The brother of the man who killed at least 50 people at an outdoor music festival on the Las Vegas Strip says he's "completely dumbfounded" by the shooting, which is the deadliest in modern U.S. history.
In a brief interview with the Orlando Sentinel, Eric Paddock says he can't understand what happened. He also said he's made a statement to police.
Country music star Jason Aldean was performing Sunday night at the end of the three-day Route 91 Harvest Festival when the gunman opened fire from inside the Mandalay Bay Hotel and Casino.
Authorities say 64-year-old Stephen Craig Paddock killed himself after the shooting. Police have not yet determined a motive.
