At least 58 people were killed and more than 500 others injured after a gunman opened fire Sunday night at a country music festival across the street from the Mandalay Bay Resort and Casino on the Las Vegas Strip, authorities said.
What you need to know:
The gunman responsible for the massacre in Las Vegas first began buying guns two decades ago, a federal source said Wednesday, but the majority of the 47 guns he owned had been purchased since October 2016.
Stephen Paddock brought at least 23 weapons, mostly rifles, to the Mandalay Bay hotel room from which he opened fire on a country music concert across the street Sunday night, an attack which left 59 people dead and more than 500 injured.
Twelve of the guns were modified with “bump-fire” stocks, which are legal accessories that allow guns to fire at nearly fully automatic speed, officials said.
Meanwhile, FBI agents were slated to interview Paddock's girlfriend, Marilou Danley, in Los Angeles.
