Someone shot into a crowd of 30,000 people at an outdoor concert in Las Vegas near the Mandalay Bay casino last night. It happened just after 10:00 p.m. local time. Over 20 people are dead, and there were more than 100 wounded. JASON ALDEAN was performing when his set was interrupted by the sound of automated gunfire and he ran off the stage. There were several long bursts of gunfire, with long pauses in between while the shooter was reloading. The shots came from the 32nd floor of the Mandalay Bay.
