50 Dead, 200 others injured in shooting at a music festival in Las Vegas

Las Vegas authorities say more than 50 people are dead and 200 people are wounded after a man opened fire on an outdoor concert late Sunday night. Police say the suspect's name is Stephen Paddock, 64, a local resident. They have also reportedly located 62-year-old Marilou Danley, wanted as a person of interest.

For context: If the death toll holds, this will be the deadliest mass shooting in modern U.S. history, passing the 2016 attack on the Pulse nightclub in Orlando, Florida.

Details from the scene: "The shooting happened near the Mandalay Bay Resort and Casino. Video posted online showed the country singer Jason Aldean performing outside the hotel at Route 91 Harvest, a country music festival, interrupted by the sound of automatic gunfire. The music stopped, and concertgoers ducked for cover. 'Get down,' one shouted. 'Stay down,' screamed another.
