The gunman who killed at least 50 people and injured more than 200 others at a Route 91 Harvest country music festival Sunday has been identified as 64-year-old Stephen Paddock from Mesquite, Nevada, NBC News reports.
The shooter was firing rounds from the 32nd floor of the Mandalay Bay.
Fox News is reporting Paddock killed himself.
Marilou Danley, his 62-year-old roommate and who he was seen in a car with before the attack, has been taken into custody.
Paddock was known to local law enforcement, NBC News reports. No additional details were immediately available, however.
