sunday's shooting came more than four months after a suicide bombing at an Ariana Grande concert in Manchester, England, that killed 22 people. Almost 90 people were killed by gunmen inspired by Islamic State at the Bataclan concert hall in Paris during a performance by Eagles of Death Metal in November 2015.

– One of the many jarring videos to emerge from the Sunday night mass shooting in Las Vegas shows a defiant man standing and taunting the gunman while most of those around him were on the ground or trying to find cover. You can see the video here, but note that it's disturbing. (The man emerges around the 1:10 mark.) "Come on," he can be heard yelling, while gesturing with his arms in the direction of the source of the shots. As the Daily Dot notes, many commenters have criticized the "hyper-macho response," but is it possible the man inadvertently had the right idea in staying upright? A story at the New York Times that digs into the unusual nature of this attack observes that many people instinctively dropped to their stomachs when the bullets began flying. That's usually wise, "but on Sunday night, the decision potentially put them at greater risk," per the account by CJ Chivers, Thomas Gibbons-Neff, and Adam Goldman. The reason is that the gunman was firing from such a high vantage point, the 32nd floor of the hotel across the street. Any "inaccurate shots—the sort common to rapid or hurried fire, which typically sail high or strike the ground short—could still plunge into areas where people were huddled." Still, the choice was stark for concertgoers in the chaos. One puts it this way to the Times: “Either run and get shot and die, or stay and get shot and die.”
