More than 50 people have been killed and more than 500 wounded during a shooting at an outdoor country music festival on the Las Vegas Strip Tuesday night (late Sunday US time).
Dozens of patrol vehicles descended on the Strip after authorities received reports of an active shooter near the Route 91 Harvest Festival.
Police confirmed at a press conference that the suspect, a local man, had been killed by police. They later named him as 64-year-old Stephen Paddock.
According to Mesquite police, Paddock lived in a retirement community, with no prior run-ins with law enforcement.
They said he had a female companion they wanted to speak to and identified her as Marilou Danley. They later said they were reasonably confident "but not 100% sure" that she had been found.
Police said they believed it was the actions of a "sole aggressor" on the 32nd floor of Mandalay Bay Resort and Casino.
