The brother of 64-year-old Stephen Paddock said he's "completely dumbfounded" by the shooting at a country music concert Sunday night, which is the deadliest in modern U.S. history. Eric Paddock told the Orlando Sentinel newspaper that he can't understand what happened. Mesquite Police Chief Troy Tanner says Stephen Paddock owned a single-family home in Sun City Mesquite, a retirement community along the Nevada-Arizona border. He lived there with Marilou Danley, 62. Police say they don't believe she was involved.
