A gunman on the 32nd floor of a Las Vegas Strip casino opened fire on an outdoor music festival, killing at least 50 people — including police officers — and injuring more than 400 in the largest mass shooting in U.S. history, officials said Monday.
Police said the shooter, 64-year-old Stephen Craig Paddock of Mesquite, Nevada, was found dead in a hotel room with as many as 10 firearms.
He was already dead, an apparent suicide, when police burst into his 32nd floor room at the Mandalay Bay Hotel and Casino across the street from the concert site, authoritities said.
Country music star Jason Aldean was performing on stage when the shots began ringing out Sunday night at the Route 91 Harvest Festival.
Authorities say they have located 62-year-old Marilou Danley, the suspect's wife, who was wanted as a person of interest in this incident.
Concert-goers reported hearing what they described as automatic gun fire during the shooting.
Clark County Sheriff Joseph Lombardo said they believe this was a “lone wolf” attack.
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.
President Donald Trump took to Twitter shortly after 7 a.m. E.T. to offer his sympathies.
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.
