Oct. 1, marked a somber anniversary for the country music community. On this date in 2017, a mass shooting took place at the Route 91 Harvest Festival in Las Vegas, killing 60 people and injuring more than 800 more.
It all began when 64-year-old Stephen Paddock opened fire on the crowd, which was gathered on the Las Vegas strip, from his window on the 32nd floor of the nearby Mandalay Bay Hotel. At the time, Jason Aldean was performing his headlining set, near the end of a three-day bill that also included Eric Church, Sam Hunt, Maren Morris and others.

"Hard to believe it's been 3 years since Route 91," the "Dirt Road Anthem" singer wrote. "That night was probably the worst night of our lives and not a day goes by that we don't think about the people who lost their lives and the families who have forever been affected by it."
"October 1st will always be a day for us that is extremely hard to relive," he continued. "To everyone in the Route 91 family, we love u guys and we couldn't have gotten through it without you."
Aldean's wife, Brittany -- who was at the festival and eight months pregnant at the time with their son, Memphis -- also recalled that fateful night.
"On one hand it seems like an eternity ago, a nightmare you try to forget. On the other hand, its vividness makes it seem like it was yesterday," Brittany -- who is also mom to their daughter, Navy -- wrote. "The sound, the chaos, the overwhelming sadness and heartache...it's something that never leaves you."
