Jason Bean & Marcella Corona
When bullets started to spray down from the 32nd floor of the Mandalay Bay Resort toward the thousands of fans dancing to the music of country star Jason Aldean, Savanna Chasco thought it was the speakers blowing out.
After the second wave of bullets began flying overhead, Chasco, a 20-year-old UNR student, began sprinting toward the MGM Grand. After briefly stopping while one of the friends in her group tried to persuade them that it was just the speakers malfunctioning, Chasco began running again as a third wave of bullets flooded down.
