A gunman in a high-rise hotel opened fire on a country music festival on the Las Vegas Strip late Sunday, killingÂ at least 50 people and wounded more than 200 in the deadliest mass shooting in modern American history.
The gunman, identified as Stephen Paddock, was laterÂ killed during a standoff with police on the hotelâs 32nd floor, Sheriff Joseph Lombardo told reporters. NBC and others reported that Paddock was 64.
The carnage surpassed the death toll of 49 people at an Orlando nightclub when a gunman believed inspired by the Islamic State opened fire in June 2016.
Under the neon glow and glitz of the Vegas Strip, concertgoers dove for cover or raced toward shelter through a sea of water bottles, hats, shoes and other items lost in the stampede as a hail of gunfire rained down from the Mandalay Bay Hotel and Casino around 10 p.m. local time.
Police believe Paddock, a local resident, wasÂ a âlone wolfâ attacker. He did not give further details, however, on Paddockâs background or possible motives.
âWe have no idea what his belief system was,â Lombardo said. âRight now, we believe he was the sole aggressor and the scene is static.â
But a search was underway for a woman described as the suspectâs âtraveling companion,â he added.
The gunman was previously known to local police for past run-ins with law enforcement, according to people familiar with the investigation.Â Recordings of the attack suggest the suspect used an automatic weapon.
The shooting occurred at the end of the Route 91 Harvest Festival, a three-day country musicÂ concert held over the weekend that reportedly drew 30,000 attendees. The concert grounds areÂ adjacent to Mandalay Bay. The shots began as Jason Aldean, one of the final performers, was playing.
Lombardo said authorities were searching for a woman named Marilou Danley.Â The sheriff said authorities were also looking for two cars, a Hyundai TusconÂ and a Chrysler Pacifica Touring, both with Nevada plates.
âItâs a devastating time,â Lombardo said at a news conference early Monday. âWe have responded to the scene, and weâre doing the best we can to provide safety to the survivors.â
A witness to the shooting, Ivetta Saldana, told the Las Vegas Review-Journal that Aldean was rushed offstage when the shots rang out. âIt was a horror show,â she said. âPeople were standing around, then they hit the floor.â
Aldean posted an Instagram message that he and his crew were safe. The scene, he wrote, was âbeyond horrific.â
Videos posted to Twitter from people claiming to be witnesses showed people screaming and runningÂ for cover amid the sound of gunshots. The shooting continued intermittently for more than five minutes, according to the Associated Press.
âThe gunfire never ended, it seemed like,â concert attendee Rachel Dekerf told CNN. âIt just went on and on and on.â
Mike McGarry, a 53-year-old financial adviser from Philadelphia, said he threw himself on top of his children as shots rang out. âTheyâre 20. Iâm 53. I lived a good life,â McGarry told the Reuters news agency. The back of his shirt had foot marks from people who stepped over him in the crush to flee.
President Trump tweeted âcondolences and sympathiesâ for the victims and their families hours after the shooting.
My warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting. God bless you!

âThe president has been briefed on the horrific tragedy in Las Vegas. We are monitoring the situation closely and offer our full support to state and local officials,â White House press secretary Sarah Sanders said in a statement Monday morning. âAll of those affected are in our thoughts and prayers.â
Among those wounded was an off-duty officer with the Bakersfield Police Department in Southern California, who was taken to a hospital for non-life-threatening injuries, according to a newsÂ statement. Several of the departmentâs officers were off-duty and attending the concert when the gunfire erupted.
The Las Vegas police said Monday morning that two on-duty police officers were injured during the shooting. One of them is in stable condition after surgery and the other sustained minor injuries.
Multiple flights bound for the McCarran International Airport, about 10 miles from the shooting scene, were diverted after the attack, the airport tweeted.Â All other planes were temporarily grounded, withÂ a few flights resuming Monday morning.
The Route 91 Harvest Festival has been held for the past four years on a 15-acre lot across an intersection from Mandalay Bay. The concertâs main stage is situated near the northeastern side of theÂ gold-colored casino and high-rise hotel complex, whichÂ towers more than 400 feet above the Strip.
Three hours after the shooting, Aldean said in an Instagram post: âMy Thoughts and prayers go out to everyone involved tonight. It hurts my heart that this would happen to anyone who was just coming out to enjoy what should have been a fun night.â
Security measures at many music venues have been boosted in recent years after concerts have been hit by terrorism strikes.
In May in northern England, a bomb exploded at a concert by American singer Ariana Grande in Manchester, killing 22 people in an attack carried out by the suspected Islamist militant. In Paris, Islamist attackers opened fire at a rock concert in November 2015 as part of coordinated attacks that left 130 dead.
In June, a 42-year-old man from the Philippines opened fire at a casino in Manila, killing 37 people. Police said the attack was motivated by gambling debts and other personal problems facing the gunman, who killed himself with a self-inflicted gunshot wound. The Islamic State had claimed responsibility for the attack, but officials repeatedly denied it was terrorism-related.
