At least 59 people were killed and 527 injured on the Las Vegas Strip marking the deadliest mass shooting in modern US history.
Here’s everything we know about the tragedy so far:
1. Festival attendees were targeted.
A crowd had gathered to watch country musician Jason Aldean perform when the shots rang out. Aldean’s performance was part of a three-day festival, the Route 91 Harvest festival.
According to USA Today, the fest reportedly attracted 30,000 attendees. The incident occurred during the fest’s final night, around 10 pm Sunday (1 am Monday EST)
2. The shooter was American.
The gunman has been identified as Stephen Paddock, a 64-year-old man from Mesquite, Nevada. According to USA Today, police believe he acted as a “lone-wolf.” Though, many are calling it an act of terrorism. He is described as a white male, according to a police press release. Paddock worked as an accountant or auditor, ABC News reports. He also had a hunting license in Alaska.
3. Paddock shot from a hotel room.
Paddock shot from a 32nd floor of a hotel, the Mandalay Bay Resort and Casino. According to NBC News, several weapons were found inside the hotel room. A motive has not yet been reported.
4. The gunman is dead.
The Associated Press reports police used explosives to enter the gunman’s hotel room. He died on the scene. Police believe he may have killed himself.
5. There’s another person of interest.
Police have been looking for Paddock’s roommate, Marilou Danley, 62. CNN reports that she might have been traveling with the suspect. Police said they are confident but “not 100 [percent] sure” they’ve found her.
6. Automatic weapons are suspected.
A CNN law enforcement analyst James Gagliano said he believes, based on the audio of the attack, that the shooter used a fully automatic weapon.
"Automatic weapon(s) like that -- had to be numbers of magazines or a very large drum, it sounded to me like a belt-fed weapon, a military-style weapon and then to be shooting down, to use the analogy, it was like shooting fish in a barrel in that space," Gagliano said.
7. Some concert-goers thought it was fireworks.
In one video, you can hear some people mistaking the gunshots for fireworks.
“They’re not real gunshots,” one man said. “...It’s fireworks. It’s fireworks.”
Others feared a stampede. “We’re going to get trampled if we don’t go,” someone can be heard saying, according to USA Today.
8. It was complete chaos.
Witness Meghan Kearney told MSNBC, “People started screaming that they were hit… When we started running out there were probably a couple hundred [people] on the ground. … People kept dropping and dropping. … People were getting shot one foot away from us," she said. “People were trying to save their friends. There were gunshots everywhere. Helping them would’ve meant that we got shot, too.”
People were hurt during a stampede that followed the shooting. Names of victims have not been released. Facebook has set up a crisis response page to help people find their loved ones.
